Handmade Gemstone Alexandrite Jewelry in Russia

Tuesday, March 20th, 2012

Alexandrite is a variety of chrysoberyl that displays a color change depending on the nature of the ambient lighting under which it is shone. Alexandrite is on of the few semi-precious gemstones discovered that displays a color change. The stone is hard and tough, so it is perfect for handmade gemstone jewelry.

This semi-precious gemstone is the result from small scale replacement of aluminium by chromium ions in the crystalline structure. This causes the stone to take in and absorb light over a narrow range of wavelengths.

Alexandrite is a hard stone and looks very elegant set in a ring or a pendant. Its color change distinguishes it from other gemstones.

Some of the less valuable Alexandrite gemstones are blue/green in the daytime and purple/red in incandescent light. Alexandrite has also been found in Brazil, Burma, India, but these gemstones have been found to be not quite as good as the Russian and should hopefully cost less.

Alexandrite has a hardness of 8.5 on the Moh’s scale. It is a hard gemstone and is often carved into an oval, pear or cushion to be set in a silver or gold gemstone ring.

It is a good idea or important to check the carat weight of your Alexandrite. 1 carat is about 0.20 grans. Usually, a ring or pendant is sold with 0.75 of a carat. Two carats are very rare and usually quite expensive.

It is crutial to check the stone and the band’s thickness. A ring and stone must be the same thickness. Alexandrite goes very well with gold, but can also look nice with white gold or silver. When purchasing a silver gemstone ring it is important to look at the back of the ring to make sure it has a finished look. The back of the band and stone should be just as well polished as the front.

The purest Alexandrite still comes of the Ural Mountains in Russia. It is very rare. However, there are mines in Brazil, Burrma, and Tumndura who also mine alexandrite, but this Alexandrite is a blueish green and dark purple.

Once you have bought your Alexandrite it is very important to look after it. If looked after properly it can be treasured for a life time. Try to get it remounted as little as possible. As any other gemstone, it is important to keep it away from other chemicals and hard solutions. Do not expose it to sharp blows and heavy scrubbing, which would very likely affect the color.
