We use only the highest quality rough. We cut each individual gemstone perfectly. Swarovski Marcasite is the most brilliant marcasite available on the market, with a beautiful and unique metallic luster. Thanks to Swarovski’s exceptional expertise and innovative technology, our precision-cutting techniques bring out the best natural qualities from every single stone. Marcasite is both an elegant and fashionable gemstone. The mirror-like surface and shimmering finish of Swarovski Marcasite make jewelry elegant, fascinating and precious. The shape, proportions, and exact cut are optimized to provide a perfect, reflective surface. Our polishing techniques give each gemstone an elusive, metallic sheen and a characteristic sparkle. The surface polish of precision-cut Swarovski Marcasite sets it apart from hand-cut stones, which are subject to the risk of oxidation.
