Unique cut glass pendant and matching earrings. This item was purchased at an estate sake held at one of the last mansions left in Chicagos historic district. The chain is silver overlay and is 18 inches. There are light scratches on the glass but not noticeable enough to take away from the oddity yet curiosity of this necklace. Sorry I do not know the designer. All Estate Sale jewelry has been appraised. We clean and UB sanitize for your protection. Questions or comments welcome .
