Jewellery Guide: Diamond Cuts

There are a lot of different styles of diamond cuts and choosing the right one is one the main things to consider whether you are looking to buy and engagement ring or any piece of diamond jewellery. For this post I am going to take you through the most popular diamond cuts that are available in the marketplace.

The Round Brilliant Cut

Modern Round Brilliant Cut Diamond

The modern round brilliant cut is by far the most popular diamond cut and consistently outsells all other cuts. The evolution of the round brilliant goes back hundreds of years and can be traced all the way back to when they first started polishing diamonds and no other cut has had the level of research and development to create the perfect cut diamond as the round brilliant and is the standard by which all other cuts are judged. When cut to the ideal proportions, no other cut can compete with the fire and brilliance that is seen in round brilliant and when matched with good colour and clarity, you will be looking at diamond perfection.

Princess Cut

The second most popular choice of diamond cut is the princess cut. The popular square shape can be traced back to the early 1970’s but the final princess design was completed in 1979 and it is a modified version of round brilliant cut. Unlike the round brilliant, there can be some variations in the princess cut as the facet layout and design can vary between diamond cutters. Care must be taken with a princess cut as the points of the diamond can be quite fragile, so the right type of setting that protects the corners is a must.

Cushion Cut

The cushion cut was a style of cut that was liked by a few people but was not an overly popular choice, until November 2017. What happened in November 2017, the 27th of November to be exact? On this day it was announced that Prince Harry was engaged to Meghan Markle and the beautiful engagement ring had three cushion cut diamonds set in 18ct yellow gold. In the time since, the popularity of cushion cuts went through the roof. The modern cushion cut is a modification of the round brilliant cut.

The round brilliant cut design is also used a base for a variety of other cut styles. Going from left to right is the Pear Cut, Oval Cut, Trillion Cut, Heart Cut, Marquise Cut and the Radiant Cut.

Step Cuts

Step Cut Diamonds

Step cuts are another style of diamond cut that are perfect for higher quality diamonds. Due to having a large window going in to the stone, any imperfections or strong colouration in the stone will be evident so this cut reserved for stone with good clarity and colour. As the stones do not have as many facets, they do not sparkle as much as the brilliant cut stones and can look a little bit dull in comparison. The most popular styles of the step cut are the baguette (left), asscher (middle) and emerald (right).

You can also find some old style cuts, which are very popular with people who like antique jewellery. The two most popular styles are the old european cut which was the first style of diamond to ever be round, however the cut quality can be quite poor when compared to modern cut diamonds. The other style that is quite rare to find is the old mine cut, the shape is similar to that of the cushion cut but as with the old european, the cut quality can vary quite a lot from stone to stone as much of the cutting was done by eye.
