How can they claim that moissanite is “rare”when silicon carbide is a very common abrasive?
Abrasives formed of silicon carbide powder are inexpensive to manufacture. Large single-crystal silicon carbide is extremely difficult to produce. Charles & Colvard have U.S. and international patent protection for moissanite jewels. top^ Clarity of Moissanite Moissanite is not separated into grades (like diamond) because its manufacturer has set strict specifications that each stone must meet before being released to distributors. Those specifications are comparable to diamonds which have been graded VS1-VS2 (Very Slightly Included – Minor inclusions somewhat easy to locate at 10x magnification). top^ Visit our affiliate’s websites! http://www.thepearloutlet.com and http://www.thepearldoctor.com top^ Red Box Diamonds – Guaranteed Value When you are ready to upgrade your Red Box Diamond, we can help by offering a phenomenal Trade-Up Program.
