Engagement Ring Advice: What Is The Diamond ‘Cut’?

When purchasing a piece of diamond jewellery there are lots of crucial characteristics you need to consider. From the weight of the diamond to the colour of it, you want to make sure you are purchasing a diamond of a high quality. One aspect that is imperative is the diamond’s cut.

The term ‘diamond cut’ is something that leads to a lot of confusion. It is undoubtedly one of the most important qualities of any diamond. However, a lot of people get the cut confused with the shape. ‘Heart’, ‘square’, ‘oval’, ‘pear’ and alike all relate to the shape of the diamond. However, the cut is something else entirely.


What is the diamond cut? This is used to describe the reflective qualities of the diamond. If the diamond is cut to proportion it is going to have a desirable sparkling and twinkling quality. However, if the diamond is too shallow or too deep, the light will spill out. Thus, the reflective qualities of the diamond will not be as spectacular.

A diamond’s cut is something that is graded via the GIA certification system. When buying any piece of diamond jewellery it is imperative to seek this certification. It grades a diamond based on cut, colour, carat and clarity. Therefore, you will easily be able to determine whether the diamond you are considering is of quality.

So, how is a diamond’s cut graded? There are five different grades. These are as follows; Ideal, Premium, Very Good, Good, and Fair. Evidently, this is in order of the best cut to the worst cut. Ideal diamonds offer maximum brilliance. However, they are also very expensive as well. To find the perfect balance between a stunning diamond engagement ring and remaining within your budget you should opt for one with a grading of ‘Very Good’.

Now that you know what a diamond cut is, let’s delve deeper into a diamond’s shape. As mentioned earlier, this is where the confusion usually lies as people often refer to the shape of a diamond as its cut. There are many fantastic diamond shapes to choose from. There is no right or wrong, it is all about finding the right shape for your personality and taste. If you are buying an important piece of jewellery, such as a wedding ring, you may wish to consider other aspects – for instance, how the diamond suits your hand shape. After all, you are going to be wearing it for the rest of your life.

So, to end, let’s reveal some of the different shapes you can choose between…


  • Round
  • Princess
  • Emerald
  • Asscher
  • Marquise
  • Oval
  • Radiant
  • Pear
  • Heart
  • Cushion

All shapes are stunning in their own right. If you like dainty yet striking styles, pear or marquise are good options to go for. Take a look at celeb engagement rings by 77 Diamonds to get a good idea regarding these styles. Heart is an evident representation of love and is ideal for a romantic gift. Emerald and princess diamonds are ideal for those who want a bold and modern diamond. However, if you are a traditional type of girl, go for a round style as this will have more of a vintage edge.

Hopefully, you now have a better understanding regarding what a diamond ‘cut’ is and how it differs from the shape. Happy shopping!
