KEN's cut

Mr. KEN is a polishing craftsman living in America. I started my career in 1974 polishing opals, agates, and jade. His unique cut designs were created while cutting the agate, jade, and mossish stones he handled in the early days, and he specializes in geometric designs and concave cuts using lasers.

Mr. KEN mainly handled jewelry for the American market, but after meeting Koyama, the representative of KARATZ, at an American jewelry exhibition, he began making various cuts for KARATZ. Mr. KEN himself has a collection of old stock Oregon sunstones and Montana sapphires, and his cut pieces are exceptionally beautiful.
