What's that one on the bottom row second one on the right purple one?

That is a boule of synthetic Alexandrite. It's a color change stone, so it's that purple color in normal indoor light, but it's a light blue in brighter sun or fluorescent light.

Oh my gosh that sounds amazing where did you get such a mineral?

I got it on eBay.

I'm aware of that article. I'm just starting out with faceting and don't want to buy a material that costs several thousand per carat if I can't be sure of making a good return on it. That and alexandrite over 1 carat are rare, so with synthetic, I could make larger stones that show off the gem's color change more brilliantly. Rest assured that I would never attempt to sell a synthetic stone as a natural one.

Oh no its not that.. i'm just saying are you sure its synthetic ALEXANDRITE? (They were mentioning it could be cheaper gemstones or other sorts of stones being portrayed as Alexandrite...)

Oh. Yes I verified that. The two most common materials used in place of alexandrite are corundum and garnet. Corundum has a Moh's hardness of 9.0, garnet has a hardness of 6.5-7.5, and chrysoberyl (alexandrite) has a hardness of 8.5. If you have the necessary materials, there's a very simple test to figure out what you have.

You need corundum (sapphire or ruby), beryl (emerald or aquamarine which has hardness of 8.0), and the questionable alexandrite. If it's alexandrite, it could be scratched by but can't scratch corundum and could scratch but could not be scratched by the beryl. If it's corundum, it could scratch or be scratched by the corundum. If it's garnet, it couldn't scratch either Beryl or corundum, but could be scratched by both.

If you know Moh's hardnesses of various materials, you can use that knowledge to rule out or confirm most rough stones' identities.

Very nice collection :3

Awesome collection man :3 Looks like a lot of crystals!

How nice. Cant wait to see finished pieces
