Cubic zirconia is crystallographically isometric,
an important attribute of a would-be diamond simulant.
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.
