Diamonds have long been symbols of beauty, strength, and luxury. But beyond their sparkling appearance lies a world of surprising facts. Here are Top 8 Fascinating Facts About Diamonds for Jewelry Lovers will unveil secrets you never expected. Get ready to fall in love with diamonds all over again.
Fact 1: Only a diamond can cut another diamond
In Greek culture, the word “diamond” originates from “adamas,” meaning indestructible. On the Mohs scale of hardness, diamonds score a perfect 10 out of 10 (while sapphire and ruby score 9), making this transparent crystal unmatched in hardness. Remarkably, only another diamond can scratch a diamond

Fact 2: Diamonds don’t shine
Many people think diamonds emit their own light or “shine” like in Rihanna’s famous lyric, “Shine bright like a diamond.” But in reality, diamonds reflect light — they don’t produce it. Here’s the scientific explanation: When light hits a diamond, part of it reflects off the surface — this is called external reflection. Another portion of the light enters the diamond and bends due to its high optical density — this is refraction. The light then bounces around inside the diamond and reflects off the internal surfaces — known as internal reflection. These combined effects are what give diamonds their brilliant sparkle
In reality, this crystal reflects light rather than emitting it.
Fact 3.Diamonds are the tears of the gods
In ancient Greek and Roman culture, diamonds were believed to be the tears of the gods or fragments fallen from the stars.
Fact 4. The first diamond engagement ring appeared in the 15th century
In 1477, Archduke Maximilian I of Austria proposed to Mary of Burgundy, a French noblewoman, with a gold ring set with diamonds. Notably, the ring featured the letter “M” — symbolizing Mary’s name — filled with tiny diamond. Check out diamond ring care tips here.
Fact 5. Need 250 tons of earth for just one carat of diamond
One reason diamonds are considered so rare is that approximately 250 tons of earth must be mined to produce just a single carat of diamond.
Fact 6. Diamonds are formed over 100 km deep underground
These sparkling crystals are formed in complete darkness, deep within the Earth. Typically, diamonds are found at depths ranging from 140 to 190 kilometers below the surface. In some cases, volcanic eruptions can carry diamonds up to the surface through powerful geological forces.
To obtain just one carat of diamond, workers have to move approximately 250 tons of earth.
Fact 7. Made of 100% carbon
Interestingly, the only element that forms this transparent crystal is carbon. A diamond is composed entirely of pure carbon atoms arranged in a unique, tightly bonded crystal structure.
Fact 8. Diamonds are 1 to 3 billion years old
Most diamonds are between 1 and 3.3 billion years old, with some rare ones reaching up to 4 billion years. Isn’t that truly astonishing?
