Physical properties
Salmon-pink to orange, vitreous to pearly luster, with blocky cleavage surfaces; Mohs hardness about 6 and specific gravity around 2.6. The pieces appear opaque and irregular, with no clear crystal faces.
Formation & geological history
Feldspar crystallizes as magma cools, commonly in granite and pegmatite; it may also occur in metamorphic rocks. Its age depends on the source rock and cannot be determined from the image.
Uses & applications
Feldspar is used in glass and ceramic manufacture; attractive, clean crystals may be collected or occasionally cut as gems.
Geological facts
Potassium feldspar is one of the most abundant minerals in Earth’s continental crust.
Field identification & locations
The warm color and blocky cleavage are consistent with feldspar, but the image alone cannot confirm the species; a hardness or mineral test would help distinguish it from calcite or other orange minerals. Common in granites and pegmatites worldwide.
