15 Interesting Facts about Diamonds You Probably Didn’t Know

Diamonds, those shiny symbols of love, and all that jazz, are some of the most incredible rocks on Earth. You might think you know the whole deal about these sparklers, but get ready for some seriously interesting facts about diamonds.

Fact Check: Trivia Questions About Diamonds

1. Origin of the term ‘diamond’: The term ‘diamond’ comes from the Greek word Adamas, meaning non-breakable, durable, and scratch-resistant. Ancient Romans and Greeks believed diamonds were formed by Gods' tears and Cupid's arrowheads and symbolized protection.

2. Diamond is made of a single element: You read that right. An easily available element, carbon, the main ingredient of a diamond, is formed when a singular carbon atom merges with up to four other atoms to create a three-dimensional crystalline composition through its built-up chemical bonds.

3. The importance of heat and pressure: Heat is essential for bonding carbon atoms and bringing diamonds to the surface- precisely, a whopping 725,000 pounds per square inch of pressure at a blazing temperature of approximately 2200°F. Additionally, diamonds are pushed up to the surface through volcanic eruptions.

5. India-the first diamond hub: Being the first country to have discovered diamonds, ancient Indian culture encourages embedding these rare stones in the statues of their gods and deities. With time, as Indian reserves started depleting, other mines were developed globally.

6. Getting engaged with a diamond ring - a royal tradition: A status symbol of the elite, the tradition of gifting diamond engagement rings goes back to the year 1477 when Archduke Maximillian of Austria proposed to Mary of Burgundy.

7. The after-effects of the cutting and polishing process: This process ensures the rough diamond reaches its full potential, during which the diamond loses up to 50% of its original rough carat weight.

8. Not all diamonds are colorless: Various natural diamonds are formed in color – yellow, red, pink, blue, brown, orange, etc. – and have unique characteristics and inclusions.

13. One in a million: In reality, around 1 million units of mined rock yield only one part diamond. Miners can roughly locate one pound of diamond for every one million pounds of the diamond-bearing host rock (a whopping 500,000 metric tonnes), leading to limited production.
