The KGK Group invests in primary gemstone mining in South America, and Africa. KGK gemologists and engineers extract a rang of highly desirable exotic colored gemstones including Emeralds and Rubellites. In addition to our own mines, we source an exceptional range of precious and semi-precious gemstones alongside cutting and polishing the same, in order to serve our jewellery. The KGK Group is among the key global companies to partner with Gemfields & Fura, the world’s leading suppliers of the responsibly sourced colored gemstone.
