Synthetic Pulled Alexandrite - 37.2 Carats - Grade A - Faceting Rough for Gem Cutting
37.2 Carats of Grade A Pulled Synthetic Alexandrite rough for faceting and gemstone creation.
Alexandrite is one of the most amazing stones. The main difference between alexandrite and other gemstones lies in its unique ability to change color depending on ambient light. Alexandrite has a bluish-green or grass-green color when white fluorescent artificial lighting is used, but turns violet or ruby-red in sunlight or candlelight. This is called the alexandrite effect phenomenon, and is commonly used with other minerals that are able to change color. For example, garnets, which can change color, are also called garnets with alexandrite effect.
This Synthetic Lab created Alexandrite was grown by Czochralski method.
