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.
