Solid 925 Sterling Silver Mens Unique Gemstone Ring Black / Red Stone Size 10 - Nice condition, as shown. Buyer may wish to polish this item. It is unsigned, and there are no metal marks, so we acid tested it, and it is SILVER. I am not a gemologist, and am not sure what the stone is called. I have seen some similar looking stones on the internet referred to as Unakite, Blood Stone, and Yemeni Agate, but I cannot tell them apart. Please see the photos and decide for yourself. The band is about 1/3" wide, and the ring weighs about 11 grams.
