Alexandrite

[ilovegemstones]

It looks like the silk that gives some chrysoberyl the cat's eye effect. Alexandrite is a variety of chrysoberyl - it looks like a alex to me!

If you have questions regarding your stone or ring I would create another seperate thread in the Colored Gemstones forum so as to not threadjack the OP! Thanks!

Okay, sorry

Anybody who tells you they have (or are selling) a Russian Alexandrite is probably very mistaken. If you read the book mentioned above you'll know that the tiny amount of Russian Alex were mined out almost 100 years ago and most of it was under 1ct. Also the quality of the stones were generally poor. Even long time collectors haven't usually seen a good Russian Alex.

So, basically, if somebody is selling a "Russian" Alexandrite I would steer well clear of them because they're unlikely to know much about Alex. If it's a well known vendor that you feel you can trust then by all means buy the stone on condition that a lab report confirms origin. IF the stone is poor in clarity and colour change there's a very very very slight possibility that it may be Russian.

In the meantime, please read this book because it's an eye opener! https://store.gia.edu/Russian-Alexandrites-p/0201293.htm

It is natural alexandrite - The milky zone are fine tube like negative crystals parallel to a-xis. I have a stone from Sri Lanka with similar inclusion. Dr. Schmetzer described them in his article about alexandrite from Lake Manyara / TAN. Same seen from India and Brazil.
