- Diamond is April’s birthstone.
- Diamonds are the hardest natural substance on Earth.
- Diamonds were formed billions of years ago through a combination of tremendous pressure and temperatures of 2000º –3000º F at depths between 75 and 120 miles beneath the earth’s surface.
- Diamond crystals are brought closer to the earth’s surface through volcanic activity.
- Diamonds can be found in shallow alluvial deposits where the crystals settle after being transported by rivers away from the kimberlite pipes by geologic activity.
- Fewer than 20 percent of the diamonds mined worldwide are true gem-quality.
- The earliest written account of diamonds dates back to around 500 B.C.
- Diamonds are virtually fireproof. To burn a diamond, it must be heated to 1292 degrees Fahrenheit. (The typical house fire reaches a temperature of approximately 1100 degrees).
