DX Quality

It is important to us that you choose a diamond that is both good value and that you absolutely love! With this in mind, we recommend the following gradings when considering the characteristics of your perfect diamond.


The Carat weight of the diamond really depends on your budget and should only be considered in conjunction with Cut, Colour & Clarity.


To maximise brilliance, we recommend a cut grading of Excellent or Super Ideal for round diamonds, and Very Good, Excellent or Super Ideal for fancy shapes (non-rounds).


For a beautiful white colour, we recommend a colour grading within the range of D (absolutely colourless) to G (near-colourless and excellent value).


To avoid inclusions visible to the naked eye and still maintain great value, we recommend a clarity grading of either SI1, VS2 or VS1.

"Esther answered all our questions with so much detail it made the purchasing experience very easy and gave us the confidence that we were getting an amazing quality diamond! We were very impressed by the range of high-grade diamonds they had available compared to other jewellers. They even had our custom order ready under lead time - highly recommended."
