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.
