What are the different types of diamond cuts?
Choosing a piece of Jewellery takes careful consideration, whether you’re looking to pop the question with your dream engagement ring, investing in a special piece for your own collection or buying a special gift. The cut is one of the most important considerations; it decides the whole personality of your piece and is one of the 4 C’s of diamond buying.
Diamond Cuts
Diamond Cut Quality
The diamond cut can refer both to the quality of diamond cut and to the shape of the diamond. The grade of the cut can be certified by GIA if it is a round diamond, and independently for other diamond shapes. The diamond cut impacts the amount of light that is reflected internally into the stone. An Excellent Cut creates the most sparkly diamonds. Meaning, if you value a glittering stone the most, then it’s best to opt for an excellent cut or very good cut. Choosing a low quality cut can cause the diamond to appear dull or glassy.
The grading of diamond cuts includes:
-
Excellent: The very best quality cut, well proportioned and symmetrical with brilliant sparkle.
-
Very good: A very good quality cut, just slightly less than Excellent, great proportions, brilliant sparkle and with it a smaller price tag.
-
Good: A great choice for balancing both brilliance and value.
-
Fair or Poor: Be wary of a fair or poor cut as the light can leak from the sides or bottom of the stone, reducing its overall shine.
Diamond Cut Shape
The Diamond cut can also refer to the shape of the diamond. The different shapes give your piece of jewellery its personality. Choose from a classic shape like a round cut or emerald, or opt for something a little bit different, like a marquise for a more modern look.
Round cut diamond

Also known as a round-brilliant cut, this cone shaped diamond is the most iconic style for engagement rings. With its cone shape and rounded-off top, typically, a round brilliant diamond has 58 facets – meaning it maximises light reflection and sparkle.
