About celestine
Celestine (also known as celestite) is a strontium sulfate mineral that often forms tabular or prismatic crystals, noted for their delicate sky-blue to colorless hues. With Mohs hardness around 3–3.5 and perfect cleavage, it is soft and fragile, making it more suitable for mineral specimens than for everyday jewelry.
