Elegant Silver Pendant with Clear Gemstone

Pendant only, chain is just for the pictures. Stunning silver colored pendant featuring a clear gemstone moissanite?cz?Perfect for adding elegance to any outfit. Part of an estate I inherited. it looks like silver or white gold but I don't see a stamp. I can't imagine my aunt owned a diamond of this size, so I assume it's moussanite or cz, but it's really gorgeous and looks real.
