Celestite - Specimen

Locality: Sakoany area, Mahajanga Province, Madagascar

Celestine is strontium sulfate, SrSO₄. It is soft, at 3 to 3.5 on the Mohs scale, and heavy for a translucent mineral, with a density of about 4. It typically fills fissures and cavities in carbonate rocks, deposited by groundwater or basin brines carrying strontium.

This one of a kind Celestite mineral specimen from Madagascar features a rounded natural geode form filled with blue-grey to smoky blue Celestite crystals. The open cavity reveals glassy, sharply formed crystals with larger points and blocky growths surrounded by smaller sparkling crystals along the rim. The outer matrix is left natural, with pale grey, cream, and earthy beige tones that contrast beautifully against the cool blue crystal interior.

Celestite, also called Celestine, is a strontium sulfate mineral known for its soft blue colour, high specific gravity, and attractive crystal-lined geode formations. Its name comes from the Latin caelestis, meaning “heavenly” or “celestial,” a reference to the mineral’s delicate sky-blue colour. Madagascar is one of the best-known modern sources of Celestite geodes, especially the pale blue to blue-grey specimens collected from sedimentary deposits and commonly displayed as natural crystal cavities.

In crystal traditions, celestite is associated with peace, calm and gentle communication, and with the throat and third eye chakras.
