Cushion Cut Diamond

The cushion cut is a brilliant-cut diamond with a square or rectangular outline and softly rounded corners. It exists in two main variations: the "cushion brilliant" with a facet pattern similar to a round brilliant, and the "cushion modified brilliant" which features an extra row of facets below the girdle that creates a different light pattern, sometimes described as a "crushed ice" appearance. The cushion cut typically has 58 facets and is celebrated for its exceptional fire — the ability to break white light into spectral colours. In fact, the cushion cut often displays more fire than a round brilliant.

The cushion cut's predecessor, the "old mine cut," was the most common diamond shape from the 1700s through the early 1900s. Old mine cuts were hand-cut by candlelight and feature a high crown, small table, and large culet visible through the top of the stone. The modern cushion cut evolved from the old mine cut with improved proportions and precision cutting. Its romantic, vintage character has fuelled a major resurgence in popularity, with the cushion cut now ranking among the top three most requested engagement ring shapes.

First, decide whether you prefer a classic cushion brilliant (larger, more defined facets with bold flashes) or a modified cushion brilliant (smaller facets creating a "crushed ice" sparkle). Neither is better — it is purely personal preference. For square cushions, look for a length-to-width ratio of 1.00-1.05. Colour can be slightly more visible in cushion cuts, so aim for H or better. Clarity of VS2 is generally sufficient for an eye-clean stone. Lab-grown cushion cuts offer excellent value, particularly in larger sizes.

Cushion cuts look beautiful in halo settings, where a frame of smaller diamonds complements the shape's rounded corners and adds size. A four-prong solitaire showcases the cushion's soft shape elegantly. Vintage-inspired settings with milgrain detailing and side stones enhance the cushion's romantic character. Three-stone settings with half-moon or trapezoid side stones create a sophisticated, balanced design.

The cushion cut appeals to romantically inclined buyers who love vintage aesthetics but want modern sparkle. It is popular among those who appreciate the warmth of colourful fire over pure white brilliance.
