Pollucite is a cesium-rich member of the zeolite group and an important natural source of cesium. It commonly occurs in lithium- and cesium-rich granitic pegmatites, where it may be associated with Petalite, Lepidolite, Spodumene, Quartz, and other rare-element minerals.
Quick Facts
- Formula: (Cs,Na)₂(Al₂Si₄O₁₂) · 2H₂O
- Mineral group: Zeolite group
- Crystal system: Isometric
- Mohs hardness: About 6.5–7
- Typical colors: Usually colorless or white; sometimes pale gray, pink, blue, or violet
- Tenacity: Very brittle despite its hardness
History & Name
Pollucite was named for Pollux, the mythological twin of Castor. The pairing refers to its frequent association with Petalite, which was historically called castorite. This mineralogical naming pair reflects the way both minerals can occur together in rare-element pegmatites.
Metaphysical Meaning
Modern metaphysical traditions sometimes associate Pollucite with clarity, quiet potential, structure, concentration, and recognizing value that is not immediately obvious. These are symbolic traditions rather than scientifically verified properties.
Common Intentions
- Quiet concentration
- Recognizing hidden potential
- Building structure around a new idea
- Clear priorities
- Patient study and observation
Care & Handling
Pollucite is fairly hard but notably brittle. Protect crystals from knocks and drops, especially along thin edges. Clean gently with mild soap, lukewarm water, and a soft cloth or brush. Avoid harsh chemicals, steam, and aggressive ultrasonic cleaning on fractured specimens.
