I am researching for a source of faceting rough and mineral specimens
for my newest jewelry collection. I’ve spoken to “New Era Gems” in
Grass Valley, CA and they seem to have a good selection and they are
very knowledgeable. Has anyone done business with them? I’ve
designed my jewelry pieces to have half drilled rough stones from say
15 to 25mm and large minerals fully drilled. Does anyone have
experience drilling quartz, green garnet, topaz, beryl, as examples.
I’ve been warned of the concerns of cracking or shattering the gems.
Any advise is greatly appreciated.
