FAQs about D Colour Diamonds

At Blue Nile, you'll find colour grades that range from K (faintly colored) to D (colorless). Lower colour grades exist, but L–Z colour grade diamonds aren't available at Blue Nile.

Diamonds with a D colour grade are absolutely colourless and the rarest of all colour grades.

Colour, cut, clarity, and carat—the 4Cs—all affect a diamond's price. A D-colour diamond will cost much more than a K-colour diamond. When working within a budget, try prioritizing cut over colour to maximise brilliance.

The larger the diamond, the easier you'll notice the colour. For this reason, we recommend shopping for an H colour grade or higher if your diamond is one carat or larger.

D Colour .93 Carat Diamond Review

Excellent Ring and Service

This truly was the perfect setting for my future wife. The delicate twist and double row of French pave truly makes the stone POP. I got a .93 carat diamond with good cut clarity and colour and the setting makes it look bigger. Her family is convinced that it’s over a carat. The ring has real wow factor and I’m very pleased

D Colour 2.5 Carat Diamond Review


My boyfriend and I recently started looking for a diamond ring, and after we looked at a couple diamonds from jewellers he knew, we decided to look on the Blue Nile website. We were very impressed with the selection, and after 3 days of many phone calls to the customer service representatives at Blue Nile to ask for information and opinions on the diamonds that we were interested in, we finally decided on a 2.5 Carat, D colour, S1 2 diamond. The image of the diamond was perfect, 3D and spinning so we could see it from all angles. We had the diamond set in a Blue Nile setting, and it was delivered to my home about 2 weeks later. The ring is beautiful, the service is exceptional. We highly recommend this website and would definitely buy from Blue Nile again.
