Small quartz crystal (likely milky quartz)

Quartz, silicon dioxide (SiO₂)

AI-generated identification · may be incorrect

Translucent white to colorless, vitreous luster, irregular fractured form; hardness 7 on Mohs scale, trigonal crystal structure, no cleavage, specific gravity about 2.65. The tiny size and image do not allow reliable confirmation; pale feldspar or another mineral is also possible.

Physical properties

Formation & geological history

Quartz crystallizes from silica-rich fluids or magma and is common in veins and igneous and metamorphic rocks. Quartz is geologically widespread across many ages.

Uses & applications

Quartz is used in glassmaking, electronics, abrasives, and jewelry; this grain is too small and included for significant commercial use.

Geological facts

Quartz is among Earth's most abundant minerals and resists weathering, helping it accumulate in sands and gravels.

Field identification & locations

Look for glassy luster, hardness sufficient to scratch glass, and lack of cleavage; confirm with a hand lens and hardness test on a larger sample. Found worldwide in veins, pegmatites, and river or beach deposits.
