Cushion Buying Guide

A cushion cut diamond combines the modern round brilliant cut pattern with the classic old mine facet style. Typically featuring 58 to 64 facets, these diamonds are characterised by their rounded corners, giving them an elegant, pillow-like appearance. They also showcase vibrant colours from within the gem when viewed from various angles.

Cut

The standards for cushion cut diamonds can vary considerably from other shapes, making personal preference a crucial factor in selecting the right one.

There are two types of cuts for the cushion diamonds. Cushion brilliant and cushion modified brilliant. This terminology still is confusing to the seasoned jewellery veterans. In simpler terms, we like to explain it as a crushed ice look or distinct faceting. Theres no “one is better than the other” situation, people like both! Just a matter of which is more appealing to the eye of the beholder.
Please see examples of both below

Colour

Cushion cut diamonds tend to display more colour compared to round brilliants, but their brilliance and dispersion can help mask this colour. Therefore, we recommend choosing a colour grade of G or higher.

Clarity

Most VS2 and SI1 cushion cut diamonds will appear eye-clean, as their inclusions are often concealed by the diamond's sparkle and scintillation. However, it is crucial that the diamond is well-cut. Cushion cuts feature a large, open table, making it challenging to find an eye-clean SI2. When considering SI1 and SI2 diamonds, carefully examine the stone to ensure that any imperfections are not large, dark, or located at the centre.

For a square cushion cut, we recommend a length-to-width ratio where the length is between 1.00 and 1.09 times the width. For a more rectangular cushion, opt for a diamond where the length is between 1.15 and 1.50 times the width. The most popular shape is a slightly rectangular cushion with a length approximately 1.10 to 1.20 times the width.
