Shape - Round Shape. Dimensions: 5mm -0.54-0.87 Cts. Lab created Alexandrites have the same optical and physical properties as their mined counterparts. The most spectacular and prized transformation is from green in daylight to red in incandescent light.

Alexandrite the June Birthstone.Often called “emerald by day, ruby by night,” alexandrite is a pleochroic gem that exhibits a lovely green in daylight and changes to a smoky purple-brown in candlelight.While most pleochroic gems show hints of different colors in other light, alexandrites change color completely.The main pleochroic colors of the alexandrite are orange,green, and purple-red,but it is not the gem's pleochroism that causes this effect,but rather the way the mineral reflects light.
