Physical properties
Polished, translucent white spherical beads with a glassy-to-pearly sheen. If quartz: Mohs hardness 7, trigonal crystal system, no cleavage, specific gravity about 2.65; moonstone instead has hardness 6–6.5 and may show a floating blue-white sheen.
Formation & geological history
Quartz forms in veins and cavities from silica-rich fluids; moonstone is feldspar crystallized in igneous rocks. No age or locality can be determined from the image.
Uses & applications
Beads are used in jewelry and crafts; quartz is also used in glass, abrasives, and electronics.
Geological facts
The beads are drilled and polished, so surface appearance alone is not enough to distinguish quartz from feldspar, glass, or another material.
Field identification & locations
Check a discreet spot for hardness and inspect for moonstone’s shifting adularescence; a gemological test is needed for reliable identification. Similar materials occur worldwide.
