Alexandrite, Lab Created Alexandrite 

The Gem That Changes Color

Before we get into the discussion about alexandrite gems, let us clarify the issue about lab created gems in general and lab alexandrite in particular. In the gem trade, a lab gemstone or a created gemstone is a gem that is made in a factory. In our case the name alexandrite would refer to a natural gem, the name lab alexandrite would refer to an artificial gem that imitates alexandrite. Jewelers who normally do not deal in artificial gems make an exception when it comes to artificial alexandrite, the reason for this will become clearer in the paragraphs below.

The gem Alexandrite was first found in Russia, it was aptly named after Russian tsar Alexander II. This reference is ofcourse made to natural alexandrite and not factory made imitations. The gem quickly gained importance but has until today, remained as an expensive gem, affordable by a few wealthy people. Alexandrite has a natural property that is very rare, it changes color in different light conditions, not many gems can boast of this capability. Combine this with the fact that, a very small amount of alexandrite is present in the mines on our planet and you will understand why the supply and demand equation pushes the price up. If you considered only gem quality alexandrite with clear and good color change, the rarity of the gemstone is further exaggerated.

When talking about natural alexandrite, very few gem and jewelry providers refer to sizes beyond a carat. You might see larger gems in the museums of Russia. Smaller sizes are used in highend jewelry in the U.S and Europe. Just remember that to be worth the purchase, all alexandrite gems should show color change, the more 'violent' the color change the more valuable the gem. The table below will give you an idea of the color change that you can expect from an alexandrite gem stone.

If you a bit deeper into the chemical composition of alexandrite, you would find that it is a type of chrysoberyl. Like most other chrysoberyls, alexandrite contains iron and titanium. But unlike other chrysoberyls it also contains a substantial proportion of chromium. The occurence of chromium is what gives the gem it's amazing color change property. When gemological experts strictly apply their naming conventions, it is understood that a chrysoberyl to be named an alexandrite must posess the color change property. Gem providers love to classify the degree of color change using words like mild, medium, high or violent.

Despite the fact that alexandrite is today mined in more areas than just Russia, the availability is very restricted and this supports a high price point. Brazil, India, Sri Lanka and even Tanzania are other countries where alexandrite is mined. However not many of these mines can come close to the quality of Russian alexandrite especially in the early decades. We will now move to the discussion on price as it will help us better understand why, lab alexandrite is widely accepted by gem and jewelry manufacturers. For our discussion, let us presume that we refer to a 2 carat oval alexandrite piece. It is ofcourse very unlikely that you will come across an eye clean natural alexandrite gem stone in this size. You would therefore have to accept a few inclusions that are visible to the naked eye.

A 2 carat size gemstone is not really big going by dimensions. Infact if you were talking about a mens alexandrite ring, you might need a gem that is around 50% to 75% larger than this. A natural alexandrite with fairly good (not eye clean) clarity and visible (moderate) color change, would be priced at around 2,000 U.S$ to 3,500 U.S$ per carat. So that 2 carat oval alexandrite gem stone would be priced at a hefty 4,000 U.S$ to 7,000 U.S$. Remember that this is not your complete jewel, you still need to budget for diamonds (if any) in the design and metal costs too. So your alexandrite ring with a 2 carat stone, a few accent diamonds and a gold weight of around 10 to 15 grams, could be priced as high as 5,000 U.S$ to 8,000 U.S$.

Those prices do sound scary to most of us, but that is the way things are. The Russians did one more thing to alexandrite, they studied it and analyzed it's physical and chemical properties. They then put together a team of scientists who could replicate those properties in a controlled laboratory environment. So what you get is a laboratory alexandrite, the gem trade calls is lab alexandrite or created alexandrite. This lab gemstone has the same hardness and color as natural alexandrite gemstones, more importantly it also mimics the color change property of natural alexandrite. Ofcourse inspite of all these similarities it is not a natural alexandrite but a lab created stone. Now let us throw around some price figures for lab alexandrite. A well cut lab alexandrite with good color change property, well cut and weighing around 3 to 4 carats would be priced at just 150 U.S$ to 200 U.S$. This is for the entire piece and not price per carat. So if you are doing a price tag comparison you are comparing around 5,000 U.S$ for a natural alexandrite as against, 150 U.S$ for a lab created alexandrite stone.

The fact that natural alexandrite is so rare and so very expensive, has encouraged the development and production of lab created alexandrite. Since the production of lab alexandrite is done in a factory environment, other countries have now learnt the Russian process and set up their factories. It does appear as if natural alexandrite and lab created alexandrite will continue to exist and thrive, they have carved a niche market for themselves. After all an affluent buyer with a mega budget to buy a 8,000 U.S$ alexandrite diamond gold ring, would not even think of getting a 200 U.S$ factory produced imitation for the stone. Similalry most of us who like alexandrite but are blessed with much smaller budgets, will feel glad and relieved about the lab created imitation.

There is one important thing that we would like to clarify regarding lab created alexandrite. We once got an email from a French lady who purchased an alexandrite pendant with an imitiation gemstone, from an upscale jewelry show in France. Few years later, the jewel needed some repair and the jeweler accidently scratched the gem. This apparently 'took off' the surface coating and exposed a colorless stone inside! This is NOT supposed to happen with the lab created alexandrite. The lady most probably got saddled with a surface coated imitation, such stones will lose their beauty and color change property if scratched, recut or repolished. Lab created alexandrite is produced as a homogenous mass, so the color and other properties of the gem are consistent all through the gem. But since we now know that surface coated junk is also being sold, make sure that you check the exact imitation stone that you are getting before making a purchase.

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.
