Milky quartz with possible mica or feldspar inclusions

Quartz (SiO₂), likely with minor inclusions

AI-generated identification · may be incorrect

White to translucent, vitreous-to-waxy luster, uneven fracture, and no obvious cleavage; quartz hardness is 7 Mohs and specific gravity about 2.65. The gray reflective patches may be mica, feldspar, or surface matrix, making exact identification uncertain from the image.

Physical properties

Formation & geological history

Likely formed in a hydrothermal vein or pegmatite as silica-rich fluids cooled in fractures; quartz deposits range from Precambrian to modern geological ages. It commonly occurs with feldspar, mica, and metal-bearing minerals.

Uses & applications

Used for glass, electronics, engineered stone, abrasives, and ornamental specimens; attractive translucent pieces may be cut or polished, though this specimen appears low-grade for jewelry.

Geological facts

Milky quartz is cloudy because microscopic fluid inclusions, fractures, or mineral impurities scatter light. It is one of the most abundant forms of quartz.

Field identification & locations

Identify by its glassy appearance, hardness, lack of cleavage, and inability to scratch it with a steel nail; a streak test is white. Common worldwide in veins, granites, and pegmatites.
