Physical properties
Colorless, transparent, vitreous luster. If quartz, Mohs hardness 7. If CZ, Mohs hardness 8-8.5. If glass, Mohs hardness 5.5. The image shows a heavily faceted, brilliant-cut clear material.
Formation & geological history
Quartz forms in igneous, metamorphic, and sedimentary environments. CZ and glass are manufactured synthetically.
Uses & applications
Used in jewelry, decorative items, and as a diamond simulant.
Geological facts
Clear quartz is the most common variety of quartz. CZ was synthesized for laser technology before becoming a popular gemstone simulant.
Field identification & locations
Can be identified by its brilliance and facet wear. Quartz will scratch glass, CZ will scratch quartz. Often found faceted for jewelry.
