What diamond cut is best for my engagement ring?

What diamond cut is best for my engagement ring? Cut is important, because it influences the style of your ring and the radiance of the diamond. Here we take a look at the different diamond cuts and shapes, their benefits, and the types of hands they suit.

What does ‘diamond cut’ mean?

‘Diamond cut’ refers to two things:

  1. Firstly, how well your diamond sparkles
  2. Secondly, what shape your diamond is

What cut quality should I look for?

Cut quality determines how well your diamond plays with light.

Don’t worry, your jeweller will simply tell you what ‘cut quality’ your diamond has.

As a rule of thumb, look for a minimum “good” cut for diamonds up to 0.50CT. A “very good” or an “excellent” cut is advised for larger stones.

What diamond shape should I look for?

Different diamond shapes offer varying levels of brilliance and fire.

They can also suit different hand shapes.

Here are the most popular ones…

What diamond cut is best for my engagement ring? 7 Best cuts

1. Round cut 

The most popular cut and also the sparkliest of all diamond shapes. Most of the rough diamond is lost when cutting and therefore round diamonds are slightly more expensive than other diamond shapes. Over 75% of diamond engagement rings sold are round cuts. Available in many sizes, the round suits all hand sizes and shapes, because it always looks proportionate and does not overpower the finger.


2. Princess cut

First introduced in the 1970’s, the princess cut diamond is square. Just like the round cut, it has a a large number of facets and offers exceptional sparkle. It’s a modern alternative to the round cut. Its square shape easily disguises inclusions, meaning it looks beautiful in all carat sizes. It flatters all types of hands. Its geometric shape tends to appeal to those who like contemporary jewellery.

3. Emerald cut

This rectangular cut offers long, sustained flashes of light – as opposed to the overall sparkle of round or princess cut diamonds. It has large facets, which notably create a ‘box of mirrors’ effect when you peer inside the stone. A vintage cut, it has become more and more popular in recent times. The emerald cut has a slimming and elongating effect on the fingers, making it a perfect shape for someone with wide, short hands.

4. Marquise Cut

The marquise cut is a tapered cut, like two half circles joined together. If you’re looking for a sophisticated cut to slim and elongate the finger, the marquise diamond could be for you. Dating back to the 18th century, the name marquise is derived from the title that was above a count; courtiers used to wear marquise cut diamonds as a symbol of their rank. The large, long surface area makes the diamond look bigger than it actually is and offers unique style


5. Oval Cut

Much like the round cut, oval cut diamonds offer outstanding brilliance and fire. Although a little less traditional than the round cut, oval cut diamonds look good on all hand shapes. Those who are looking for the incredible sparkle and classic elegance of round diamonds, but want something a little out of the ordinary, should buy the oval cut. It also gives the illusion of being larger than it actually is, due to its elongated shape.

6. Pear shape

A stunning combination of a marquise and oval cut, resembling a tear drop, the pear shaped diamond was created to offer maximum brilliance and fire. Pear shaped diamonds first date back to the 1450’s. Also known as a tear drop diamond, due to its rounded bottom and single point top, the pear cut is regarded as a glamorous vintage-style cut. While it suits most hand types, it’s particularly great for someone with shorter hands, as it appears to elongate the finger.

7. Cushion Cut

The cushion cut is a square cut with rounded corners. Before the round cut came along in the beginning of the 20th century, it used to be the most sought-after diamond style. Combining a vintage feel with modern brilliance, cushion cuts really grab the eye thanks to their substantial inner fire and sparkle. This cut is suited to brides who like lavish vintage looks and is flattering on wide fingers.

In conclusion – What diamond cut is best for my engagement ring? 

Ultimately, all cuts are unique and beautiful in their own way and your final decision is down to personal preference. If unsure, however, we would advise you to go for a classic round brilliant cut diamond solitare ring with a minimum cut quality of good or very good. It’s the most popular diamond shape ever thanks to its superior brilliance and versatility.
