Would strongly suggest lapidary person who also knows and does setting and jewelry making as well. That person is who is a master brazlian cutter who also cuts opals and many other stones both faceting, fancy facetiong, carved cabs , jewelry carvings , ext Gerson Bispo of Miami Flroida . His phone is : 304-417-3245
Mr Bispo has overseen cutting facilities in India, Hong Kong, Brazil and in the USA. He is an extremely skillful gemstone cutter and lapidary artist having cut many different stones including opals and all set many stones as well. He also is known for jewelry carvings and heat treatments of gemstones and other treatments as well having worked with irradiated as well as other treatments in gemstones.
I would highly recommend him as many club cutters or others may not have the experience nor the ability of cutting opals or other kinds of gemstones.
