K colour grade diamonds are the highest colour grade stones within the faint colour category. They offer a very slight yellow hue that makes them a great choice for yellow gold settings.
Colourless diamonds and near colourless diamonds are more expensive than faint colour diamonds. K colour grade diamonds offer a tone difference so slight you likely wouldn’t be able to tell the difference between a K-grade stone and a J-grade stone if you viewed them side by side. This makes a K-grade diamond a much better value for the price than a J-grade diamond.
With many cuts, yes. If you are purchasing a stone of one-carat weight or more, Blue Nile generally recommends an H colour grade or higher, but there are no hard-and-fast rules.
It is very rare to find a diamond that doesn't have any colour at all, which is why colourless diamonds are so expensive. The vast majority of diamonds have some level of naturally occurring colour.
