diamond
chemical formula: C (carbon)
color(s): colorless to pale yellow/brown; also blue, green, pink, red, orange, purple, gray, black (due to impurities/inclusions)
mineral group: native element (carbon)
Streak: typically none / colorless to white (diamond is harder than streak plate so streak is not diagnostic)
hardness: 10 (Mohs scale)
luster: adamantine (brilliant)
specific gravity: ~3.50–3.53
cleavage: perfect octahedral (cleaves in four directions)
transparency: transparent to translucent; can be opaque when heavily included
fracture: conchoidal to uneven; brittle
sources: primary: kimberlite and lamproite pipes; secondary: alluvial deposits. Major producing regions: Botswana, South Africa, Russia (Sakha/Yakutia), Canada (Northwest Territories), Australia (historically Argyle), Brazil, Democratic Republic of Congo, India (alluvial)
Important uses 1) Gemstones and jewelry (gem-quality diamonds) 2) Industrial abrasives and cutting/drilling tools (grinding wheels, saws, drill bits, diamond paste) 3) High-pressure research and tooling (diamond anvil cells, precision cutting/polishing) 4) Advanced technological uses (heat sinks/thermal conductors, optics, and emerging quantum/semiconductor applications using nitrogen-vacancy centers)
