How Cut Quality Impacts The Diamond’s Cost Per Carat Value

Higher cut quality removes more rough material and results in higher prices.

Although the carat weight of a diamond has the strongest effect on prices, the cut can still drastically increase or decrease its value. With a higher cut quality, you would expect the diamond’s cost per carat to increase.

This is because there is a higher wastage of the rough stone as more material needs to be removed in order to achieve better proportions and symmetry. On top of that, there are additional costs for skilled labor since polishing an ideal cut diamond requires significantly more time.

Ultimately, economics and profitability are the main driving forces behind every cutting decision. In the real world, it is not feasible for cutters to turn every single piece of rough into an ideal cut diamond since it will not be profitable to do so. This is the reason why the market is flooded with sub-par diamonds that are cut for weight retention and not for beauty.

And if you are wondering who on earth would buy stones with lower cut grades? The answer is definitely not me (and hopefully not you as well) – I want my diamonds to sparkle and be full of life. However, there are people in the market (both knowingly and unknowingly) who would still purchase poorly cut diamonds to fulfill their own budgets and needs.

My take on this is; if a diamond is cut well, then it will be visibly larger and more attractive than another one that is cut badly. Size does matter but it isn’t everything. Sometimes a stone with a smaller carat weight can be a much better purchase than a larger one because of its visual appeal and costs.

As you can probably tell by now, I always highlight and preach the importance of cut to all my readers. It is my personal belief most people will want a diamond that’s lively and not dull looking. Ultimately, whatever buying decisions you make still boils down to your own preference and balancing of the 4Cs.

A proper analysis of a diamond’s cut goes beyond the information found in a grading report and I hope you had learnt something useful on the website so far. Take a deep breath, go for a 10 minutes break, grab a cup of coffee and then, return here to familiarize yourself with the rest of the 4 Cs.

Once you are ready, I am going to give you more insider’s tips and show you a step by step guide to choosing the best diamond within your budget.

    Cathedral settings can be classified as a subset of solitaire designs. The main differences lie in the arches of a cathedral shank while a solitaire design can refer to any type of ring design where there is only a single gemstone used in the entire piece of jewelry.
