These are Tanzanian Winza Sapphires. Prior to 2008, fine Sapphire and Ruby were becoming scarce, when a deposit was found in Winza. It produced some very interesting material, but still mostly very small pieces.
I was finally able to get a hold of some of pretty reasonable size, but as mentioned, they are hard to source, and when found, are very expensive. I was lucky enough to get a good price, so I could pass that on to you!
8mm Winza Sapphires set in Sterling silver with a mirror finish and hanging from simple hand made hoops.
These earrings hang approximately 1.5”” from ear lobe
