High-quality Aragonite, particularly in its unique Sputnik formation, is a striking and fascinating mineral specimen. Aragonite itself is a carbonate mineral composed of calcium ca rbonate (CaCO₃) and is polymorphic with calcite, meaning that both have the same chemical composition but differ in crystal structure. While Aragonite typically forms in needle-like or tabular crystals, the Sputnik formations are an extraordinary example of a specific growth pattern.High-quality Aragonite can range in color from translucent to opaque, with shades varying from white, cream, yellow, orange, to even shades of brown or light blue.
