We have started our own line of jewelry, focusing on the spooky aesthetic without the high price tag. These earrings are a stunning little piece of history. The hearts are authentic French Victorian era glass beads (similar to jet, but glass, not wood) made sometime in the late 1800s. They measure 13mm x 11mmThese are EXTREMELY limited, due to the antique nature of the materials. The 6mm post is made of surgical steel.
