K.V Gems is a wholesale coloured gemstone company. We specialize in unheated rubies, sapphires and spinels as well as other semi-precious gemstones from diamond-cut round melee to single pieces, pairs and layouts. We have a precision cutting factory as well as a hand-cut factory with highly skilled cutters. We take pride in working with and for our valued clients to source exactly what they desire for their high-end jewellery designs and collections. With headquarters in Bangkok, considered to be the world's leading cutting and trading hub for gemstones, we are always on top with the market sources. As a result, our family-run business has differentiated itself within a highly competitive global market. There are two defining commitments which have brought together K.V. Gems. The first was to source a truly selective inventory of only the highest quality, unheated gemstones. K.V. Gems is a labor of love and appreciative passion for untreated coloured gemstones. Established in 1984.
