Natural mined diamonds have recently come out from under the heat. Award-winning journalist Cecil Adams sums it up best in a recent article: "diamonds are a scam, pure and simple." To understand the majority of people in the new millennium, between the De Beers diamond cartel, not the problem of child labor in Third World diamond processing and "blood" diamonds used to finance oppression and genocide in countries Third World Africans, not to mention his haughty and pretentious local Diamond jewelers are not only worth it, and do not forget the debt, spent thousands and thousands of dollars questionable.
Lately, new synthetic diamonds on the market that all the looks, charm, beauty and sparkling natural diamonds have come, but without the baggage, and at a fraction of the cost.
Since moissanite burst on the scene in the late 90s, has certainly caused a stir. Moissanite is gem-quality silicon carbide. The production of> Moissanite is a proprietary method, and it is only from C3 Inc, a division of Cree Research available.
When moissanite was introduced on the market has created a lot of publicity. This was due to the fact that moissanite is often thought to fool a jeweler, was a natural diamond. Both the Nova and 20/20 TV news, the segments with hidden cameras showing jewelers fooled and embarrassed by moissanite loose. What waswas not so simple.
Jewelers are generally based on a so-called "thermal-probe" to detect a fake diamond. Thermal probes work well with cubic zirconia, for example. Moissanite, however, has a thermal conductivity that is very close to diamond. It could fool the older thermal probes. The fact of the matter is though, moissanite really just does not see as much as diamonds. The two substances have radically different optical properties. ThisThe differences are clearly visible to the naked eye. It was evident in both the Nova and 20/20 segments that the jewelers were clearly confused. He looked at the stone and then test and said things like, "Well, I think it must be real." What it actually says "Well, I think it must be real, but it's certainly a weird looking diamond!"
Problems with Moissanite, a diamond stimulant
Unlike natural diamonds, or some of the best qualitysynthetic diamonds like those available from Diamond Nexus Labs (http://www.diamondnexuslabs.com) moissanite stones have an optical quality known as "hexagonal polytypic." This means that moissanite is doubly refractive. And why create a strong visual effect known as "birefringence." This is visually a doubling of facets back of the stone, which has seen a marked effect "drunk-vision" has been created.
Moissanite has a dispersive poweralmost 2.5 times larger than the diamond. This creates what is known as "disco ball" effect. Some think that this excess fire is beautiful, others think he is cheap and false looking.
It 'impossible to produce a pure white moissanite. The stones have a quality like "fluorescence", the causes in which they appear slightly green or gray-known. This effect is much greater under natural light. In jewelry moissanite dealer will always save the stonesin a light pink color, like these usually raise their fluorescence. Many people say they loved their moissanite ring until it got to sunlight.
Thanks to the manufacturing process relatively large and the fact that it is only available from one source, tends moissanite is very expensive (though still cheap compared to diamonds) are pretty good quality moissanite stones of about $ 520 per carat.
Best Synthetic DiamondsAlternative
In the last two years there have been almost miraculous advances in the science of synthetic diamond creation. There are some new processes, the precious stones that create little to natural diamonds. One of the best I've found precious stones are available http://www.DiamondNexusLabs.com. I recently independent research for several synthetic diamond companies and found their products are among the best.
Diamond Nexus gemstones cut glass, are factors of brilliance, dispersion and transmission, which are very close to mined diamonds, and best of all, because they are new to the U.S. market, have an incredible $ 79 per carat prices. This is a deal that probably will not last.
Moissanite stones are beautiful in themselves. They offer high brightness and flash. However, if you try really a gem that is as close as possible to acquire ownership of natural diamonds> Moissanite is not the best choice.
