Natural diamonds have captivated humanity for centuries with their beauty, rarity, and enduring value. But beyond their brilliance and cultural significance, there’s so much more to these extraordinary gemstones. Here are 8 fascinating facts about natural diamonds that might surprise you.
1. Natural Diamonds Are Billions of Years Old
Most natural diamonds were formed over a billion years ago, deep beneath the Earth’s surface. These gems are older than most life forms on Earth, making them one of the oldest substances you can own. Their formation occurs under intense heat and pressure, approximately 87 to 118 miles below the Earth’s crust, which is why they are so rare and unique.
2. They’re Made of a Single Element
Did you know that diamonds are made entirely of carbon? When carbon atoms are subjected to extreme heat and pressure, they bond together in a crystal structure, creating the hardest natural material on Earth. This pure carbon composition is what gives diamonds their incredible durability and brilliance. Any slight variation or change in temperature or pressure will cause the diamond to turn into graphite.
3. The First Diamonds Were Discovered in India
India was the first country to discover and mine diamonds, as early as the 4th century BCE. For centuries, India was the sole source of diamonds, with gems being found along the banks of the Krishna, Penner, and Godavari rivers. These Indian diamonds were treasured by royalty and became an integral part of cultural and religious traditions.
4. They’re Delivered to the Surface by Volcanoes
Natural diamonds are formed deep within the Earth, but how do they reach us? The answer lies in ancient volcanic eruptions. These eruptions carried diamonds to the Earth’s surface through kimberlite pipes, named after the South African town of Kimberley, where many diamond deposits were found.
5. Natural Diamonds Are Exceptionally Rare
Only about 30% of the diamonds mined worldwide are of gem quality, meaning they meet the standards required for fine jewellery. The rest are industrial-grade and used for cutting, grinding, and drilling. This scarcity of high-quality natural diamonds is one of the reasons they are so valuable.
6. They’re the Hardest Natural Material on Earth
Natural diamonds are renowned for their hardness, rating a perfect 10 on the Mohs scale of mineral hardness. This makes them incredibly resistant to scratches and damage, which is why they’re ideal for engagement rings and everyday jewellery.
7. A Diamond’s Sparkle Depends on Its Cut
The sparkle, or brilliance, of a diamond doesn’t come naturally—it’s determined by how well the diamond is cut. A well-cut diamond reflects light beautifully, creating the dazzling effect that diamonds are known for. The precision of the cut is what separates an average diamond from an extraordinary one.
8. Natural Diamonds Hold Their Value Over Time
Unlike many other luxury items, natural diamonds are known to retain and even appreciate in value over time. They’re considered a good asset to have due to their rarity and the growing global demand. Historical trends have shown that natural diamonds hold steady in economic uncertainty, making them a reliable and meaningful asset.
