Kutnohorite is a carbonate mineral in the dolomite group that forms rhombohedral to scalenohedral crystals with a vitreous to resinous luster. It commonly occurs as aggregates and crusts in skarn and carbonate rocks, displaying warm orange-brown to brown hues that can intensify in shaded pockets. Crystals may show subtle zoning and sometimes form in composite clusters that highlight their geometric faces. Notable specimens come from classic skarn localities where calcium and manganese-rich fluids have interacted with carbonate hosts, contributing to balanced color and clarity in dry, well-formed crystals.

About Kutnohorite
Collectors seek kutnohorite for its distinctive color and crystal habit, often paired with associated manganese-bearing minerals. The mineral’s relatively moderate hardness and clear crystallography can make it an appealing study for cabinet-sized specimens and thumbnail clusters alike. While not as ubiquitous as more common carbonates, high-quality kutnohorite from notable districts stands out for display value and mineralogical interest, especially when enhanced by sharp edges and clean luster.
