Natural mined diamonds have been coming under a lot of heat recently. Award-winning journalist Cecil Adams sums it up the best in a recent article: “diamonds are a scam, pure and simple.” Most people in the new millennium understand that between the DeBeers diamond cartel, the issue of child labor in Third World diamond processing operations, and “blood diamonds” used to finance oppression and genocide in Third World African countries, not to mention your snooty and pretentious local jeweler, diamonds are just not worth the hassle, guilt, and let’s not forget thousands and thousands of questionably spent dollars.

Lately, new synthetic diamonds have come on the market that have all of the look, appeal, and glittering beauty of natural diamonds, but without the baggage, and at a fraction of the cost.

Since moissanite burst upon the scene in the late 90s, it has created quite a stir. Moissanite is gem-quality silicon carbide. The production of moissanite is a proprietary process and it is available only from C3 Inc, a division of Cree Research.

When moissanite was first introduced to the market it created a great deal of publicity. This was due to the fact that moissanite would often fool a jeweler into thinking it was a natural diamond. Both the Nova and 20/20 TV news shows did segments featuring hidden cameras showing jewelers fooled and embarrassed by moissanite. What was actually happening though was not quite so simple.

Jewelers generally rely on something called a “thermal-probe” to detect a fake diamond. Thermal probes work well with cubic zirconia, for instance. Moissanite, however, has a thermal conductivity that is very close to diamond. They were able to fool the older thermal probes. The fact of the matter is though; moissanite really just does not look that much like diamond. The two substances have radically different optical properties. These differences are clearly visible to the naked eye. It was obvious in both the Nova and 20/20 segments that the jewelers were clearly confused. They kept looking at the stone and then testing at and saying things like, “Well, I guess it must be real.” What they were really saying is “Well, I guess it must be real, but it sure is a weird looking diamond!”

Problems with Moissanite as a Diamond Stimulant

Anisotropy
Unlike natural diamonds, or some of the better quality synthetic diamonds like those available from Diamond Nexus Labs, (http://www.diamondnexuslabs.com) moissanite stones have an optical quality known as “hexagonal polytypic.” What this means is that moissanite is doubly-refractive. And because of this they create a strong visual effect known as “birefringence.” This is visually seen as a doubling of the stone’s back facets that creates a marked “drunk-vision” effect.

Dispersion
Moissanite has a dispersive power nearly 2.5 times greater than that of diamond. This creates what’s known as the “disco-ball” effect. Some think that this excess fire is beautiful; others think it cheap and fake looking.

Color
It is impossible to produce a pure white moissanite. The stones have a quality known as “fluorescence” that causes them to appear slightly green or gray. This effect is much greater under natural light. In the jewelry store a moissanite dealer will always show the stones under a pink tinged light, as this tends to cancel out the fluorescence. Many people say they loved their moissanite ring until they got it into the sunlight.

Cost
Due to its relatively extensive manufacturing process and the fact that it is only available from one source, moissanite tends to be quite expensive (though still cheap when compared to diamonds) good quality moissanite stones run around $520 per caret.

Better Synthetic Diamond Alternatives
In the last two years there have been almost miraculous breakthroughs in the science of synthetic diamond creation. There are several new processes that create gemstones that are virtually indistinguishable from natural diamonds. One of the best I have found are the gemstones available from www.DiamondNexusLabs.com. I recently did independent research for several synthetic diamond companies and found their products to be among the best.

Diamond Nexus gemstones cut glass, they have brilliance, dispersion and radiance factors that are very close to mined diamond, and best of all, as they are new in the US market, they are priced at an incredible $79 per caret. This is a bargain that probably will not last.

Conclusion
Moissanite stones are beautiful in their own right. They offer great sparkle and flash. However, if you truly are trying to purchase a gemstone that comes as close as possible to the properties of a natural diamond moissanite is not the best choice.

They say that diamonds are a girl’s best friend, and diamond rings are definitely no exception! Rings in general are a girl’s dream. Starting with promise rings from a first love. Then, there’s the class ring that even guys love to call their own. And of course, the beautiful diamond engagement rings that all girls dream of. Well, yes, some of us can fit belly button rings and even nipple rings into our life lessons. But, whatever the type, whatever the reason, everyone can admire a beautiful ring.

It is easy to go to any retailer these days and find rings of all shapes and sizes. Even discount stores, like Walmart, sell jewelry. But, finding quality items takes you to your local jeweler. If you are in the market for precious gems and jewels, consider finding an experienced, honest jeweler.
A basic knowledge of diamond rings, for instance, will benefit the average person who plans to purchase one. Using diamond rings is a good example. When choosing the right ring, you will want to consider many characteristics of the individual who will be wearing it as well as the characteristics of the diamond itself. There are many types of cuts, or designs, of diamonds. Full cut or single cut? These terms are a description of how many facets, or polished surfaces a diamond has; 58 in the full cut, only 16 or 17 for the single cut. Also to consider with diamonds is the brilliance of the stone (white light reflected back from a diamond). Carats, or the weight of the diamond is to be considered as well. Then you have the type of cuts, like princess cut, and even the clarity to think about.

With so much to think about when purchasing any ring, you should do some research and investigating to determine what is the right one to purchase. It shouldn’t just be about what looks nice, but what is available in your price range and what is the quality desired. Do some research to allow yourself the opportunity to find what you really want. Doing this research online, will also benefit an individual in that it can be done from home, on your time, with unlimited possibilities.

Whatever you choose to buy, make sure it is of the quality and character that you are paying for. There are many beautiful items to choose from, so take the time to research your options.

High quality man made diamonds are a bargain at about $80 per carat, and they do not increase in price exponentially as carat weight increases. For example, a one-carat synthetic diamond costs about $80; a three-carat man made diamond would then sell for $240. A one-carat mined diamond that sells for $3000 would go for $45,000 in a three-carat size, all things being equal, which with mined diamonds is never the case. Perplexing comparative evaluations, exponential price growth, consumer confusion, and the reality of diamond industry antics is why the mined diamond business is awash in dirty tricks. Here are descriptions of the most sneaky and pervasive mined diamond scams:

THE BLUE-WHITE SCAM: A jeweler tells you, “This is a blue-white diamond.” This is a very old term. The dealer will probably tell you that it is a better diamond, but actually it is just the opposite. Blue-white refers to the fluorescence that results in natural light, which contains ultraviolet wavelengths. This blue fluorescence actually makes a colorless diamond look a little oily or milky in sunlight and decreases its value.

THE LIGHT MAKES WHITE SCAM: Bright lights make every mined diamond look better. Of course, every jeweler wants to show his or her diamonds in the best light, but there are some lighting tricks you should avoid. Some bulbs have a strong blue component, which makes yellow stones look whiter. Special bulbs are often used with strong ultraviolet wavelengths, which make most diamonds fluoresce blue. This also has a whitening effect for stones in the lower color ranges.

THE GRADE BUMPING SCAM: A jeweler exaggerates the grade. The FTC says that a jeweler must be accurate within one grade of color and one grade of clarity on a diamond. So many jewelers bump the color and clarity just one grade. Unfortunately, this can mean a great deal of money if you are talking about a fine-quality, 1-carat diamond. For instance, you might find a stone that the jeweler quotes as a 1.00 carat F color / VS1 clarity for $6,500. However, if you sent it to a reputable gem lab like GIA, it would come back as a G color / VS2 clarity, which is only worth about $5,500. This means you lose (and they profit) about $1,000.

THE FRACTION SCAM: The tag says 3/4 carat, and the FTC allows jewelers to round off diamond weights. So a diamond labeled as 3/4 carat in weight might actually weigh anywhere between .69 and .81 carat. This could mean a significant amount of money, since diamond prices leap at certain popular sizes. In this example, you might be buying a .69 carat round G/VS2 worth about $2,100… but paying for what you thought was a 0.75 carat worth $3,000. You lose $900.

THE LASER DRILLING SCAM: Dealers drill holes to burn out black carbon spots. About 1 in 3 diamonds in the United States is laser drilled. Dealers use lasers to drill a tiny hole into the depths of a diamond to burn and evaporate large black inclusions to make them disappear. The trouble with this little trick is that laser drilling can make the diamond a little more fragile to breaking with a good knock. Most dealers trade laser-drilled stones for much less.

THE HIDING THE FLAWS SCAM: Every jeweler hides flaws under the prongs if he can. In many cases, this can make an I1 clarity appear like a VS2 if you look at it in a ring setting. Structural flaws like feathers and cleavages can be damaged by the high pressure exerted by the prong on the diamond to hold it snug in the ring.

THE FRACTURE FILLING SCAM: New treatments to make flaws invisible. There is a new process patented a few years ago that melts a kind of crystal into surface-breaking fractures in a diamond. This technique will slide by consumers unnoticed. The treatment is considered slightly fragile because it can be damaging under the extreme heat of a torch when the diamond is set into a ring. Fracture-filled diamonds should trade for much less than diamonds without this treatment, but in reality they often sell for as much or more because they look like a higher, more expensive clarity grade.

THE CHEMICAL COLOR COATINGS SCAM: A little paint goes a long way. This very deceptive practice involves a little point of blue or purple paint on the lowest tip of the diamond, called the culet. This is small enough that you might not detect it, but the location spreads the color throughout the stone. This counters the yellow tint in lower color grades, making a diamond look like a more expensive, colorless grade.

Man made diamonds or synthetic diamonds are manufactured in a laboratory under controlled conditions. If anything about synthetic diamonds is called into question it is that they are too perfect. And since all mined diamonds have inclusions, flaws, and birthmarks, under magnification a trained jeweler can tell the difference. Considering that man made diamonds cannot be distinguished with the naked eye, lab-created diamonds have aesthetic beauty matching—often besting—mined diamonds, and huge savings are realized, jewelry lovers must regard synthetic diamonds as an intelligent option. Plus, there is no insurance to buy after purchasing man made diamond jewelry and the thousands of dollars in savings can be banked!
