RARE AAA+ Blue Ridge Turquoise (Nevada) 2.5mm Round Beads, 16 Inch Strand
These have been stabilized using the Zachary treatment method. The Zachery treatment is a proprietary, non-toxic process developed in the 1980s that enhances turquoise by reducing porosity, increasing density, and improving color and polish. Unlike plastic stabilization, it does not use dyes or resins, but increases potassium levels, making the stone more durable and resistant to oils.
The Blue Ridge turquoise mine, also known as the Orvil Jack mine, is a notable Nevada Mine in Lander County (Crescent Valeey) discovered in 1956. It is famous for producing high-quality, translucent blue nuggets with dark matrix and, from the 1980s, unique yellow-green, zinc-rich "Orvil Jack" turquoise. It is highly prized for its color variation.
