Celestite | Madagascar

You will receive the piece pictured.

Celestite (mineralogically known as celestine) gets its name from the Latin caelestis, meaning "heavenly" or "celestial," in homage to its signature sky-blue color.

Formed as a strontium sulfate mineral, the world’s premier specimens originate from the famous Sakoany deposit on the northwestern coast of Madagascar. These pieces typically feature well-defined, glassy prismatic crystals clustered inside natural sedimentary geodes.

It gets its sky-blue colour from colour centers created by natural radiation. Trace amounts of radioactive elements in surrounding rocks expose the crystal to low-level background radiation over millions of years. This radiation knocks electrons out of their normal positions in the crystal lattice, trapping them in structural defects or impurities and causing the crystal to absorb specific wavelengths of light.

Come with a small stand, as pictured.

All the specimens we offer come with a lifetime authenticity guarantee.
