Physical properties
Hardness: 3.5-4 (Mohs scale); Color: pale yellow, tan, or light brown; Luster: vitreous to dull; Crystal structure: monoclinic or tetragonal; Surface: crystalline, rough, or jagged.
Formation & geological history
Biogenic mineral formation occurring within the human urinary tract due to the precipitation of dissolved minerals from urine. Common age of formation ranges from days to several months.
Uses & applications
Biological mineral specimen; typically analyzed via infrared spectroscopy or X-ray diffraction in pathology labs to determine medical treatment.
Geological facts
Human-derived biomineralizations like kidney stones and gallstones consist of real mineral crystals (like whewellite and weddellite) produced by the human body through biomineralization processes.
Field identification & locations
Identified by its small size, crystalline texture, yellowish/brownish color, and typical passage from the urinary tract onto tissue or filter mesh.
