What are genuine diamonds?

Genuine (natural) diamonds are formed deep within the earth's mantle, erupted to the surface through volcanic pipes and mined or gathered.

Genuine (man-made) diamonds are formed in laboratories that attempt to mimic the conditions deep within the earth -- extreme high pressure and ultra high temperature -- and are manufactured over time.

About 80% of all diamonds mined are industrial diamonds. Raw gem-quality diamonds are cut and polished into jewels.

All diamonds are formed from carbon.
