Caribbean Calcite aka Aragonite Tower

Aragonite is a carbonate mineral, one of the three most common naturally occurring crystal forms of calcium carbonate, CaCO3 (the other forms being the minerals calcite and vaterite). It is formed by biological and physical processes, including precipitation from marine and freshwater environments.

Blue Aragonite also known as Blue Caribbean, Blue Sky, or Caribbean Calcite. It is a very new combination mineral that was recently found in 2019 in Pakistan.
