Paul likes Fluorite best.  Here is what he says got him started with this like: “Oddly, I was fascinated as a young kid by all the different colored cleavage pieces that were sold in tourist traps.  Didn’t know at the time what they were or how they were made, but the hook was set and I have been collecting since.”

I also like fluorite.  I have quite a few pieces of it in my collection.

Fluorite is a mineral that comes in many many colors, but is mostly known for it’s brilliant purple variation.  It can easily compare with amethyst.  Fluorite is often fluorescent, typically in a blue shade. 

When Fluorite is found it often times is in with other minerals. The best way to tell if you are close to some fluorite is by the crystal habits where you are.  If the accompany rocks are harder than calcite, but softer than quartz, chances are you will find some fluorite.
