Diamond is one of the two best known forms (or allotropes) of carbon, whose hardness and high dispersion of light make it useful for industrial applications and jewelry. (The other equally well known allotrope is graphite.) 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 lustre. About 130 million carats (26,000 kg) are mined annually, with a total value of nearly dollar|USD $" target="_blank" >*9 billion. About 100,000 kg are synthesized annually.
