Diamonds! Diamonds!! Diamonds!!!
Diamonds are women's best friend. Their hardness and brilliant dispersion of light make them useful for industrial applications and jewelry.
Diamonds are specifically renowned as a mineral with superlative physical qualities — they make excellent abrasives because they can be scratched only by other diamonds, Borazon, ultrahard fullerite, or aggregated diamond nanorods, which also means they hold a polish extremely well and retain luster.
About 130 million carats (26,000 kg) of diamonds are mined annually with a total value of nearly USD $9 billion.
About 100 tons are synthesized annually.
