Glad to have been such a timely contribution~

Wow~ thanks for such high praise.

I'll agree, it can be beautiful material indeed. Humanity was quite fortunate to have something so attractive be so much more available.

My pleasure to serve. Catherine the Great's favourite stone was Amethyst~

Thank you ~!

Thank you, and glad it was fascinating ^_^

There's lots of potential in both, absolutely.

Thanks~ glad to be of service.

You can definitely facet the micro and crypto-crystalline varieties, as they're quite tough. They just don't benefit as much from the scintillation of internal light reflection. If you're looking to put some sparkly reflection on the top of the stone, that's definitely doable. Long story short - can do it, but result is less exciting.

My pleasure~

Woohoo~ Welcome to the top :D

Hi Oakley, i would expect there to be colour change on synthetic alexandrite. Of course they'd need to be tested to say much further, but there may have been some other similar looking stones mixed in (accidentally or intentionally) to the parcel.

Opal is made up of silical gel spheres, so there is some real similarity chemically. Very close observation~

Citrine has a hardness of 7 too, so both it and amethyst can cut glass (usually 5.5).

Excellent point, Brian. @teodor Anything harder than glass that is able to sustain a point should be able to break the surface tension of glass and therefore cut it. If we look at the commercially available glass cutting tools with a wheel, what is the wheel made out of? Strong chance that many of those are just hardened steel (often 7-8 mohs). Glass is chemically similar to quartz, but the crystalline structure is important. Just like diamond is "just carbon" but has a different crystal structure that makes it incredibly hard.

@@GemologyforSchmucks You will loose subs with this way of "truth" , but it is Your choice. Hope / that You have a son someday ! / this venture bring You something other than probs./ Meaning, that I continue with The Market !/ Peace Best Regards, Teo

@@teodorkutzarov3866 Huh? What do you mean? These are facts. Citrine can indeed cut glass, why would you call that a lie?

@@briancurtis6022 You are still young, but one day, maybe the calculation will hit you like a train ;) Crave in this sphere and You`ll eventually get the talk !

Congratulations, I hope you love your stone very much.

I want sale that gemstone you have any buyers sir

Supply chain is a peculiar thing indeed. My philosophy is that I just buy the items that I believe to be genuinely rare, at a price that im prepared to accept. If the vendor wont come down to my price point, then we don't have a sale and I just move on with my life.

At the end of the day, the price point of any object is agreed upon between the buyer and the seller. To know what is a "good deal", you need to look at comparable goods that are available in the market. If there is nothing else similar, then its just down to negotiation.
