Every diamond is immensely old, formed long before dinosaurs roamed the earth. The youngest diamond is 900 million years old, and the oldest is 3.2 billion years old.

Every diamond is unique; no two are alike.

The very word 'diamond' comes from the Greek term adamas meaning unconquerable.

Diamonds exist in many colors, the rarest of all being red.

Diamonds were first mined in India more than 2800 years ago.

Each stone loses, on average, more than half its original weight during cutting and polishing.

The word 'carat' comes from the carob tree whose seed was used as the standard of weighing precious stones.

Less than 5% of all the diamonds made into jewelry are larger than one carat.
