One of the biggest mistakes people make is believing that the cut refers to the shape of the diamond. This is not the case. The cut does not refer to the shape the diamond has been made into but rather it relates to how well the diamond has been cut from its rough form. It is more to do with overall quality and proportions. It is one of the most vital aspects to take into account when buying a diamond, but, unfortunately, it can also be one of the most confusing. But, don’t fret, as we have put together this handy guide.

The reason why the cut of the diamond is so important is because it has the all-important role of determining the scintillation, fire, and brilliance of the diamond. Or, in basic terms, how well the diamond sparkles! If you can see someone’s diamond ring twinkling from across the room, you know the cut is an exceptional one.

Diamond Cut

What makes a good diamond cut? Well, one of the most considerable factors is the proportion of the diamond, which refers to the relationship between the angle, shape, and size of every facet in the diamond. This is complex business when you consider that some diamonds have more than 50 facets. If the diamond is cut too deep or too shallow, the light will escape through the bottom of the diamond. The diamond needs to be cut in a way that ensures the light strikes each pavilion facet at the right angle so that the majority of the light is reflected. You can discover a bit more about this under the ‘anatomy of a diamond’ section.
