Torbernite is a radioactive mineral with the formula Cu(UO₂)₂(PO₄)₂·10-12H₂O, belonging to the uraninite group 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.

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 infused the specimen with an acrylic polymer resulting in a more rigid specimen that won’t break, or disintegrate under normal circumstances over time.
