2.8" Yellow-Orange Aragonite Formation - Peru

 
This is a beautiful formation of yellow-orange cave aragonite, collected from Peru. The aragonite formed along the walls of a cave, resulting in the appearance of being botryoidal. When viewing the mineral under short and long wave UV, this specimen fluoresces a faint, white-yellow color. Following UV exposure, the aragonite displays phosphorescent properties that remain for a short time.

Aragonite is a carbonate mineral with the chemical composition of CaCO3. It is a pseudomorph after calcite and varies in colors depending on impurities. It displays a translucent to white color when pure, and when impure can vary between yellow, green, pink, blue and brown. Typically forming in low temperature hydrothermal veins, It is also known to form in hot springs, as precipitates from chemicals in sedimentary rock, and in some cases as crystals in fossilized sea creatures.
