Stamped .925 Sterling Silver. 12mm X 8mm Marquise Zirconia. Upper shank decorated with round Marcasite
Marcasite is a metallic, black-grey stone, similar in chemical makeup to pyrite, but different in crystal structure. It is machine cut and polished, giving jewelry made with it an antiqued vintage look.
Cubic zirconia is crystallographically isometric,
an important attribute of a would-be diamond simulant.
