About alexandrite
Alexandrite is the color change variety of chrysoberyl: greenish in daylight, reddish to purplish under warm incandescent light. At 8.5 on the Mohs scale and with excellent toughness, it is one of the most durable gemstones. It has one cleavage plane, but this is rarely a problem.
Cleaning
Warm water, a drop of mild dish soap and a soft toothbrush are all you need. Brush behind the stone too, where dust and skin oils collect, then rinse and dry with a soft cloth. Ultrasonic and steam cleaners are usually fine for a faceted alexandrite, but skip them if the stone has fissures that reach the surface.
Wear and storage
Alexandrite is hard, so it can scratch softer gemstones stored with it. Harder stones such as sapphire, ruby and diamond can scratch it, so keep it apart from them and store it on its own in a gem jar or a soft pouch.
For your jeweler
This alexandrite is untreated. Alexandrite handles normal setting, re-tipping and polishing well. If the stone has fissures that reach the surface, keep it out of direct torch flame and acid pickle.
