![]() The matrices and tilt views of these maps permit one to find the stones that perform best in terms of illumination properties. The maps we introduce are a valuable educational tool, provide a basis for gemstone grading, and are useful in the jewelry industry to assess gemstone performance.ĪB - We discuss several illumination effects in gemstones and present maps to evaluate them. ![]() For the first time it is clearly shown why the Tolkowsky cut, and other cuts adjacent to it along the main cutter's line, is one of the best round brilliant cuts. By using the concepts of the main cutter's line, and the anti-cutter's line, the problem of finding the best stones is reduced by one dimension in the cutter's space. N2 - We discuss several illumination effects in gemstones and present maps to evaluate them. If you want whitest stones available, you can upgrade to Forever One moissanite, which is significantly whiter and can match the color, cut and clarity of the highest quality diamonds.T1 - Evaluation of brilliance, fire, and scintillation in round brilliant gemstones Their Forever Brilliant™ moissanite can have slight hints of yellow or green, which is barely noticeable, even when mounted on white gold. You can enjoy the brilliance and fire of moissanite for a lifetime with absolutely no maintenance other than the occasional cleaning.Ĭharles and Colvard is the first global provider of moissanite. It is neither porous like cubic zirconium, nor attracts oil and dirt like a diamond. Unlike other brilliant stones that cloud and dull with time, moissanite is guaranteed to never lose its optical properties. It is now available as beautifully faceted gemstones in a wide array of different shapes and sizes. There is so little naturally-occurring moissanite that there isn’t enough to make a pair of earrings therefore all moissanite used in jewelry has to be meticulously lab-created. Moissanite was first discovered in minute quantities from particles carried to earth by a meteorite thousands of years ago. Overall, moissanite is not only an earth-friendly substitute for diamond, it is arguably a better gemstone than diamond for creating spectacular fine jewelry that will last a lifetime. ![]() Just like diamond, it can be cast into intricate jewelry designs because of its resistance to high temperatures. Composed of carbon and silicon, the moissanite crystal is one of the hardest and toughest known naturally occurring minerals, making it extremely resistant to scratching, chipping and breaking. Possessing fire, brilliance, and luster that surpasses even that of a diamond, moissanite twinkles, and sparkles unlike any gemstone on earth. That means that even under 10 times magnification, you will be hard-pressed to find any flaws inside the stone. ![]() All of our moissanite has a clarity rating between VVS1 and VVS2, just shy of a flawless rating. The fewer inclusions a stone has, the better the light can dance around inside the stone and back to your eyes. The clarity of our moissanite is second to none. Then we hired a team of highly skilled stone cutters who know how to turn moissanite rough into beautiful works of art. We have searched the world looking for the whitest and clearest moissanite rough manufacturer, and we found them. Harro Gem is also an over-achiever in color, cut, and clarity as well. Whatever the case may be, we will have the perfect solution to meet all your unique gemstone needs. Are you looking for a pair of colorless trapezoid side stones to go with your 5-carat emerald Harro Gem centre stone? Do you need an 8.25mm Old European Cut to fit an antique ring, while every other moissanite provider is either cutting an 8mm or an 8.5mm? Maybe you found the perfect stone somewhere else but have been on their wait list for over a month with no indication as to when you will receive the stone. If there is a shape that we don’t have in stock, we can custom cut a moissanite stone just for you. You can even order a cushion and oval with either a brilliant cut or a crushed ice cut. The cushion can be made in a pillow cut (rectangular), Jubilee cushion cut, Hearts & Arrows, or Old Mine Cut. Just for the round cut alone, Harro Gem has a variety of different cuts, such as the Hearts & Arrows, Belgium cut, 100 Facet Starburst, Old European Cut, Jubilee Cut, and Rose Cut. Colorless moissanite typically comes in common shapes, such as round, square, cushion, and oval. Just like diamonds have the “4 C’s”, moissanite can also vary in color, clarity, cut, and carat Harro Gem has one more “C” up its sleeve: Choice. However, not all moissanite is created equal. Harro Gem is a premium moissanite made from silicon carbide (4H crystalline polytype version), the same material as the Forever One by Charles and Colvard.
