New in the shop! Celestite specimens from the Sakoany deposit, Boeny, Madagascar. For these, I wanted to focus on clarity, complete crystals, and a balance of quality and immediately attainable prices. I also didn’t want “just Celestite”… I wanted pieces that were memorable and eye catching. All of these are under $300 and immediately release is in person at The Crystalary. They will be released on the website in the next few days.
Celestite (SrSO₄) is a strontium sulfate mineral belonging to the barite group. Crystallizing in the orthorhombic system, it commonly forms tabular, prismatic, or bladed crystals, often occurring in radiating aggregates or crystal-lined cavities. Celestite forms primarily in sedimentary environments, particularly within limestone, dolostone, and evaporite deposits, where strontium-bearing fluids precipitate sulfate minerals. With a Mohs hardness of 3–3.5 and a relatively high specific gravity of approximately 3.9–4.0, celestite is both comparatively soft and unusually dense for a nonmetallic mineral.
Celestite is the principal ore of strontium and forms a solid-solution series with barite, in which strontium and barium substitute for one another. Its name derives from the Latin caelestis, meaning “heavenly,” in reference to its characteristic pale-blue crystals.
I will work on releasing these online tomorrow and if you’re local to Cincinnati you can find these in our gallery!
