"I can not believe how beautiful this stone is. I just keep finding myself going back to look at it all the time just to make sure it is still there and it wasn't a dream. I truely mean that the stone I received is beautiful from the incrediable deep green color to the deep red that flashes back and forth from facet to facet as the light hits the stone. I now have a new favorite stone. Lab created Russian Alexandrite. BEAUTIFUL, BEAUTIFUL, BEAUTIFUL."

"I ordered this gem for a friend's birthday, as she is a June baby and Alexandrite is her birthstone. I think she will be very pleased with it as the cut is perfect and the color really does change under candlelight."

Fast Facts
| A member of the Chrysoberyl family, alexandrite holds a prized and highly priced position among jewelry and gem collectors. |
| A color change stone, alexandrite can appear green in daylight and change to a raspberry color in incandescent light, but other color changes are also highly prized. |
| Alexandrite was discovered in 1830 in the Ural Mountains on the day Czar Alexander II came of age, and thus the stones were named in his honor. |
 The primary sources for alexandrite are Sri Lanka, Brazil, Burma (Myanmar), Madagascar and Russia.
|
|
Alexandrite is a highly prized variety of chrysoberyl. Alexandrite only forms when aluminum/beryllium and chrome (which rarely occurs in nature) come together, accounting for its rarity. On Mohs’ scale of hardness, alexandrite is 8.5. It has a strong vitreous luster and primary sources include Sri Lanka, Zimbabwe, and Brazil (Minas Gerais).
Color
Alexandrite is typically found in blue, blue-green, and brownish-green shades. However, this phenomenal gem is known as "emerald by day, ruby by night" because of its ability to change color, depending on the type of light in which it's viewed. In the daylight and fluorescent light, alexandrite appears in shades of blue and green, but in tungsten (incandescent) light, it appears in shades of red. Other alexandrite color changes are possible (from blue to purple, from greenish blue to reddish blue, from brownish-green to brownish-red, etc.) and also highly prized.
