Physical properties
Hardness: 7 (Quartz) or 8.5 (CZ); Color: Colorless/Transparent; Luster: Vitreous to Adamantine; Crystal System: Trigonal (Quartz) or Isometric (CZ)
Formation & geological history
Quartz forms in igneous, metamorphic, and sedimentary environments through hydrothermal activity. Synthetic simulants are lab-grown.
Uses & applications
Used in jewelry as a gemstone, and in high precision electronics (Quartz) or as a decorative diamond alternative (CZ).
Geological facts
Clear quartz is also known as rock crystal. CZ was originally developed by Soviet scientists for laser technology before becoming a jewelry staple.
Field identification & locations
Check for inclusions to distinguish natural quartz from glass or lab-grown stones. Use a diamond tester to differentiate from real diamond.
