Cutting is an important factor that affects the quality of moissanite drill in its classification. It determines the flash, brightness and fire color of the moissanite. Circular cutting, also known as bright cutting, is one of the most expensive cutting methods for raw stones and requires high cutting technology. The round moissanite can best reflect the fire color of the moissanite, and can reflect the light entering the moissanite to the greatest extent to achieve the brightest effect. This kind of cutting has a long history. Over the centuries, Marcel Tolkowsky made it the best in 1919, with 58 sections (33 at the crown, 24 at the pavilion, and 1 at the bottom).
