Chrysoberyl (Synthetic) Gemstone & Information | Gemopedia by JTV | Gemopedia™

Chrysoberyl (Synthetic)

Synthetic chrysoberyl is produced by a process called the Czochralski method. Material containing the elements that make up the mineral chrysoberyl (beryllium, aluminum and oxygen) are melted in a platinum crucible along with elements that produce the desired color (in this case, iron). A small chrysoberyl crystal (called a seed) attached to a rod is then dipped into the melt and slowly pulled away as the crystal grows around the seed. For this reason, the Czochralski method is also known as crystal pulling. Synthetic gems have the same chemical, optical, and physical properties of their natural counterparts, but are a more cost-effective alternative to a natural gem.
