Red Is the Color of Love and Also of the Rarest Diamonds
The Allure of Red Diamonds
In short: Red diamonds are the rarest of all natural diamond colours — fewer than 30 certified gem-quality red diamonds exist worldwide, with most under 0.50ct. Top stones sell at auction for £750,000-£1,500,000+ per carat, making them roughly 200 times rarer than blue or pink diamonds. The colour comes from a unique lattice distortion rather than impurities. Lab-grown red diamonds offer the same hue for a tiny fraction.
Red diamonds are among the most fascinating and sought-after gemstones in the world. Their rarity and vibrant hue set them apart in the world of colored diamonds, making them a symbol of love, passion, and mystery. The red diamond’s fiery appearance and its rarity create an aura of exclusivity and prestige that few other gemstones can match.
The Science Behind the Color
the red color in these diamonds is the result of a unique structural anomaly within the diamond crystal. Unlike other colored diamonds, where the color is due to impurities or inclusions, red diamonds owe their color to a rare distortion in the crystal lattice that changes how light passes through the stone. This phenomenon, known as "plastic deformation," alters the absorption of light, giving the diamond its distinctive red hue. It’s this combination of natural rarity and complex formation process that makes red diamonds so incredibly valuable.
