When you think of diamonds, you always think of them shimmering brilliantly, but they can only become so visually stunning thanks to the way that they’re cut.

This is the only one of the four Cs that’s directly affected by human intervention and it can make all the difference.

It can ensure that the brilliance, fire and scintillation are heightened to their maximum level so that the diamond is truly breathtaking.

There’s even a mathematical formula for working out how to perfectly cut a diamond ‚Äď it was developed in 1919 and has been modified over time to take into account new techniques in diamond cutting.

A diamond with the ideal cut is given a grading of excellent, as light bounces through the diamond’s angles back towards the viewer.

Very good diamonds offer marginally less scintillation and brilliance, but the difference is virtually unnoticeable to the naked eye.

When a diamond has a good cut, some of the light escapes through other areas, but again the difference isn’t too great.

However, if a diamond’s been cut too deeply or too shallowly, much less light is reflected back to the eye and the difference between these fair or poor cuts and excellent ones can be noticeable.

While diamonds with an excellent cut are the most sought after, if your budget won’t stretch to one, consider looking at stones with slightly deeper or narrower cuts – these can still look amazing, but won’t cost as much as the ideal cut options.
