John Hartman & Estell Hartman have collected Bisbee Turquoise since the late 1960's. John has been cutting Bisbee Turquoise since 1972. There is no person or company that has cut and studied Bisbee Turquoise or this Mineral near as much as John, That is a fact!!!
We do not treat Bisbee Turquoise that, we feel, is hard enough to cut a durable, stable gemstone. We are also mindful not to use any harsh chemicals in any of the cutting or processing of our Natural Bisbee Turquoise Cabochons.
Treated / Stabilized Bisbee Turquoise-
We only use a water based solution to achieve a harder material that will provide much longer durability in a piece of finished Jewelry. This is a good thing!
