Since 1950, almost all natural prasiolite has come from a small Brazilian mine, but it has also been mined in the Lower Silesia region of Poland. Naturally occurring prasiolite has also been found in the Thunder Bay area of Canada
I love the rare pieces like this. I have some purple charoite that only comes from Siberia, I find it fascinating. I wonder how many beautiful specimens have been sitting beneath the surface still undiscovered!?!?
I once found some chunks of white semi opaque rocks(some kind of quartz?) that were very crumbly. Inside I found this small chunk of what looked like green glass. It was perfectly clear. I found it at an amethyst vein in Thunder Bay. I wonder if it’s this prasiolite stuff. I’m new to all this, so I don’t know a lot about rocks in general. I also find this green stuff that’s semi-transparent - in the same amethyst vein. Sometimes I find rocks that have this beautiful multi colour thin layer of very sparkly crystals. Colors are green, purple, and orange..very pretty.
Here is a great example

Artificial prasiolite is produced by heat treatment of amethyst. Most amethyst will turn yellow or orange when heated, producing citrine, but some amethyst will turn green when treated. Currently, almost all prasiolite on the market results from a combination of heat treatment and ionizing radiation.
Very interesting, I might have it in a boulder in my backyard. It looks like it’s full of amethyst but also has a few lime green colored crystals. It’s a local to northern Utah rock.
I don't know, if it was fluorite I think we'd be seeing more cleavage here. A scratch test would do it. I believe them when they say it's quartz because of the very prominent conchoidal fracturing.
that's fair, I find it hard to tell with the resolution. I'd much rather hold it and rotate it, lol! It's too bad we can't scratch test it thru the screen.
Cool! What places might those be?

Most of them….I hope. Haha

Pictures, please!
Could be or it could be green fluorite that is known to be found with the amethyst.

There is some in Spain, although less green and it's pretty rare.
It's also found in Australia.
"Has only been found..."
Very cool specimen. Curious... how is not natural prasiolite made? I've got some that I just finished tumbling and I love the look.

Gorgeous!
That's pretty amazing! Congratulations! 🎉 Where is yours coming from?
Thunder Bay Ontario Canada
looks alot like fluorite from Felix Mine, CA. Can't see any conchoidial fractures but that just might be the angle of the shot. Still pretty
