facts about diamonds:
- Older than dinosaurs
Most natural diamonds are over a billion years old, and some are more than 3 billion. You’re literally wearing a piece of Earth that formed long before dinosaurs existed. - Made of something very ordinary
Diamonds are made of just carbon, the same element as in pencil “lead.” The only difference is how the atoms are arranged, which turns something common into the hardest natural material we know. - Hardest natural material
On the Mohs scale, diamonds are a 10. Only another diamond can scratch a diamond, which is why they’re perfect for engagement rings and are also used in drills and cutting tools. - Most diamonds never become jewelry
Only a small share of diamonds mined are clean and beautiful enough for jewelry. Most are used in industry for cutting, grinding, and drilling. - Not always colorless
Diamonds can be yellow, brown, pink, blue, green, red, and black. Some of the rarest and most expensive diamonds in the world are actually colored, not colorless.
