Halite
About
Halite, commonly known as rock salt, is a mineral composed of sodium chloride (NaCl). Found in a variety of colours including white, pink, blue, and clear, halite often forms cubic crystals and is highly soluble in water. Known for its cleansing and purifying properties, halite is both a geological wonder and a staple in everyday life. Major sources include the United States, Poland, and Germany.
Birthstones & Anniversaries
Halite is not a traditional birthstone but is associated with purification, clarity, and the zodiac sign Pisces, symbolising emotional balance and cleansing.
Crystal Healing Energy
The overarching theme of halite is purification and renewal. It is thought to cleanse negative energy, enhance clarity, and create a sense of calm. Halite is often used in spiritual practices to detoxify the mind and body, promote emotional balance, and support transformative growth.
Facts
Solubility: Halite dissolves easily in water, making it sensitive to moisture and unsuitable for prolonged exposure to humidity.
Geological Formation: Halite forms through the evaporation of saline water in arid climates, often found in salt beds and salt domes.
Rare Colours: Blue and pink halite, often found in salt mines, are rare and prized for their unique hues.
Major Sources: The largest deposits of halite are found in Poland (Wieliczka Salt Mine), the United States, and Germany.
