Shattuckite 8mm Round - 15-16 Inch R1796 milky to pink silicon dioxideShattuckite is a rare copper silicate hydroxide mineral. It occurs in bright turquoise blues and darker blues as well as rust reds, commonly with inclusions of copper in speckled patterns throughout the stone. Shattuckite is a pseudomorph, meaning it forms by replacing another minerals crystal structure atom by atom with its own crystal structure, with little alteration of the external shape of the original crystal.
