Physical properties
Opaque cream-white, polished, with a pointed, faceted end; quartz has Mohs hardness 7, vitreous luster, and a trigonal crystal structure. The image does not show diagnostic features clearly enough to confirm quartz.
Formation & geological history
If quartz, it formed as silica crystallized from cooling fluids or magma in veins and cavities; quartz occurs in rocks of many geological ages.
Uses & applications
Small polished points are sold for collecting, décor, and sometimes jewelry or craft use.
Geological facts
Quartz is one of Earth’s most abundant minerals and has no cleavage, breaking instead with a curved, conchoidal fracture.
Field identification & locations
Check hardness and streak, and look for glassy luster and conchoidal fracture; cream-colored calcite or other minerals could resemble this specimen. Quartz is widespread worldwide.
