Smoky, chocolate, brown matrix in Bisbee Turquoise

This is a beautiful, medium blue smoky Bisbee Turquoise cabochon. It was hand cut by John Hartman for me natural smoky Bisbee rock. It weighs 14.75.cts. We do not treat Bisbee Turquoise that, we feel, is hard enough to cut a stable, durable gemstone. We are also mindful not to use any harsh chemicals in any of the cutting or processing of our Natural Bisbee Turquoise cabochons. John & Estell Hartman have been Bisbee Turquoise since the late 1960’s. John has been cutting Bisbee Turquoise Cabochons since 1972. There is no person that has cut and studied the Bisbee Turquoise mineral near as much as John, that is a fact!
