What Diamond Cut is the Best?

While all diamond cuts are marvellous in their own way, by far the most popular and most sought-after diamond cut is either the excellent or very good cut. Both of these cuts will achieve superb sparkle. While other grades, such as carat, colour and clarity, can be compromised since colour and clarity can be better concealed, the cut is one grade you want to ensure is the absolute best. This is because a low-cut diamond grade will result in a diamond that doesn’t sparkle as brightly.

When it comes to diamond cut, we would always recommend filtering your searches to only excellent or very good grades and sacrificing on carat or colour if needed, as there is no hiding a lower cut grade. At Sacet, we only sell excellent, very good or good diamond cuts.

Types of Diamond Cuts

Wondering what the other types of diamond cuts are? Here, we’ll explain the cut grading chart and what makes each one different.


Excellent Diamond Cut

Excellent cut diamonds have the highest level of fire and brilliance because it reflects almost all of the light that enters the diamond, making it dazzle like no other.

Very Good Diamond Cut

A very good cut diamond reflects most of the light entering the gem, which offers stunning brilliance and fire. To the naked eye, this cut is very similar to the excellent cut but is often priced much lower.

Good Diamond Cut

While good cut diamonds still reflect most of the light that enters, the diamond will not have the same sparkle and brilliance as the grades above. However, they are still beautiful diamonds but at a much lower price point.

Fair Diamond Cut

Fair cut diamonds reflect a small portion of the light that enters as the diamond is usually cut too deep or too shallow. Because of this, they offer little brilliance and are more likely used as side stones rather than the main stone in a piece of jewellery. At Sacet, we don’t sell fair cut diamonds.

Poor Diamond Cut

With poor cut diamonds, the entering light typically escapes from the sides and bottom of the gem rather than reflects, meaning they create nearly no sparkle, brilliance or fire. Again, at Sacet, we won’t sell any poor cut lab-grown diamonds.

Types of Diamond Shapes

Here, we’ll also explain the most popular types of diamond shapes, as this often gets confused with the diamond cut.


The diamond colour refers to the absence of colour in the diamond itself. The whitest or colourless a diamond is, the more light will pass through the stone to create extraordinary sparkle.

The clarity of a diamond refers to the purity, or cleanliness, of the stone. This is determined by the number of inclusions a diamond might have by a trained gemologist using a 10x magnification glass.

The carat of the diamond is a unit of mass used to measure the weight of the diamond, not the size. Each stone is weighed individually, and one carat is equivalent to 200 milligrams or 0.2 grams.
