7 1/2 inches long- Very sultry smokey greyish/corn flower sea green Apatite in stamped 925 sterling silver. Lab grown specimens...They may call them man made, but the fact is, they don't "make" gemstones- They grow them. They're minerals- Using the same basic mineral compounds as the ground stones, plus heat/pressure, & many months before they're something that can be placed in jewelry. But if they're laboratory grown, I will always say that in description, as I sell natural earth gemstones too...The first photos i took st night inside under a lamp. The last 5 photos were taken outside in daylight....Thanks for browsing, and if you'd like to see all the other sterling silver and gemstone jewelry for men & women that I have posted on eBay, scroll down and tap sellers other items- all are free shipping.  Peace.
