Listed is a set of four treated and stabilized 10 x 14mm rectangular Kingman turquoise cabochons. These are very fine, gem-grade cabs, processed by the Colbaugh Company in Arizona. This is some of the best, finest cut turquoise you can find nowadays. I have a few sets of these, but I put each set together to match as well as possible on color and matrix distribution in each cab.
