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.
Round Brilliant Shape Diamond Cut
Containing 58 facets, including the culet, the round brilliant diamond shape is one of the most popular choices for engagement rings, thanks to its superior sparkle. A round dimming cut will work with almost every setting, from simple solitaires to intricate vintage styles and is perfect for those who prefer a classic shape.
Cushion Shape Diamond Cut
The cushion cut diamond combines the modern look of a square cut diamond with soft, rounded edges for a cushion shape. It is excellent at reflecting light and has a high level of brilliance. This cut has been around for over 200 years and is still just as popular today as it was when it was first created, giving it a timeless look and feel.
Princess Shape Diamond Cut
After the round brilliant, the princess shape is the most popular style as it has the same amount of facets, which means it sparkles and shines just as brightly as a round, but has square, clean lines to give it a more modern look.
Heart Shape Diamond Cut
Ideal for the ultra-romantic, the heart-cut diamond is the ultimate symbol of love as it resembles a heart shape. Containing between 56-58 facets, this diamond can reflect lots of light for a fantastic sparkle. But, similar to a pear cut and a marquise cut, the facets need to be symmetrical for the best sparkle possible.
Pear Shape Diamond Cut
A pear-cut diamond is an unusual shape with rounded edges that join at a tapered point. Feminine and elegant, this style will help to elongate the look of someone’s fingers and is ideal for those who want something a little different. With 58 facets, light dances through a pear-cut diamond beautifully, however, they have to be symmetrical to achieve a great sparkle.
Emerald Shape Diamond Cut
The emerald-cut diamond was one of the first diamond cuts in the world. With layered faceting, the emerald cut offers a unique sparkle and is known for being one of the most sophisticated and regal cuts. Because of its larger surface area, inclusions are often easier to spot, so it's recommended to choose a higher-quality diamond for this shape.
Oval Shape Diamond Cut
A favourite among royals such as Princess Diana, Kate Middleton and Meghan Markle, the oval cut diamond contains 56 facets in a similar pattern to the round brilliant. This means it has the brightness of a brilliant cut when cut well. Thanks to its elongated shape, it will also accentuate long and slender fingers.
Asscher Shape Diamond Cut
The asscher cut diamond is a variation of the emerald cut as it has a square shape but with distinctive cut corners to give the stone a geometrical feel. While this cut isn’t the sparkliest, it’s renowned for its clarity and lustre and has a highly sophisticated, vintage appearance.
Marquise Shape Diamond Cut
The marquise cut has a slender shape with pointed ends and can help the diamond cutter maximise the carat within the setting - this means that it will look larger even when next to a diamond of the same carat weight. With 56 facets, it also boasts fabulous sparkle and brilliance.
Radiant Shape Diamond Cut
The radiant cut diamond combines the classic emerald cut with the sparkle of the round brilliant, so you get the best of both worlds. Radiant cuts can be either square or rectangular with rounded corners and feature 70 facets to give them their amazing ability to reflect light and create a gleaming sparkle.
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.
