"Pulled Alexandrite" is a term used to describe a method of creating lab-grown alexandrite gemstones.

In this method, a synthetic crystal is grown using a process called the Czochralski method, which involves melting a mixture of materials in a crucible and then slowly pulling a seed crystal through the melted material to create a larger crystal.

To create "pulled alexandrite", a mixture of aluminum oxide, beryllium oxide, and chromium oxide is used in the melting process to create a crystal with the same chemical composition as natural alexandrite. This crystal is then carefully cut and polished to showcase its color-changing properties.

Pulled alexandrite is chemically and physically identical to natural alexandrite, and can be an affordable alternative for those who cannot afford a natural alexandrite gemstone. 

***This is the true lab created Color ChangeAlexandrite - Chrysoberyl, not a Flame Fusion Corundum imitation (simulant). 

Material is completely the same as best varieties of the genuine Alexandrite - Russian, Brazilian or Rhodesian. The color change is from the green in daylight to purplish red in incandescent light. 

Same quality natural Alexandrite is extremely rare and much more expensive than Diamond, especially stones bigger then 3-4 Carats. 

Crystal grown by vertically pulled (from melt) method, also known as Czochralski pulled. Cut stone quality is AAAAA - as high as possible.
