===Faceting=== {{main|Faceting machine}} Faceting requires equipment allowing for very precise adjustment of angle and location around the gemstone for facet-placement, a process sometimes referred to as indexing. The design may be computer-generated or left up to the skill and expertise of the individual cutting the gemstone. During the process of grinding, faceting, and lapping, the gemstone is usually affixed ("dopped") to a rod (frequently referred to as a "dop" or "dopstick") made of wood, or perhaps brass or steel, with [[dopping cement]], a specialized [[thermal adhesive]]. The dopstick can be hand-held or inserted into the indexing equipment for more precise faceting. A [[coolant]] then needs to be constantly applied to prevent softening of the cement. Diamonds, however, are held mechanically, or with low-[[melting point]] [[solder|tin-lead solder]], since the resultant heat generated by friction can be extreme, thus preventing the use of [[thermal adhesive]]s. [[Cabochon|Cabochons]] - smooth-shaped gemstones without facets such as [[jade]] or [[turquoise]], and indeed most gemstones - are instead shaped and polished in much the same manner. They are usually left up to the skill and expertise of the individual cutting the gemstone and to similar equipment such as the [[lapping]] equipment.
