Druzy Fossil Shell
✦ The Crystal Clam ✦
Crystal lore: 🦋 Transformation🌳 Grounding🔮 Intuition
Also known as: Crystal fossil shell, Fossil clam, Crystallized clam
📜 Key facts
| Age | Pliocene to Pleistocene, roughly 3 million to tens of thousands of years old (Florida); varies elsewhere |
|---|---|
| Origin & sources | Florida, USA (the Fort Drum / Rucks Pit area, famous for crystal-lined fossil clams), plus material sold from Indonesia and elsewhere. |
| Composition | Fossil bivalve shells (clams such as Mercenaria) whose hollow insides are lined with sparkling druzy calcite or quartz. Some are partly replaced by silica |
How it forms
After a clam died, its two shells stayed closed and the inside stayed hollow. Mineral-rich groundwater seeped in and grew a lining of tiny crystals over thousands of years. Florida specimens are mostly calcite (they fizz in acid), and silica-replaced ones are quartz.
