Physical properties

Formation & geological history

Quartz crystallizes from silica-rich igneous and hydrothermal fluids and occurs widely in veins, cavities, and metamorphic rocks. The pictured piece is human-shaped and polished, likely made from massive or milky quartz of no determinable age.

Uses & applications

Used for carvings, ornaments, lapidary objects, countertops, abrasives, glass, and electronics; this specimen is primarily decorative or tactile. It has modest jewelry and collecting value unless unusually clear or attractively patterned.

Geological facts

Milky appearance results from microscopic fluid inclusions, fractures, or dispersed impurities that scatter light. Quartz is one of Earth’s most abundant and chemically durable minerals.

Field identification & locations

Identify by its glassy appearance, translucency, lack of cleavage, and ability to scratch ordinary glass; it should not be confused with softer calcite or man-made glass. Common worldwide, especially in Brazil, Madagascar, the United States, and alpine veins.
