Golden Tiger’s Eye, sometimes called Yellow Tiger’s Eye, has a Trigonal crystal system, is formed in a tertiary manner, and is in the mineral class of oxide, the Quartz group. The silky sheen and beautiful shimmers seen in this stone are created during its formation process.
With Quartz as its base, Crodicolite (asbestos) is trapped within the crystal. The fibers are generally twisted or crumpled which accounts for the various patterns. The amount of oxidation that occurs during its formation determines the coloring. In the gold shades, some oxidation has occurred and the golden coloring of the oxidized Crodicolite prevails. You may also be able to notice Hematite layers found much easier in the Golden color.
