Colored Diamond Production

Couples looking for diamond rings often ask why colored diamonds are so expensive and what makes them unique from other diamonds. Simply put, the amount of colored diamonds that are found on the Earth’s crust is relatively a lot less when compared to other diamonds. So the rarity of such gemstones, along with their unique color tones, make them a lot more valuable and expensive than colorless diamonds.

Colored diamonds are usually formed when nitrogen, boron, hydrogen, or other impurities gets trapped within the crystal lattice of a diamond during the crystallization process of the stone. However, diamond miners and manufacturers claim that only one in 10,000 naturally mined diamonds are colored. In that, red diamonds are the rarest ones, which is why they come at a much higher price tag.

Another interesting thing customers might not know is that there are only a few colored mines in the world. In fact, the number of currently active colored diamond mines across the world is estimated to be around just 50.
