"I was very disappointed when I received the gem and realized it was not changing colors. It stayed a constant bluish green. There was not one purple or red spec in the gem. I was really looking forward to making a pendant out of this gem."

"I'm happy to add this stone to my collection. The color is a little dark, but it is pretty when viewed outside or in certain indoor lights. You can see a definite color-shift. I love emerald cut stones. The cutting is very nice on this one."

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.
