Natural Alexandrite Gemstones  

The Rare Chrysoberyl With Color Change Properties        

Alexandrite is one of the rarest gemstones on our planet. This is ofcourse talking about natural alexandrite and not man made lab alexandrite. This gem stone is a type of chrysoberyl and a very special type indeed. Alexandrite exhibits a color change when the light conditions change, this is a very rare phenomenon in the world of gemstones. The high price levels of natural alexandrite is due to two clear reasons. The first reason is that alexandrite gems are very rare, most gem quality alexandrite is mined in small sizes. Another reason for the high price of this gemstone is due to it's color change property.

If you see a natural alexandrite gem stone in normal daylight, it appears greenish or bluish green in color. Move the same gem stone under an incandescent light and it amazingly changes color to a reddish or purplish red color. You might also come across alexandrite stones that change color to a raspberry red. Gemological experts agree on on one thing and that is alexandrite, needs to show a visible color change to be called an alexandrite. What you need to understand is that, all green or bluish green chrysoberyl cannot be classified as alexandrite. It is the color change property of such chrysoberyl that gives the gemstone the distinction of being alexandrite.

So what defines the quality of a good alexandrite gem stone, once again we would like to remind you that this discussion is limited to natural alexandrite gemstones only. Like most other gems clarity and lack of inclusions or limited inclusions, would imply a good quality alexandrite gem stone. The degree of color change that the alexandrite exhibits will also influence the price. The clearer the color change phenomenon, the more valuable the alexandrite. Gem experts like to use the terms, slight, medium, good and vivid or violent when talking about the degree of color change in an alexandrite gem stone.

Studying the size of alexandrite gem stones makes an interesting subject. Most of the alexandrite stones available in the gems and jewelry markets are of the below 1 carat size group. The fact is that alexandrite gems that weigh a carat or more, are very expensive and extremely rare. It is therefore a good idea to use alexandrite as an accent stone unless, you have a hefty budget allocated to your jewelry purchase. Just to give you an idea, a 2 to 2.5 carat alexandrite that shows medium color change, could cost as much as 2,500 U.S$ to 4,000 U.S$ per carat. It is the high price as well as the rare nature of larger alexandrite pieces, that has limited the demand for alexandrit stones in the 1 carat and beyond size range.

Rarely is a gem stone blessed with so many good features like the alexandrite. This gem stone boasts of a hardness rating of 8.5 making it suitable for all jewelry applications. It does not need any special care or fussing, you could say that it is expensive but gives great value for the price paid. The gem was first mined in the Urals in Russia, and is named after the Russian tsar Alexander. An interesting thing about alexandrite and Russia is that, the green and red color exhibited by the gem stone also happened to be the principal colors of Imperial Russia. It is therefore no surprise that the Russians have the Alexandrite gem stone close to their hearts.

The Russian alexandrite mines do not yield much of alexandrite these days. Other sources have been located for alexandrite in Brazil, Madagascar and also in the African nation of Zimbwabe. The Indian region of Orissa also outputs some fine alexandrite though, the size is generally in the half carat or smaller size. Alexandrite is a favorite among many gem and jewelry lovers, it is also one fo the most interesting gems adored by serious gem collectors and enthusiasts.

We would like to say something about lab alexandrite. This stone is not natural alexandrite and is produced in a factory. The advanced process used to make lab alexandrite or lab created alexandrite as it is known, is able to mimic the chemical and physical properties of natural alexandrite. This does mean that the color change phenomenon is also seen in lab created alexandrite gem stones. The area where lab created alexandrite really outdo their natural counterpart, is in terms of size. You can get these artificial lab created alexandrite gems in sizes that go beyond 10x8mm or 11x9mm too. These big sizes in natural alexandrite will either be impossible to find or will, cost a substantial fortune to purchase. Lab created alexandrite gems are very much cheaper than natural alexandrite gems.  

Some birth stone charts list Alexandrite as one of the birthstones for the month of June. However the high price of this rare gem, has encouraged many people to use the alternate June birthstone which is moonstone or pearl. If you are very particular about birthstones, and needed the June birthstone, you could get a moonstone ring and use natural 3mm to 4mm alexandrite stones as accent gems.

At Directstones, you can order just a single piece or as many pieces that you need. We handpick and custom cut just about every gem stone on this planet and alexandrites are just one of them. We provide both lab created alexandrite and natural alexandrite. You can choose the size and shape of the gem and even request for a complete jewel to be custom made according to your requirements. Directstones is an online gem resource maintained by the Kaisilver and Kaijewels group, the leading online custom jewelry providers with a global reputation.


Who Is Kaisilver?

Having established itself as the world's leading online custom jewelry provider, Kaisilver now extends it's merchandise line to include gems. While there is no shortage of gem stones in the global market, reliable sources for the retail buyer requirements are not many. Most retail gem dealers work with limited inventories, this reduces buyer options. Another problem with these small dealers is the lack of information and reliability when it comes to gem authenticity and value for money. Kaisilver with it's wide network of gemstone mining and manufacturing resources, is the best source for gems of all types, shapes, sizes and cuts. With a support team that is compromised of jewelry and gemstone experts, the advice and suggestions made by the team relate to your requirements and not to fixed sales targets. The website shows a small sampling of the gems that we offer. You can infact request for just about any gem on the globe. All gems are sourced directly from the source, closely inspected and then custom cut by our expert cutters. With a buyer base that includes fashion models, government officials, casino and resort owners, lawyers, financial experts, students and professors, doctors and surgeons, sportsmen and newsreaders we have become the preferred choice for quality gems and jewelry. By cutting out middlemen commissions and multiple agents, we provide great value for your money. Our large online operation does not stop us from welcoming even the smallest order. Gold and silver jewelry is custom made with equal attention to quality, material and craftsmanship. You can choose from our designs or send us detailed for the style and design that you need.


How To Order?

The process to order gems and custom jewelry at Kaisilver is similar. We do not expect you to make a rush purchase. We do wish that you take the time to discuss your requirements with our experts. They will be in a position to provide constructive suggestions that will guide you to make well informed buying decisions. Email all your requirements to provide as much inputs as possible to help us make relevant suggestions. For example if you are keen on getting a green gemstone but, are not particular about it being an emerald mention this in your email. Our gem experts might suggest a green tourmaline or even a peridot instead of an emerald. This suggestion would reduce our profit margins but will give you a gem that, is much cheaper and even more durable as compared to an emerald. When it comes to payments we offer some very suitable options. Paypal is the preferred form of payment, it is fair to the buyer and seller. The buyer when using paypal never needs to reveal credit card of bank information to the seller. We also accept direct bank transfers but prefer to do this on a case by case basis. When it comes to online transactions these days, both buyer and seller are afraid of frauds. It is quite possible that you do not feel comfortable working with us at Kaisilver. We sometimes feel a little uncomfortable with certain transactions too and prefer to keep away from them. There have always been fears of processing payments through Western Union money transfers. With the latest fraud reports, fake sellers and even fake buyers have been pulling off many online frauds using this mode of payment. At the same time we do understand that armed forces from the U.S who are stationed in various global positions sometimes have no other mode of payment besides Western Union. We therefore accept this mode of payment but at the same time, request you to avoid this mode if you do not feel comfortable using it. Shipping is done through FEDEX and you can expect a production lead time of around 4 to 5 weeks from the date of order confirmation and receipt of payment. Every jewel is fully custom made and requires the complete attention and concentration of highly skilled craftsmen. When it comes to gems, we could provide faster lead times and this can be discussed for each specific order.
