Milky Quartz with Chlorite/Moss Infusions

Physical Properties

Hardness: 7 on Mohs scale; Color: White to milky with green inclusions/staining; Luster: Vitreous to greasy; Crystal Structure: Hexagonal/Trigonal; Cleavage: None (conchoidal fracture); Specific Gravity: 2.65

Formation & Geological History

Formed through hydrothermal processes in veins where silica-rich fluids cooled and crystallized. The green coloration is likely due to chlorite inclusions or superficial moss/algae growth over geological time or recent exposure.

Uses & Applications

Quartz is used in glassmaking, electronics (as piezoelectric crystals), and as a landscaping or decorative stone. Low-grade specimens like this are primarily for landscaping or amateur collecting.

Geological Facts

Quartz is the second most abundant mineral in Earth's continental crust. Specimens featuring green inclusions like chlorite are often referred to as 'Phantom Quartz' if the green defines a previous growth stage of the crystal.

Field Identification & Locations

To identify in the field, check for the ability to scratch glass and lack of cleavage. Look for the characteristic conchoidal fracture. This specimen is commonly found in mountain ranges, stream beds, and areas with metamorphic or igneous activity.
