This category is for suppliers of loose gemstones, pearls, and gemstone rough used to fabricate finished jewelry. Vendors listed here sell individual stones, or in small lots, online to the general public.
Cabochons (cabs) are gemstones polished to domed, rounded or free-form shapes rather than "cut" with flat facets. Suppliers here provide hand or machine polished cabochons and include individual lapidary artists and larger suppliers who sell to the general public.
Faceted gemstones are those cut and polished with geometrically regular, light-reflecting, flat faces - facets.
Online suppliers of faceted gemstones as well as individual lapidarists ("cutters") specializing in faceting services are listed here. These suppliers sell loose individual stones, or in small lots to the general public.
Opals are semi-precious stones that are luminous and iridescent, frequently with multi-colored inclusions caused by entrained water ("fire"), and are finished as cabochon.
Sources listed here include miners, individual lapidarists, and online retailers of opal gemstones and rough selling individual stones, or in small lots, online to the general public.
Rough or slab is gemstone material in its natural state prior to cutting, finishing, polishing or faceting. Suppliers in this category are often miners, individual lapidarists, or firms closely connected to mining operations, who sell online to the general public.
Rough is often further described as either facet or cab depending upon its suitability for finishing - facet rough being typically translucent with minimum impurities, and cab rough being generally opaque.
