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.
I purchased a yellow sapphire for about $145 with shipping and the Gem Certificate. I used the $10 shipping option and it arrived 2 days early. (Please note that if you want a Gem Certificate, it can take up to 5 days longer to be delivered) The gemstone looked exactly like the picture and video. I am so excited about the quality and price! Please note that the Gem Certificate does not say the clarity for some reason... 150% happy with this website, and would use it again!
