The Details About D Color Diamonds

Simply put, ‘D’ is the crème de la crème of diamond color grades.

D color diamonds have the least amount of color in them (technically colorless), and this makes them the brightest, whitest and iciest of all the colors on the scale. It also makes them the rarest of all the colors, and - yes, you’ve guessed it - the cruelest on your wallet.

Colorless diamonds (grades D-F) make up less than 1% of the world’s supply of diamonds, and as a result you are expected to pay a premium for the privilege of owning one.

However, a word of warning as you embark on that journey. Do not assume that buying the best color diamond means you will get the most beautiful icy white stone. The best color (and indeed clarity) in the world is wasted on a diamond that is not cut correctly. If you need some guidance on this, just remember this ancient proverb; every time someone buys a poorly cut diamond, an angel loses its wings.
