Identifying Moissanite

Because of the higher dispersion factor (ability to split light into rainbow colors) that gives Moissanite its signature fire, it can be easily identified when compared to a natural diamond. Anyone who has seen a few real diamonds would also be able to pick it in most lighting conditions as well. However to the untrained eye, it might not be so obvious. Interestingly too, Moissanite can actually fool some diamond testing machines (thermal testers) and produce a false positive. However it is safe to say that if a thermal diamond tester gives a positive result, the stone is either a diamond or Moissanite – no other stones will give the same result. It should then be a simple matter to distinguish between the two visually. In addition to the dispersion, birefraction will produce a visible difference. As mentioned previously in my article about Moissanite jewelry, birefraction is caused by the internal crystalline structure of the gem, and results in facets of the gem looking ‘fuzzy’ when viewed from certain angles. Finally, Moissanite can sometimes be identified by long thin ‘inclusions’ (imperfections) in the stone, visible under magnification.

Caring for Moissanite

Moissanite is extremely hard, close to a real diamond, so you don’t have to worry about it chipping or wearing more than any other jewelry. The metal that it is set in is more likely to become damaged than the stone itself, but sensible precautions will be enough – as with any jewelry, don’t store your rings or other pieces anywhere that they might move and scratch each other.

Moissanite jewelry can be cleaned using a any acid free cleaner. Often, soap and water and a small brush like a toothbrush will be enough to clean your jewelry. However an ultrasonic bath is another practical method.

Finding Moissanite for sale online is easy, with Amazon being a great example of a reputable supplier, carrying a range of Moissanite earrings, Moissanite engagement rings, wedding bands and sets, and other general jewelry. Here is a look at some lovely pieces that are reasonably priced, and show the versatility of this stone. It’s worth noting that Moissanite is considered a better quality stone than Cubic Zirconia due to its hardness and brilliance. It is also a more complicated process to produce the gem, and these factors are reflected in the price to some extent.

Moissanite vs Cubic Zirconia & Diamonds

Interestingly, Moissanite is harder than Cubic Zirconia, coming close to a real diamond in hardness measured on the Mohs scale, rating a 9.25 vs 8.5 for a CZ. One of the key differences is its much higher level of dispersion. Dispersion in jewelry refers to the ability of the gem to split light into it’s rainbow of separate colors. The effect of this is to give Moissanite an incredible rainbow color effect compared to other diamond simulants. This certainly makes it distinguishable from a real thing, at least to an experienced observer, but many buyers actually find this a desirable quality, with their jewelry having amazing brilliance and fire.

One of the only problems with Moissanite, and it certainly is something that can be worked around, is birefringence. This quality means that light travelling through the stone is split into separate paths, giving a slightly ‘fuzzy’ appearance to the internal lines created by the facets. This can be alleviated to some extent by careful cutting of the gem, which is one reason that a reputable dealer is worth the slight extra expense.

Production

Moissanite is Silicon Carbide (SiC, also called Carborundum), and it is easy to mass produce the mineral using a mixture of coke or coal which is electrically heated to high temperatures. This process is done on an industrial scale to produce hundreds of tons of the material for use as an abrasive. However this process does not result in a gem grade material, being instead a coarse black mass. To make a true gem grade material a more controlled growth process is required. In a similar fashion to lab created diamonds, SiC is vaporized into a gas, and then introduced to a high temperature chamber containing seed crystals of Moissanite. This process can produce large crystals in less than a day.

Buying

As with any gem, shoppers are advised that you usually get what you pay for. You may be able to find cheap or discounted Moissanite on auction sites like ebay, but be aware of the language used by some retailers and make sure to read the fine print.

This means that lab created Emerald jewelry offers stunningly clear, large stones that work well with or without other synthetic stones like lab created Diamonds.

More about created Emeralds

Emeralds are in the group of gems known as Beryl. Structurally the same apart from a small number of particles which are responsible for the differing colors, this family also includes the rare Red Beryl or Red Emerald, Heliodor and Goshenite.

Created emeralds can be produced in the lab by several different methods. The best quality lab created emeralds are made using the hydrothermal method. This method produces single, high quality crystals and works by introducing dissolved minerals to an aqueous environment under pressure and at high temperature. The temperature in the chamber is controlled so that minerals come out of solution and grow crystals over a period of days. Many different created gemstones can be produced using this method.

Cubic Zirconia was first produced in Russia for industrial use, with the intention of using it in manufacturing laser equipment. However it was quickly realized that this new material could have jewelry applications. In the 70s and 80s new manufacturing technology, which employed microwaves to melt the mineral used to make Cubic Zirconia meant that large scale production could commence. These gems are now so popular that almost every clear or colored imitation gemstone on the market is likely to be a CZ.

For the story of Russian lab diamonds we need to rewind a little to the late 40s and early 50s. Around this time at the start of the cold war, it was realized that a source of diamonds was needed that was independent of western control. Diamonds are immensely important for industrial and military manufacturing and if the supply was interrupted, this would have significant impacts on Russia’s manufacturing capability.

Joint efforts were made to discover natural sources of diamonds as well as investigate whether industrial grade diamonds could be manufactured. Both efforts met with success, and around the time the first Russian diamond mine started production, synthetic diamonds were also being produced using the High Pressure High Temperature (HPHT) method. The newly mined diamonds were quickly brought to the international jewelry market and became a valuable part of the countries GDP.

The interesting story here is that worldwide estimates of the production capacity of the new mine were exceeded, massively and over a prolonged period. The production was so great, and the diamonds of such consistent quality, that the oversupply threatened to destabilize the world price of diamonds for a time. In the 70s, Scientists realized that some of the diamonds coming out of the country were in fact synthetic. Russian officials claimed that it was not cost effective to produce these for gemological use but it is interesting to speculate that some new technology was discovered and some percentage of the diamonds sold were in fact Russian man made diamonds.

The footnote to this story is that the present volume of Chemical Vapor Deposition (CVD) diamonds which are being produced in the US owe their technology to Russia. One of the founders of Gemesis is said to have sourced his equipment from a Russian government bureau which was tasked with selling Soviet technology. As we know, diamonds produced by the CVD method are substantially cheaper than HPHT diamonds. The question must be asked – exactly when did the Soviets perfect the CVD technology. We may never know… but it is fascinating to speculate how many of the sparkling diamonds on the fingers of European socialites over the last 50 years were actually made in a Russian lab!

Sapphire

Let’s take a look at true lab sapphire. This is made of corundum as is the naturally occurring stone. In fact, it is created from a powder of real sapphire, so that is about as close as you’re ever going to get to the real thing. The good thing, of course, is that this will cost you much less than the real thing. If not for that, I suppose there would be no market for lab created stones.

Ruby

Now, lab created ruby can also be very beautiful. Like its predecessor it is made out of corundum. Those who love the passionate color red will have to take a second look at this first-rate creation, as it looks and feels essentially just like a real ruby. It is very stunning, and as always you can save a lot of money going this route. (Not that anyone ahs to know that!)

Emerald

Finally we come to emerald. This is a member of the beryl family as all lovers of the color green will likely already know. One good thing about going with the lab created emeralds is that they typically have a higher degree of perfection than is normally found out in the wild. This is really one of the unsung reasons to choose synthetic other than the price. Of course, you will find that it is made of the same materials composed in the same way too.

Keep in mind that all of these pieces are literally grown in a lab, and as such can be subject to the ever-watchful eye of their overseers. This degree of attention has created some truly brilliant lab created stones over the years, and will doubtless continue to do so. There is no better way to get to wear the “real” thing without having to pay for it. Every color and gem can be represented so exquisitely that everyone you know will truly be impressed.
