This is a natural specimen of Vesuvianite, named for Mount Vesuvius in Naples where it was first found in the 1750’s. It has an almost black, dark red-brown color. It is naturally glossy and has a texture of black tourmaline and sits beautifully claw-set in bronze. As with all these specimen rings they are slightly delicate, try not to drop it! Otherwise it’s fine! The setting will keep it safe in your finger! One of a kind size 7.
