Peach Calcite Heart, Pakistan

Calcite crystals are a form of calcium carbonate (CaCO₃) known for their diverse shapes, transparency, and vibrant range of colors. 

A notable characteristic of calcite is its reaction with weak acids like vinegar, which causes it to effervesce, or fizz, as it releases carbon dioxide. This property makes calcite crystals a key tool in geological identification and studies.

Each heart is unique- the carving you receive may differ in size, shape, coloring, and pattern than the one seen in the picture.
