1.45" Zoned, Blue Halite Crystal - Igdar, Turkey
This is a well formed, 1.45" tall crystal of blue halite collect near Igdar in Eastern Turkey. It displays excellent color saturation and zoning within the crystal.
About Blue Halite
Halite, more commonly known as rock salt, is a form of the mineral sodium chloride (NaCl). It forms when salt-rich waters evaporate and can be colored by mineral impurities. Blue halite is relatively rare and highly sought after by mineral collectors due to its vivid coloration and water-soluble fragility.
The blue color in halite (rock salt) is primarily due to the presence of tiny, colloidal-sized clusters of sodium metal, known as "colloidal sodium", within the crystal lattice. This phenomenon is often triggered by natural radiation, such as that from surrounding sylvite (potassium chloride), which can cause electrons to be knocked off chloride ions and trapped by sodium ions, eventually leading to the formation of these sodium clusters.
