Vintage Coral Jewelry
Coral jewelry has a timeless appeal, and is more popular than ever today. It's really a rare specialty and one of my favorite types of jewelry. The demand for coral continues to grow despite new trade and harvesting regulations. All of my coral jewelry is vintage and has been in the U.S. for many years. Some pieces are from m the 1950's-80's.Coral is an organic gemstone and no two are exactly alike. You will see naturally occurring cracks, divots, surface crazing like tree bark and pitting on the coral pieces. Texture of coral is a smooth polish finish and some parts may feel like sandpaper or shark skin. During polishing process, you may see white or green polishing compound left in grooves of black coral jewelry pieces.
Unfortunately, coral reefs are endangered throughout the world. They are threatened by warming ocean waters, harmful blooming toxic bacteria, endless pollution, and destructive fishing and harvesting methods. Fine coral jewelry is getting rarer and more expensive all the time. The prices of coral have tripled in the last 2 years. Think of buying coral like an investment, the price of coral jewelry will go up, because the supply is very limited and demand is high.
The premier coral on the market is still "oxblood" red coral which is from the species Corallium. Most of it is harvested in the deep waters of the Mediterranean, and then polished and cut in Italy or Japan. Pink or Angel skin coral is always popular and commands a high price too. I have some pieces that are nearly impossible to find elsewhere. Lots of our customers say they didn't even know there were so many different types and colors of corals. Did you know it occurs naturally in lavender, black, blue, white, and of course every spectrum of red? Many people have never seen real Apple or Tiger coral. You have not been able to import it into the USA for decades, so the only sources are antique and vintage pieces.
I also have a supply loose coral beads available, if you want to make your own jewelry. Please contact me if you are looking for coral jewelry you can't find, I have more coral resources here in the islands.
Thank you so much for looking!

OK, OK, Gail has asked for a copy of my tome on working with black coral. Please understand this is an edited and somewhat shorter version of my Lapidary Journal article of Aug 2000 but it has been updated with new information and provides all the basic procedures to successfully work with this material. Once again I want to emphasize: BLACK CORAL OF ALL GENRE IS HIGHLY PROTECTED BY INTERNATIONAL TREATY AND IT IS ILLEGAL TO REMOVE IT FROM ITS NATURAL HABITAT WITHOUT PROPER LICENSE OR PURPOSE. ALL BLACK CORAL USED BY THIS AUTHOR HAS BEEN HARVESTED BY MOTHER NATURE AND IS CASUALLY COLLECTED FROM BEACHES. IF YOU WISH TO WORK WITH IT, PLEASE RESPECT THE LAW!
How to Collect and Process Black Coral
By Donald C. Dietz (An excerpt from his August 2000 Lapidary Journal article)
Florida’s Gorgonian black coral species most suitable for making jewelry are the sea bush (pseudoplexaura parosa [porous false plexaura]), knobby or spiny candelabrum (eunicea species), tan bushy coral (plexaura flexuosa), common bushy coral (plexaura homomalla), and Guadeloupe sea blade ( pterogorgia guadalupensis). Other species such as sea fans, sea rods, sea plumes, sea feathers and deadman’s fingers, can also be found but are either not black when dried or otherwise have more limited use for jewelry purposes. A few words are in order regarding sea feathers and sea plumes, often grouped with “black coral”. These varieties are not easy to clean due to the tough spines running the length of the long graceful stems. They can be smoothed, with some effort, and take a beautiful polish which shows them to be dark brown to nearly black in cross section but very dark brown with lighter brown twisted lateral bundles in the axial view. Cross sections of a large diameter limb can make excellent cabochons but I have found no easy method to bend or shape the brittle (and tough) stems other than slow heating. Straight polished segments make beautiful hair pins, etc. I have also found that the main stems from both of these corals and deadman’s fingers coral can be used to make beautiful beads.
Additionally, the true “sea fans” (gorgonia ventalina and gorgonia flabellum) as found in South Florida are rare and highly protected and usually either too small or too fragile for making jewelry, though they may make excellent specimens.
Often black coral is freshly blown onto South Florida’s beaches with little or no damage and with the calcareous outer shell (spicules) still clinging to the limbs. Black coral can be found caught in the rocks of breakwaters, tangled with seaweed or fishing lines at the water line or just lying on the beach. A sharp eye can often spot the top two to three inches of a coral branch sticking out of the sand. The reward may be a large buried branch or tree.
When found wet on the beach, the surface of black coral, sans the spicules, will appear muddy brown. But do not be misled because as it dries the layers compact, actually shrinking by a quarter or more in size and turn jet black. Actually, black coral isn’t black. It is a bit like “black” nephrite jade; i.e., a piece of thin nephrite held up to a light looks green or brown; whereas the coral appears brownish red.
Occasionally a coral tree with the spicules still attached may be found saturated with black oil. Wait until it dries and then break off the outer layer by pounding it gently with a wooden mallet or blunt object such as the edge of a board then wash with Gunk.
When collecting fresh black coral, you may notice a strong fishy odor due to saltwater saturating the coral skeleton and any remaining calcareous layer, or seaweed clinging to the branches. Clean the coral of debris before leaving the beach and rinse it with fresh water at a beach shower before putting it in your car. Rinse again at home with fresh water and dry it in the afternoon sun. By then the smell will be sufficiently lessened that it can be taken indoors to dry completely for two to three weeks.
It is important to pick up the coral as soon as possible after it is deposited on the beach because the hot sand “cooks” it and makes it brittle. Also the coral will begin to deteriorate and display brown “woody” spots. Eventually the entire tree will turn brown. This is difficult to remove and can result in loss of valuable material, though at times, small spots create lovely patterns that may be incorporated into a jewelry design. Remember, the larger and blacker the coral, the more beautiful it is, and the easier it is to clean and work into various designs.
JEWELRY CHARACTERISTICS
The physical properties of black coral generally support its usefulness as a jewelry material, but some also work against it. One attribute is its workability with the simplest of tools. It can be trimmed, smoothed and polished much in the same manner as a fine hard wood. It is ultra-light and when polished to a high shine feels and looks much like black plastic. Small or thin pieces may be quite brittle but thick material is quite durable. The polish must be protected from abrasion or it will become dull sometimes taking a beautiful patina. It chars easily when subjected to an open flame and the surface will “burn” and turn light brown due to friction when polished on a felt wheel. Thin wet limbs are easily bent or formed into many shapes and even tied into knots. When dry, it is stiff and hard and takes an excellent polish, however, after being formed to a particular shape it must be protected from water, which it will absorb making it soft and pliable again. Thus, beautiful hoop earrings could at best become horseshoe-shaped, or at worst a long shapeless stick.
I have collected bits and pieces of black coral for many years and have seen it fashioned as jewelry in parts of Japan and on Hawaii where it is revered as a gift of nature by native Hawaiians. But, while practicing the art of lapidary and gold and silversmithing for over 35 years, I never learned how to work with it until the article “Black Coral Pendant” by June Culp Zeitner appeared in the Jewelry Journal of the March 1996 Lapidary Journal. This article spurred my interest and after researching Lapidary Journal articles dating from the 1960’s, and various other references, I was hooked. Now I actively search the beaches hoping to find that one gigantic black coral tree. Meanwhile, I will settle for any little piece that looks like I can get an earring or perhaps a small pendant out of it.
WORKING WITH BLACK CORAL
Anyone with rudimentary lapidary, woodworking, or crafting experience can learn to work with black coral. The necessary tools will vary with ones’ talents and preference but will generally consist of small saws, various files, knives, several grades of sandpaper, polish compounds, a polishing motor and buffs, drills and various wheels, and other items that can be used to smooth, shape, bend and polish.
First look at the raw dry coral with its twisted and gnarled limbs, uneven surfaces, and tree like appearance for a hint of something unusual. Look for a particularly shaped crotch formed where one limb grows from another, or several off-shoots that might form a geometric (or un-geometric) design. Is a branch long and well shaped with few or no offshoots? Is it about the same size from where it leaves the main trunk to its end? Are the trunks and branches round, thick, and smooth or flattened with irregularities? If you do not have a specific design in mind these shapes may influence what you can or should do. If you have something specific to make, find the material that will fit your plan. Plan how to cut the tree keeping the pieces you consider usable and discarding the rest, though I find it difficult to throw any of it away unless a piece is badly deteriorated, too thin or heavily infested with disease. The latter is indicated by hollows or bubbles in the surface of the trunk and is filled with a form of calcium carbonate. Take a good look at the ends of the long branches. If hollow, they cannot be easily bent or shaped without kinking except in long graceful curves. The best coral is solid except for a tiny core usually about the diameter of a pinpoint. Look at the main trunk and limbs, which should also be solid and jet-black. If there are woody or calcareous areas growing into or under the surface, or hollows, you must decide to remove them or keep them as they are.
Cut and trim the coral into pieces that are the size or shape necessary to do a project. Use a hacksaw, jewelers saw, various cut off blades in a Dremel or Foredom tool, a small scroll saw or whatever you find convenient to cut through a piece of dry coral up to an inch thick. Small limbs can be snipped with side cutters but this leaves a ragged stub that must be filed down. The goal is cut the coral tree into pieces of varying size and shape that can be smoothed, formed, and polished. I find a 360-degree scroll saw blade very useful for getting into tight areas. Fine cutting can be done with a jeweler’s blade or small back cut saw. Motorized cut-off blades are quick and leave a neat cut but cause a lot of dust and, if used at high speed, can burn the coral. When using any motorized blade or tool, wear a dust filter mask and eye protection. The make up of gorgonius is protein with high concentrations of iodine and bromine but there is no telling what other chemicals or minerals are present. In any event, I doubt if the dust is good for your health and some people are allergic to it. Always wash any exposed skin immediately after working with black coral.
I have read articles that discuss the sanding or “grinding” of black coral when it is wet. I have tried it and, for me at least, it does not work. It appears that the wet process may be limited to the Antipatharian or deep-water variety of black coral that comes mostly from Hawaii but can also be found in some parts of the Caribbean. It is slightly harder and more stone like than the shallow water Gorgonian found in Florida waters. Other than soaking the coral in preparation for bending or forming of branches, the following steps are all performed on bone dry coral.
If you are working slender branches with offshoots, it will be nearly impossible to clean and polish in the crotches. Thus, it is important to open them up sufficiently to have access with smoothing tools and polishing wheels. Do this by holding the area in front of a heat gun (1500 watt hair dryers work to some extend but a heat gun is much better) for a few seconds and then gently open the crotch. This can also be used to straighten bent areas. Let the coral rest a minute or so and it will retain is new shape. It can always be reshaped by reheating and bending.
Remove nubs along the limbs by filing or sanding before generally smoothing any damaged areas. I use a heavy-duty half round wax rasp to remove large surface blemishes followed by finer files to smooth and shape the surface. Try to retain the natural curves or surface grain, but otherwise the surface must be even and smooth enough to get at it with a buffing wheel. Sometimes the grain is so clear and nicely formed it is wise not to polish it. The initial smoothing is a difficult step because it requires considerable hand strength to hold the coral steady while filing or cutting. Also, you may find coral difficult to smooth when filing in one direction due to growth grain, which may change several times throughout the length of a branch. Merely change the direction of your smoothing stroke to accommodate the grain. There is no one file or method that is best at this stage. Large pieces may be easier to manipulate but might require more filing or cutting. Small or thin pieces are more difficult to hold but may be naturally smooth. The process is much like cutting a stone–each succeeding step shapes and smoothes the material so that scratch lines from the previous step are removed. As you smooth the surface, blemishes may appear. Especially troublesome are the holes that result from removing off-shoot branches. Sometimes the core-hole extends into the middle of the mother branch, while other times it is very shallow. Nothing can be done about the former except to cut them out, while the latter can be filed out resulting in a longer more useful stem.
After filing, I have found various types of nail files/sponges to be useful. These can be purchased in most department or drug stores. I normally start with one that is an inch wide by 8 inches long with180- or 240-grit silicon carbide on a hard but flexible board. This does an excellent job on larger pieces and easily takes out the file marks. Some minor shaping can also be done but the general shape should already have been determined by cutting/filing. Next I use an acrylic nail file that has a 280-grit on one side and 320- or 400-grit on the other with a foam board in the middle. This board is softer and follows the rounded contours well. It also gives a nearly ready to polish surface. Hard to get places can be cleaned and smoothed using various plastic scouring/sanding pads. These are excellent for getting into crotches and between limbs. Final sanding can be done with worn 400- or 600-grit silicon carbide paper. These final smoothing steps are important because they take the work out of polishing.
Any remaining scratches must either be re-smoothed or polished away using considerable pressure against the polishing wheel, which could result in overheating the surface and burning the coral. When this occurs, it is nearly impossible to remove the resulting brown area. Brown speckles (caused by deterioration) that remain after final sanding can sometimes be removed by scraping across the surface with a very sharp hobby knife or a razor blade. This removes material more quickly than filing or sanding, and leaves the surface relatively smooth. With practice, you can control exactly where and how much material is removed.
I have found it best to polish coral before forming, bending, or making the final piece of jewelry. Forming and bending may result in curves or corners that are difficult to access for smoothing and polishing. Even after soaking and forming the coral, about 80 to 90% of the pre-polish will remain. If you intend to carve the piece, it is wise to pre-polish as it can reveal imperfections or an irregular shape that could affect your plans. At this stage these can often be corrected.
ZAM is an excellent overall polish for black coral. Fabuluster, black emery, rouge, and some others do a good pre-polish but finishing with ZAM seems to give the highest luster. Whatever polish you use, use it on a multi-layered, one inch wide sewn muslin cotton buffing wheel. Do not use felt; the high surface temperature will quickly burn your coral. A 3450-RPM motor is recommended but a 1725-RPM or just about any other motor can be used in a pinch including a flex-shaft. If the buffing wheel becomes too hard cut the stitches to soften it. This will ensure the polishing compound penetrates the wheel and gives good polishing action. Use smaller 1-1/2” to 2” inch diameter cotton wheels on your Dremel or Foredom tool for the hard to get places but be careful as these wheels may “burn” the surface or grab the piece from your hand.
There are some tricks to getting a good polish on black coral. Keep the wheel well loaded with polish. Initially, keep the piece horizontal to the wheel and support it with your fingers or a wood block. Run it back and forth the length of the coral branch, using moderate to heavy pressure. This will quickly highlight any remaining filing, sanding marks or irregularities. Under the proper speed, pressure and polishing medium the outer layers of protein melt and flow. Thus, minor scratches or surface blemishes may polish out. Otherwise, correct them by additional sanding before continuing. After you are satisfied all such marks are removed and the coral has an even shiny appearance, run the coral lengthwise (vertically) up and down the wheel parallel to the grain using light pressure. The resulting shine will be well worth all the effort you have put into preparing your coral.
FORMING AND SHAPING
Shaping black coral is an experience in itself. Thick solid pieces can be carved or sanded to any shape. Keep in mind the center (or slightly off-center) core can suddenly appear right in the middle of your otherwise beautifully carved humped-back whale. Be aware also of any hollows or other blemishes previously identified or suspected. Start with easy shapes; an easy one to make looks like a baseball bat. You may also incorporate any original curve into the new form. More sophisticated bends or curves can be attained by soaking the polished black coral branch in water (hot water does it faster; cold a bit slower but just as effective) and forming it around a dowel, or inside various items such as a jar lid or a can. In the past few years, I have used the heat gun mentioned above, to bend large diameter pieces for necklaces/bangles or to readjust/tighten designs such as knots and braids. While learning to work with black coral, select only solid pieces, as you will find the hollow ones difficult to work with. As you gain experience, you will find the hollow limbs useful in some forms as well. Following are some examples to obtain specific shapes.
To make large hoops, place two wet branches 4 to 10mm in diameter inside a jar or can with a 2 inch inside diameter. If you want the ends to meet when dry, overlap them by about 1/2 inch. To create a hoop with a 1/4 to 1/2 inch gap make the ends meet when wet; they will separate as they dry. If the branch has some irregularities in its length, wait until it is just about dry, remove it from the jar/can and place a flat weight of about 4 to 8 ounces on it for 12 hours. This will insure it is a flat round hoop. Adjustments can be made with the heat gun.
To make several other shapes, drill a hole in the end of a 1/2 to 3/4 inch wood dowel, insert one end of a wet 4 to 6mm x 6 inch branch and wrap it around. Tape, nail, or pin it at the ends to keep it from unwinding. Let it dry for at least 24 hours and slide it off of the dowel. Cut the tightly wound coil lengthwise to make small hoops (as in making jump rings). Dampen the hoops slightly and dry under a 4 to 8 oz weight to bring the ends even or adjust with the heat gun.
To stretch the tightly wound coral into a corkscrew, slightly dampen or heat it, pull the ends apart until it is the shape you desire and let it dry/cool. A simple crossed loop can be made by bending a wet branch around a 1/4 inch dowel and pinning the coral at the point where they cross. Let it dry for 24 hours.
Many other shapes can be obtained by the use of clips, dowels, jars, cans, boards with pins or holes in them or special “jigs” designed to hold the coral in a specific position until it has completely dried. If a shape does not quite conform to your specifications, dampen or heat it and try again.
Use steam from a tea kettle to quickly form or correct bends and curves. A propane torch, alcohol lamp, “lil torch”, or heat gun can be used to gently heat the coral for forming. Heat should be used only as one becomes more experienced as the coral can easily burn or become misshapen. The secret is to not be in a hurry. Give the coral plenty of time to set-up and dry or cool otherwise it may become warped. When wet, thin branches of solid coral can even be tied into various kinds of attractive knots, provided they are not pulled too tight too quickly.
FINAL WORK
After the black coral has been shaped, it can be drilled with a variety of twist drills or points to fit sterling silver or gold findings. Eye pins or other findings can be glued into the coral with epoxy. The ends of hoop ear rings or bracelets can be finished by making a small bezel cup, adding a jump ring and attaching the cup to the coral with epoxy. There is almost no end to the variety of designs for black coral. It looks just as beautiful with gold or silver; add pearls, red or pink coral beads, or gemstones to achieve your concept. Stones such as turquoise or opal are beautiful when inlayed and framed by the jet black and shiny coral. (Hint: When drilling, do not push the drill in too quickly as it will expand, graband subsequently break the drill. Instead insert it in short quick strokes. This cleans the hole and allows the coral to cool slightly).

Black Coral – Value
Larry asked the value of some black coral he found in an estate.
I’ll have a go at answering this question, but you all must understand there are many many variables in determining the value of black coral ranging from the kind of coral it is, to the color (yes there are many colors of black coral), where it came from and whats been done with it to name a few.
Without going into too much detail, lets start with what kind of coral it is. Some months ago I was at a gem show and noticed a dealer selling ‘black coral’. I stopped by to check it out. There were boxes of fragments out, all displaying 2-3′x1-1.5′ pieces all nice jet black. But, when I hefted one, I new it was a fake. It has heavy, not light and wispy like true black coral. I challenged the dealer who was asking a ridiculously low price and admitted (with a bit of conjolling) that it was hard (calcareous) coral dyed black. Value, $5 a piece. I bought two just to have a reference.. Sure enough I ground a small nub off and it was white inside!!!
Next is it Antipatharian or Gorgonian? The former is usually (not always but most of the time) a deep water coral and is considered by some (mistakenly I believe) to be the only true black coral. The latter is always shallow water coral and is what I work with as it is readily available on Florida’s beaches. The former is quite expensive BECAUSE it is deep water and its collection is very very highly controlled. I used to get some now and then from divers in Hawaii but can find very little on the market now. I did see some searching today priced at $10 for 50 carats! That’s about 10 grams (a piece roughly 1/4″ thick by 5″ long. Most of the Antipatharian coral is siphoned off to the big makers like Maui Divers or Bernard Passman.
The Gorgonian blacks are more readily available and therefore not as valued. Not that they are that much different in their content or make-up….they are essential both skeletons of the coral colony, both made primarily of protein, most are usually black or brown in color, same hardness, same structure (rings like a tree – though Antipatharian rings usually are a bit wider than Gorgonian) virtually the same specific gravity, etc, etc. The only difference, perhaps is in the nature of the taxology of the animal, the Gorgonian is an ‘octocoral’ because the animal has 8 septa (some say all black coral has 8 septa) but lately I have seen references saying the Antipatharian has only 6 septa which means it shouldn’t be considered a true black coral!!!?? Go figure!! Sorry for rambling, but you see there is a difference in the value based on the above.
Now, some Gorgonian black coral ain’t even black (remember we are only talking about the skeleton here because the animal ((when its alive)) that inhabits the outside can be any color of the rainbow). It can also be various shades of both brown and black. There are sea plumes, considered Gorgonian black coral because the animal has 8 septa, that actually produces a skeleton of beautiful bundles of brownish fibres that take on a golden color when polished. It is much tougher than Gorgonian and can be difficult to work with due to the sharp spines along the main stems. It is also harder to bend and shape. And the list goes on.
How can you tell the difference? Well, if it hasn’t been smoothed and polished, the skin of Antipatharian coral has a rough texture I equate to shark skin or medium sand paper. If you can see them, the rings are often wide and separated. Sometimes you will see finished jewelry with white rings. That is actually polish compound left there to define the rings.
Gorgonian coral rough has a relatively smooth skin, the rings are thin and usually well packed together with a very small brown core that can be hollow at times.
In either case, if its been smoothed and polished you will not be able to tell the difference!!!
For a rough medium tree (a main truck of about 1/4″ and overall length of 10″) of Gorgonian with long, nicely shaped limbs and two secondary branches, I usually charge from $5-10. When the main trunk is wider, longer, more branches, etc, good solid black color with no problems the price can go upwards of $20. Select pieces that are cut for specific purposes can be worth $2-5. Antipatharian coral of same size and quality can go upwards of several hundreds of dollars. So you see it is important to know what you have!!
I could go on and on but I think you get the picture. Before actually evaluating what you have Larry, do some on -line research to see whats currently out there.
Of course, processed coral is a whole different ball game, especially if its been made here in the States and not done by some kid in Timbuktu working for $1 a month. There is a lot of ‘trinket-ware’ out there and tons of beads, but true pieces of jewelry made with black coral (especially if its not just a little slice added to $10k worth of diamonds and gold) can be very exciting and worth a considerable sum due to the hand work needed to process, design, shape and polish the coral.
Good luck with your coral and I hope this might also help others out there. Cheers, Coralnut – Donral and I hope this might also help others out there. Cheers, Coralnut – Don
