Approximate Weight: 122 Grams
Locality: Unknown lead mine, Guangxi Provence, China
Torbernite is a radioactive mineral with the formula Cu(UO₂)₂(PO₄)₂·10-12H₂O, typically occurring as bright green, tabular crystals or as fine-grained masses. Torbernite gets its vibrant color from both its high uranium and copper contents giving it a distinctive appearance and unique crystal structure.
Parsonsite is a rare lead uranium phosphate mineral (Pb₂(UO₂)(PO₄)₂·2H₂O) known for its striking color range from pale yellow to deep orange. Comprising about 45% lead and 25% uranium, Parsonsite forms in intriguing structures like elongated pseudo-monoclinic crystals, radial spherulites, encrustations, and powdery aggregates.
This specimen was stabilized with Paraloid B-72, a commonly used conservation material in the field of mineral preservation, providing excellent protective qualities for long-term conservation. The stabilization process infuses the specimen with an acrylic polymer resulting in a more rigid specimen that won’t break, or disintegrate under normal circumstances over time.
