Custom cut gemstones

An essential part of our service is custom gemstone cutting. You may supply rough stones for us to have precision faceted or cabbed into the shapes that you desire. In addition, many gemstones that are already native cut will be improved in clarity and light return by a new precision cut.

Custom orders on gemstone cutting are normally ready in just two to three weeks. Message me with details of your gemstone requirements. I will provide the address along with special instructions on shipping stones to us.
