Physical properties
Hardness 7 (Quartz) to 8.5 (Cubic Zirconia) on Mohs scale. Colorless, vitreous to adamantine luster, trigonal crystal system when natural, excellent clarity with brilliant light dispersion.
Formation & geological history
Natural clear quartz forms in pegmatites, hydrothermal veins, and metamorphic rocks. Synthetic diamond simulants like cubic zirconia are synthesized in high-temperature laboratory environments.
Uses & applications
Used widely in fashion jewelry, accessories, decorative chandelier prisms, and gemstone collections as an affordable diamond alternative.
Geological facts
Quartz is one of the most abundant minerals on Earth's surface. Faceted pear-shaped stones like this mimic the classic teardrop diamond cut.
Field identification & locations
Can be identified by testing thermal conductivity or specific gravity to distinguish between quartz, cubic zirconia, white sapphire, or natural diamond.
