White quartz bead strand
Quartz, silicon dioxide (SiO₂), likely milky or translucent quartz; beads are polished and drilled
AI-generated identification · may be incorrectMohs hardness 7; white to translucent, glassy luster, trigonal crystal structure, no cleavage, conchoidal fracture; specific gravity about 2.65. The image shows rounded, polished beads, so natural internal texture is difficult to assess.

Physical properties
Mohs hardness 7; white to translucent, glassy luster, trigonal crystal structure, no cleavage, conchoidal fracture; specific gravity about 2.65. The image shows rounded, polished beads, so natural internal texture is difficult to assess.
Formation & geological history
Quartz forms in igneous and hydrothermal environments and in many sedimentary and metamorphic rocks; it occurs throughout Earth’s crust and spans a wide range of geological ages.
Uses & applications
Used in jewelry, ornaments, glassmaking, electronics, and industrial abrasives; this strand is principally decorative.
Geological facts
Quartz is one of the most abundant minerals in Earth’s continental crust and commonly occurs as milky, clear, or colored varieties.
Field identification & locations
Quartz beads are hard and glassy, but appearance alone cannot confirm the material; glass or other stones can imitate them. Common sources include Brazil, Madagascar, and the United States.
