Copper Electroformed Pendants

Here we have some various materials of crystal points that have been electroformed with copper. Each one is ever so slightly different in design. I only have one of each material, and all of them have the bale part wrapped with a half round copper wire. They are all on 24" inch copper plated chains. The materials are as follows, from right to left:

Onyx
Quartz
Tigerseye
Sodalite
Rose Quartz
Amethyst
Red Jasper
