Alexandrite is one of the rarest of all colored gemstones and is famed for its color change from green in daylight to red under incandescent light. Fine faceted alexandrite over 1 carat is more valuable than sapphire, ruby or emerald.

Alexandrite is a variety of chrysoberyl, with an excellent hardness of 8.5 on the Mohs scale, placing it right behind sapphire and ruby. Alexandrite is rare because of its chemical composition. Chrysoberyl is colored by traces iron and titanium, but alexandrite is also colored by chromium, which gives it the emerald green hue in daylight.

So many gorgeous stones! The only "complaint" I have is it's difficult to visualize sizes in mm. Perhaps some way to compare in inches?It has been a long time since I bought stones from Gem select, but the process wasn't too difficult.

The website is user friendly, has excellent selection. I've always found what I was looking for with Gem Select. When others don't have it they do. And most important, they have a way for you to pay without using PayPal. I cannot use PayPal they closed my account because of no cell phone.
