The Heritage & Discovery
Named in honor of American mineralogist Lewis S. Ramsdell, Ramsdellite was first identified in 1943 from its type locality in the Lake Valley Mining District of New Mexico, USA. This distinctly American mineral is a dimorph of the more common pyrolusite, meaning it shares the same chemical composition but has a different crystal structure. As a manganese dioxide mineral, it is primarily sought after by collectors of rare species and locality-specific specimens. Due to its opacity, perfect cleavage, and metallic nature, Ramsdellite is almost never faceted, making a 5.70 carat specimen like FREAKINGCAT an exceptionally rare and significant example, likely presented as a fine cabochon or a well-formed crystal aggregate.
Mineralogical Profile
Ramsdellite is an opaque mineral characterized by its iron-black to steel-gray color and a bright, metallic luster. It crystallizes in the orthorhombic system and possesses perfect cleavage in two directions, rendering it quite fragile. As an opaque metallic mineral, its Refractive Index is not determined by standard gemological methods; instead, its high surface reflectivity is a key diagnostic feature. The Specific Gravity of Ramsdellite ranges from approximately 4.70 to 4.80. Geologically, it forms as a secondary mineral in the oxidized zones of manganese deposits, where it is often found in association with other manganese oxides like pyrolusite, cryptomelane, and hollandite.
Chemical Formula: Mn O2
