Milky quartz with possible mica or feldspar inclusions
Quartz (SiO₂), likely with minor inclusions
AI-generated identification · may be incorrectWhite 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
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.
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.
