Could someone please tell me what the difference between these two rocks are? I had them tested with some other stuff we found like gold, silver, garnet, quartz. The test results came back telling us that all of our so called amethyst are fluorite. Can you tumble fluorite? How fragil is it? How should I tumble it? Any ideas, if ya do Please let me know.
Thanks again momma

Try (fluorite)--start running in 220 and check every day-- This is called the "majic rock" because it will vanish before your eyes...

Hey Momma, Flourite is a very soft mineral with a hardness of 4, compared to Quartz which is a 7. If you tumble, just be very, very careful and check it often.

Flourite is very soft! Be careful- It will take a nice shine!

Flourite and quartz are two different animals. A faceted amythist is worth about 25$. A faceted flourite it worth about 1000$ for the same size piece. That is just a rough statement, and is meant to show one difference. Flourite will disappear before your eyes, but, if you can tumble it, it will out shine most unless something rubs against it. It cracks easily when set also.

So that would explain why all of my Flourite that I tumbled when we found it and thought it was Amethyst went to almost NOTHING. We put them in stage 1 and in 3 days thay were smaller then a dime size.
Another question does anyone know what Arsenopyrite is? We also found some of that.
Pyrite mixed with Geoth(spelling??)
Not really sure what these are but this is what we found.
Any ides PLEASE help
thanx

Helo Momma,
Arsenopyrite is a Sulfide related compound.It has a hardness of 5.5 to 6. color is tin-white, grey, tarnishing to yellow. It shows to be found in the following areas ... Germany, Austria, England, Sweden, Canada and Cunnecticut and Colorado.
It is the most important ore of Arsenic.
Hope this helps,

Well, we must be lucky if we found arsenopyrite here in Montana he he just kidding. Thanks for the info BearCreak. The friend who found it has it up on a shelf just looking pretty. He thinks it prett cook to have something like that in his living room. Is it dangerous to have around for people and animals?
Thanks again momma

I'm a wannabe chemist nerd, so here is the big difference between the two:
Amethyst is: SiO2
Fluorite is: CaF2
They have nothing in common at all except that sometimes they're both purple.
Bonus - Arsenopyrite is: FeAsS

Momma, where did you take the stuff to have it tested? Was it very expensive to have it done?

Hey Rose, I sent all my findings to a minerologist(spellin) and all I had to do was pay for shipping. When they were done they send it back with a print out of what they found. Pretty cool. It was really cheap.
If ya want to try your self just find a min. and ask them how much. Hopes this help in case you want to do the sam thing.
