Physical properties

Hardness: 7 (Quartz) to 10 (Diamond). Color: Colorless. Luster: Adamantine to Vitreous. Cut: Faceted. Specific Gravity: 2.65 to 3.52.

Formation & geological history

Diamonds form under extreme pressure and heat deep in Earth's mantle over billions of years. Quartz forms from cooling magma or hydrothermal veins. This specimen appears man-made or professionally faceted from raw material.

Uses & applications

Primary use as jewelry (gemstone) or as decorative 'rhinestones' for clothing and accessories. Large diamonds are used for industrial cutting and drilling.

Geological facts

Diamond is the hardest natural substance known on Earth. Clear quartz was often used by ancient cultures for crystal balls and amulets.

Field identification & locations

Field identification of faceted stones is difficult; professional tools like a refractometer or thermal conductivity probe are required to distinguish between diamond, white sapphire, quartz, or cubic zirconia.
