Lab Diamond Elongated Cushion Cut Engagement Rings

About This Shape

The elongated version differs from the standard square through its length to width ratio, typically between 1.15 and 1.30. This rectangular style combines soft rounded corners with an elegant stretched silhouette. The cut diamond features brilliant faceting that maximises light return and creates exceptional sparkle. It appeals to those who want something distinctive yet timeless.

Setting Styles

A solitaire style showcases the shape beautifully, with four prong or six prong settings being most popular. Halo designs add extra presence and can make the centre stone appear larger. Three stone arrangements with tapered baguettes create an Art Deco inspired look. The elongated cushion cut ring works well in both classic and contemporary mount styles, offering versatility for every taste.

Lab Grown Options

Our lab grown pieces offer the same optical properties as mined stones. Each cut diamond comes with independent certification confirming clarity, colour and carat weight. Choosing lab grown allows you to select a larger stone or higher grade within your budget. This option represents exceptional value without compromise on beauty.

Choosing Your Stone

Look for a length to width ratio that appeals to your eye. Some prefer a subtle stretch while others want a more pronounced rectangular style. Clarity of VS2 or above ensures a clean appearance. For colour, G or better works well in white metal settings. The elongated cushion cut diamond ring you choose should balance these factors against carat weight for the best overall appearance.
