Oval Diamond Colour Guide
Evaluating colour in oval diamonds is quite subjective. As a general rule, smaller oval diamonds hide colour better than larger ones do.
That’s why, depending on the size of the diamond you are going to purchase, you may not need to buy a high-end colourless (D-E-F grade) stone, even if you want it to look colourless.
The chart below will help you to decide on the colour of the oval diamond to purchase.
|< .50 ct.||D - G||H - I||J - K||L - M||> M|
|.51-1.0 ct.||D - F||G||H - I||J - K||> K|
|1.0-2.0 ct.||D - F||D - F||G - H||I - J||> J|
|> 2.0 ct.||D - F||D - F||G||H - I||> I|
