in regions where volcanism was very common, in the ruins of old volcanic archipegios like New Hampshire/ Vermont Conneticuit river valley, Gemstones are very very common.
They are not rare.
crystals are common.
we have hillocks made of quartz that is has inclusions of all kinds of other stones.
you can buy fluorite in abundance on line. just look on ebay. They often sell it by the pound.
I keep it as an ornamental stone, having bought a lot of it years ago. Mostly it's green and sometimes has part that are almost purple. I have strands of it that I bought at a rock shop and I use those to keep other things from falling off my shelf (things with wheels which will roll) those strands were less than ten dollars for a lot of it, and it's large beads (about an inch and half by 1/3 of an inch) both green and purple.
again: very very very common.
if it has inclusions of rarer stones, of course, it's more interesting, so probably that gets a higher price.
I have it because I like the color.
