Cloudy white to translucent snow-white caused by Tyndall scattering from millions of microscopic fluid cavities trapped during rapid crystal growth.
Common in hydrothermal quartz veins and pegmatite margins worldwide.
Often forms the snowy matrix pedestal for gem tourmaline, aquamarine, or gold specimens, and is cut into serene white cabochons.
Smooth cabochons, beads, and sculptural contemporary jewelry.
Untreated natural material.
Wash with warm soapy water; avoid thermal shock due to internal fluid inclusions.
Associated with calm, simplicity, and quiet reflection.
