buy natural alexandrite
Natural alexandrite is more expensive than most gemstones, including sapphires, rubies, emeralds, and diamonds. Top-quality Russian authentic alexandrite has sold for as much as $10,000 for one carat.
GIA evaluates alexandrite but does not grade it. A GIA Colored Stone Identification & Origin Report assesses the characteristics of a mounted or loose alexandrite (weight, measurements, shape, cutting style and color), indicates whether it is natural or laboratory-grown and names any detectable treatments, and can issue an opinion on geographic origin, when possible and requested by the client.
Generally, this refers to a laboratory-grown sapphire that has been manufactured with trace elements that give it a color-change effect similar to natural alexandrite. Natural sapphires can also show a color-change effect, but it is usually less pronounced.
An Alexandrite PoemAlexandrite, a gem so rare and fine, a color-changing gemstone, truly divine. In natural light it gleams a deep green hueBut under incandescent light, it turns a fiery red, it's true.
Alexandrites - A Brief History of This Color Change Rare GemstoneIn the world of gemstones, real alexandrite stone is a fairly "new" gemstone. True, it has been part of the earth for millions of years, but unlike many other gemstones, it wasn't known and used in jewelry by the ancient Greek or Romans or any ancient peoples. It was discovered in the mid-1830s in the Ural region of Russia. Some believe that genuine alexandrites were discovered after a local peasant discovered emeralds in the roots of a fallen tree which led to emerald mines being opened in the area and that led a few years later to the discovery of a new gemstone - natural color change alexandrite. The actual name of the person who first discovered this gemstone is not known, but the first person to bring it to the attention of the public was Count Lev Alekseevich Perovskii, an avid collector of minerals and precious stones and also the man who was in charge of the management of the Russian Imperial Family estates and income. It has been said that Count Perovskii turned to Nils Gustaf Nordenskijold who had an exceptional and comprehensive knowledge of gemstones, to examine the newly found mineral. It appears that Nordenskijold at first identified the mineral as emerald but he was confused by the high hardness. And, it seems that he first looked at the mineral sample during daylight hours, set it aside to look at later, and then was looking at the specimen by candlelight when he noted that the color of the stone had changed to raspberry-red. He later confirmed that the sample was a new variety of chrysoberyl. Count Perovskii, wishing to ingratiate himself further with the Imperial family, presented the rare gemstone specimen to Tsarevich Alexander, future Tsar of Russia and named the gemstone Alexandrite in his honor.
Loose Alexandrites in Modern Times Add the fact that alexandrite colors are also the colors of Russian Imperial Guard alexandrite became the official gemstone of Tsarist Imperial Russia. For many years after its discovery, Alexandrite was pretty much limited to the Imperial Family and the upper echelons of the aristocracy. Master Russian jewelers loved this stone and who knows, you might be one of the few lucky ones to come across an antique piece of Russian alexandrite jewelry. George Fredrick Kunz, Tiffany's master gemologist was also a big fan of alexandrite and Tiffany's produced some exquisite rings and platinum ensembles containing alexandrite at the end of the 19th and beginning of the 20th centuries. What Kind of Gemstone Is Natural Alexandrite? Natural Alexandrite is a Color Change Chrysoberyl. Chrysoberyl is a relatively small species of gemstones, basically consisting of 3 varieties: golden chrysoberyl (yellow, yellow-green, yellow-golden or brownish), golden cat's eye chrysoberyl, and alexandrite (which can also be cut in cat's eye cabochon). Please do not confuse chrysoberyl with the "other" beryl species that is aquamarine, emerald, morganite, and golden beryl. They are not related. Of the chrysoberyl species, alexandrite is far and away from the rarest. Golden cat's eye chrysoberyl is very popular and readily available. Chrysoberyl is a very hard gemstone, 8.5 on the Mohs scale, making it a gemstone very suitable for jewelry. Color Change Alexandrite Gems Alexandrite is truly a magical color change gemstone. It doesn't just change hues of color - say from pink to red or blue to green, but changes from one distinct color to another depending on the light source. Alexandrite will appear green (bluish-green) in daylight or fluorescent light and will turn a red, purplish-red, or raspberry red in incandescent light. Most people will never have the privilege to see an alexandrite that changes from a stoplight green to a stoplight red because they are so very rare.Gemological Characteristics of Genuine Alexandrite Gems There are other color change gemstones like garnet or sapphire but alexandrite is the only color change gemstone that actually has its own very specific and strict scale for color change and that scale will affect how an alexandrite is priced. Well cut alexandrite larger than two carats in weight can be among the most expensive and rare gems in the world and the cost can be significantly more than a diamond of the same carat weight. Alexandrite is a Type II gemstone, so clarity is also very important. The closer the colors are to green and red of a pure hue the higher the value. Secondly, the better the color change the higher the value. Either the green or red must be of a good hue. The degree of color change can only be truly evaluated with a single light source in a dark room. Traditionally a candle is the best light source to evaluate the red color! Although clarity is a significant factor in the evaluation, an alexandrite with a poor clarity rating with a 100% color change is more valuable than an alexandrite with a 50% color change and a high clarity rating. Fine quality stones over 2 carats are both very rare and very expensive. What is The Definition of an Alexandrite Gemstone Recently, the gemstone market has seen an influx of color change chrysoberyl that is being called alexandrite but it doesn't match the strict color change scale. Yes, it is a color change chrysoberyl, but in order for a gemstone to be classified as an alexandrite, it must fall in the color change from green (bluish green) to red (reddish-purple / pinkish purple). Anything else, color change from green to yellow, for example, makes it a much less expensive color change chrysoberyl. Fairly recently, there has been chrysoberyl coming from India that is a beautiful bright green, but it doesn't have any color change. It too has been incorrectly marketed at alexandrite.Unfortunately, buyers are sometimes paying alexandrite prices for color change chrysoberyl gemstones so price isn't always a good guide to what the buyer is purchasing. On the other hand, some sellers are offering what they are calling alexandrite at fantastic inexpensive prices. In that case, if it sounds too good to be true, it probably is. Always keep in mind that in order to be a genuine alexandrite a gemstone must have the green (bluish-green) to red (reddish-purple) color change. If at all possible, especially for larger (over 1 carat) alexandrite, don't purchase it unless it comes with a gemological certificate from a well known gemological laboratory. The bottom line always purchase alexandrite from a reputable seller who sells only professionally graded certified and guaranteed alexandrite. Is It A Genuine Alexandrite? Is That Heirloom Natural Alexandrite? Synthetic alexandrite has been around in some form for at least 100 years. For example, synthetic corundum (sapphire) can have an alexandrite-like color change. There is also synthetic spinel that can mimic the alexandrite-like color change. Man-made (simulated) laboratory created alexandrite has been around since the 1970's. On a sad note: since synthetic sapphire posing as alexandrite has been around for at least 100 years, a ring that has been handed down from generation to generation and that has that huge alexandrite in it, is in all probability a synthetic. Alexandrite wasn't and isn't usually found in large carat weight sizes and the ancestors would have had to have extreme wealth and/or come from aristocracy 100 years ago in order to be able to purchase a 15 or 20 carat alexandrite.Laboratory and synthetic alexandrite is available in the marketplace today and is used in jewelry, but it must be disclosed that it is manmade or synthetic. Alexandrite, Sources and Localities Where is alexandrite mined? There is virtually no alexandrite coming from Russia these days. Between 1833 and 2008, Alexandrite has been discovered not only in Russia but in Australia, Brazil, India, Madagascar, Myanmar, Sri Lanka, Tanzania, and the US. This list may seem long, but the production of top quality alexandrite from any of these mines has been relatively small. Currently, the best alexandrite comes from the Hematita mine in Brazil.
