How Moissanite Jewels Work | HowSfWorks
More than a century later, Cree developed a process for producing large, single crystals of moissanite. In 1995, a master diamond cutter observed samples of the silicon carbide crystals and suggested to the founders of Charles & Colvard that, if properly cut, the crystals could make a beautiful jewel.
Jeweller’s Bench Guide – Moissanite SA
If a buff or silicon wheel of any type is used, it must only be used on the metal. If it touches the pavilion of the stone, it will remove some of the colour treatment. Because of the nature of these stones, it is strongly recommended that the mounting be polished before the stone is set, so only the tips of the prongs need a light polish with a felt wheel.
