Etymology

Overite is named after Edwin J. Over, in recognition of his contributions to mineralogy. The mineral was granted IMA grandfathered status, indicating it was officially recognized before the establishment of the current IMA nomenclature system.

How to recognize it

Overite can be identified by its orthorhombic crystal system and its characteristic white to pale yellow color. It has a vitreous luster and a moderate density. The mineral is relatively soft, with a hardness that can be tested using the Mohs scale. A streak test may reveal a white streak. Due to its rarity and specific chemical composition, overite is often confused with other phosphate minerals, but its distinct chemical formula and crystal system aid in differentiation.

Trivia

Overite is notable for its unique chemical composition, which includes a tetrahydrate structure, making it relatively rare among phosphate minerals. It is also one of the few minerals named after a person directly involved in mineralogy. Its classification in both the Strunz and Dana systems highlights its distinct position within the phosphate mineral group.

Overite is not commonly traded as a gemstone or jewelry material, and its market is limited. As a mineral specimen, it may command prices between EUR 50 and EUR 200 depending on origin, clarity, and aesthetic appeal. Prices vary by source and are influenced by rarity and presentation.
