It began more than 120 years ago, during a search for efficient electrical conductors, when Nobel Prize-winning chemist, Dr. Henri Moissan, discovered moissanite (silicon carbide) in a meteorite crater. He resolved to find a way that science could reproduce this remarkable yet extremely rare mineral, which held such promise. Fast forward a century. After years of experimentation, certain researchers from the Research Triangle Park in North Carolina developed and patented a process for creating pure silicon carbide (SiC) — a long-sought-after breakthrough, which made possible significant advances in the development of diverse products that included semiconductors, LED lighting and extremely hard drilling tools and abrasives. And now the vision and innovation of Charles & Colvard could be fulfilled. With hardness rivaling any mineral on Earth, and refractive properties exceeding that of a diamond, moissanite was a brilliant new type of gemstone, free of environmental and ethical issues – and capable of disrupting traditional definitions of fine jewelry. We continue to perfect and innovate with our jewelry. Just as important is making products that exceed expectations, and offering service that goes beyond the transaction. We always remain true to our pioneering roots, operating with integrity and transparency and using our business as a force for good. We’ve been creating moissanite for over 20 years. Not just making, but tirelessly refining and improving. Generating better products and developing better techniques for cutting and polishing. In short, doing everything we can to enhance the stunning brilliance of this amazing stone.
