“Here are some of my favorites from my collection! Left to right, top to bottom:

Fluorite, green calcite, two sides of my labradorite, tourmaline on quartz, tiny double terminated quartz that has two points on one side (triple terminated???), lapis lazuli, peridot, ruby (more of a pink-purple sapphire than a ruby), sapphire, and a beautiful quartz crystal with amazing gas inclusions! They look like a tiny galaxy.

The two quartzes are amung many mined in Arkansas (Jim Colemans Crystal Mine) and they pretty much all came with this rusty junk on them. Do you know of any way to get that off and/or what that stuff is? The included quartz would be so much more beautiful and clear without those spots. I have a feeling it might be some kind of inclusion I wont be able to remove haha.
