A museum-grade specimen of outstanding beauty, quality, color, and size of the crystals (some over 7 cm) originated near the village of Sakoany, on the western banks of the Betsiboka River along Madagascar's northwestern coast.
Celestine, or Celestite, is a mineral composed of strontium sulfate (SrSO4). The mineral derives its name from its occasional delicate blue color. Celestine, along with the carbonate mineral strontianite, serves as a principal source of the element strontium, commonly utilized in fireworks and various metal alloys.
Celestine crystals from Madagascar are renowned for their intricate formations, including large, well-defined crystals, crystal clusters, and twinned crystals.
Highly coveted among collectors and enthusiasts, celestine is frequently incorporated into jewelry and decorative objects. Its blue hue renders it particularly desirable for use in jewelry, often serving as a substitute for blue topaz or blue sapphire.
