Hard to tell without testing. There are a few gems that can show colors like your stone. It could be from the Beryl group (Aquamarine) or maybe
Tourmaline, or Hiddenite.
could be most anything–even glass! Need to know specific gravity, double or single refraction, refractive index–That would at least let you narrow it down. Microscopic view of inclusions can help too.
If you won it from gemrockauction. Go back into your account and look at the “wins”. There you will find a list of everything you won.
You could also check your emails to see if the hiding you did is still available

It is a Spodumene. It’s heated to look like a Hiddenite. I also have one. It’s a good cut and has a pretty sparkle for jewelry. I didn’t think it was worth enough to keep it for investment.
Could well be irradiated, which have a tendency to color-fade, hence the huge difference in color between the item in the sales listing and the item once received in your hand.
Hi there
Nice stone have you checked the hardness yet if not you can try scratching glass unless you have a corrundum scratch plate and you could check the sg. This will help give you a good start hopefully this helps. Let me know and will go from there
