A celestite cluster is a group of naturally occurring celestite crystals, often found in geode formations. Celestite, also known as celestine, is a mineral consisting of strontium sulfate (SrSO₄) and is known for its delicate blue color. Celestite occurs mainly in sedimentary rocks, particularly dolomites, dolomitic limestones, and marls, either as a direct precipitate from aqueous solutions or, more usually, by the interaction of gypsum or anhydrite with Sr-rich waters.
These clusters are prized for their beauty and are often used in decorative displays and metaphysical practices.
It's color is typically sky blue color but can also be colorless, white, yellow, green, brown, or reddish with a vitreous to pearly luster.
It has an Orthorhombic crystal system with a hardness of 3-3.5 on the Mohs scale.
The main source of Celestite is from deposits on the northwestern coast of Madagascar, though it can be found in much smaller quantities worldwide.
