Beautiful rough Ithaca Peak Slabs hand cut by John Hartman. Many years ago I bought some rough at the peak Turquoise from the Colbaugh’s of the Kingman Turquoise Mine. I cut a lot of beautiful turquoise County Shawn from the material. The cabochons with iron pie right in them were the most popular stones I cut from this material. This 100 g lot has a great amount of iron pyrite in it and I consider it the best lot of the bunch that I have. It is stabilized as is most of Kingman Turquoise.
