Mineral Type and Geological Information
Hematite is an iron oxide mineral with the chemical formula Fe2O3. It is one of the most important iron-bearing minerals and has been collected, studied, and used throughout history due to its distinctive appearance and high iron content. Hematite belongs to the trigonal crystal system and can occur in several different habits, including massive, botryoidal, platy, earthy, and crystalline forms.
The term “Kidney Ore” is commonly used for rounded, botryoidal forms of hematite. These formations often have a smooth, bulbous, kidney-like surface, created as mineral material develops in rounded layers over time. This specimen displays the natural character associated with hematite kidney ore, making it an attractive example for mineral collectors and display.
Colour, Lustre and Natural Appearance
Hematite can vary in appearance from steel grey and metallic silver through to reddish brown, dark brown, black, and iron-red tones. Kidney ore specimens are often appreciated for their rounded form, dense feel, and natural iron-rich surface. Depending on lighting, the surface may show subtle metallic reflections, darker iron tones, or earthy red-brown areas.
Hematite is typically opaque and is well known for its reddish streak, even when the outer surface appears dark grey or black. This contrast is one of the classic identifying features of the mineral and is often used in geology and mineral study.
USA Locality and Collecting Interest
This specimen is from the USA, a country with a rich and varied geological history. Hematite deposits occur in many iron-bearing environments, including sedimentary iron formations, hydrothermal settings, and weathered iron-rich rocks. Kidney ore hematite is particularly valued by collectors because its natural rounded form creates a striking sculptural appearance without needing polishing or carving.
As a display piece, this hematite specimen works well in a mineral cabinet, natural history collection, study set, geology teaching selection, or as a gift for someone interested in crystals, rocks, fossils, minerals, earth science, or American geology.
