Copper Brown Goldstone Rectangular Signet Cab - Vintage
Copper Brown Goldstone rectangular cabs - man-made gems in rich coppery tones, with sparkles in the light.
These vintage stones were cut pre 1980 as signet stones for rings and cuff links. They still have traces of adhesive residue on the unpolished backs from their original supply cards - please see photos.
