Hi everyone!

I recently (today!) got from my mom a really nice emerald cut Alexandrite. It was set in a ring she inherited and she wanted to use the gold so I asked her if she would give me the stone, which I didnt know what it was. It is a very nice one and it goes from a deep blue green/violet to a bright red wine color.

According to the measurements and this site http://www.csgnetwork.com/caratwtcalc.html it says its 12.53 carat. I've seen some sites where some of these go for very high prices

So now Im curious as to how much could my stone go for? And if people actually pay those prices...

And also for those that know... how do I know if mine is lab grown or natural?

If your Alexandrite is natural, then the price will depend on many factors, such as color, clarity, color change strength, origin, etc. It's not very common to use emerald cut ( baguette shape) for natural alexandrite, because fine Alexandrite are very expensive and gem dealer/cutter will try to save as much weight as possible, especially for large stones ( above 5cts).
So, assuming that you have 12.53cts natural alexandrite with strong color change, it can cost anything between $7.000 to $50.000.

To be 100% sure, you need to get an identification report from the respectful gem lab.
