If you know you know… Extasia of Germany has a cult following and create limited editions of beautiful cameo pendants. This one is a coveted black carved jet glass medallion in antiqued brass setting. The woman in the cameo appears to have a snake on her collarbone - though it could be hair! I like the snake idea though. It also has a braided hair border, a nod to mourning jewelry. Medallion pendant is just under 2”. Chain is adjustable from 18” to about 19.5”. Collectors item for sure!
