The Details on J Color Diamonds

We’ve now entered the final rung on the ‘near colorless’ ladder. At this stage, there’s no denying that we can see a subtle pop of color, especially when a J color is compared to a stone a few grades higher, like a D color stone.

A J color diamond with the right bells and whistles can still look absolutely stunning, especially if you are not too worried about a very, very subtle undertone of color in your stone. Even in white gold it can look fantastic if you like a warmer tone.

In fact, you could even throw away the rule book that says you should stick to higher colors for fancier cuts too! For example, if you’ve read my full color series above you’ll remember that I suggested sticking to the colorless range of stones if you are planning to go for a step cut like an emerald or an asscher. However, if you do like a warmer tone in your stone, there is absolutely nothing stopping you from going for a lower color grade.

I really like the warmth in this stone, and for a fraction of the price of a colorless stone (or even a high grade ‘near colorless’ like G or H) you might just be on to a winner.
