⛰️Geological Context
Major rock‑forming minerals in igneous and metamorphic rocks; gem varieties occur in pegmatites and feldspar‑rich lavas.
🧪Scientific Properties
| Refractive Index | ≈1.52–1.58 (varies by species) |
|---|---|
| Specific Gravity | ≈2.55–2.75 |
| Luster | Vitreous; can show adularescence/aventurescence/labradorescence |
| Cleavage | Two directions at ~90° (perfect to good) |
| Optical Properties | Biaxial; features like exsolution lamellae produce optical effects |
🤝Ethical Sourcing
Optical effect stones (moonstone, sunstone, labradorite) are widely traded—seek disclosure of stabilization or dye; prefer transparent supply chains.
🧤Safety & Handling
- Moderate hardness (≈6–6.5)—avoid hard knocks.
- Cleavage can cause splitting—protect from impacts.
- Clean with mild soap and water
- avoid ultrasonic/steam.
🔎Similar Crystals
- Quartz (no cleavage, higher durability)
- Andesine (red/green treated feldspar)
- Glass imitations (no lamellar structure)
