Scolecite

Scolecite is a mineral belonging to the zeolite group, known for its channel-like crystalline structure that allows the absorption and exchange of ions.

🔬 Scolecite Identity Card

  • Chemical formula : CaAl₂Si₃O₁₀·3H₂O

  • Crystal system : Monoclinic (sometimes triclinic depending on the specimen)

  • Hardness : 5 to 5.5 on the Mohs scale

  • Density : Approximately 2.2 to 2.4

  • Luster : Vitreous to silky

  • Color : Colorless, white, sometimes pinkish or yellowish

  • Transparency : Transparent to translucent

🧬 Training and deposits

Scolecite typically forms in cavities of volcanic rocks , such as basalts, where fluids rich in silica and calcium allow crystallization. It is often associated with other zeolites such as stilbite or heulandite.

Known deposits :

  • India (Maharashtra, famous for its well-formed crystals)

  • Iceland

  • United States (Oregon, California)

  • Italy

  • France (Massif Central)

💎 Visual characteristics

Scolecite often occurs as fine needles , fans , or radiating aggregates . The crystals may resemble fibrous tufts, giving a very aesthetic and distinctive appearance. Its fracture is uneven and it may show perfect cleavage in one direction.

🌱 Esoteric properties (lithotherapy)

  • Inner peace and meditation

  • Restorative sleep

  • Spiritual opening

  • It is said to be a " stone of light" which helps to connect to higher planes and develop intuition.

🧼 Maintenance

As it is relatively fragile:

  • Avoid shocks

  • Do not expose it to acids or chemicals

  • Clean with clear water (no salt) and dry gently
