An elongated cushion cut diamond has a rectangular shape with rounded corners, as opposed to a square cushion which is more equal in length and width. This cut retains the hallmark soft, rounded corners of a cushion cut but with a longer length-to-width ratio.

Cushion cut and elongated cushion cut diamonds share the same faceting style, rounded corners, and overall "pillow-like" appearance. The key difference lies in their length-to-width ratio or proportions.

If you're choosing between a cushion and elongated cushion lab grown diamond, think about your style and hand shape. Elongated cushions offer a more modern look and, for some, can create the illusion of longer fingers, but the best shape is always the one that feels right for you.

An elongated cushion cut lab grown diamond may be the perfect choice for an engagement ring that makes your style your own.  If you’re still deciding, browse our collection of cushion and elongated cushion diamonds to explore the differences and see what catches your eye.

Due to its proportions and larger face-up surface area, an elongated cushion cut diamond can appear larger than other shapes of the same carat weight.

Pros:

• Unique, Modern Appearance: The elongated cushion cut stands out for its elegant, trendy look that blends vintage charm with a contemporary twist.

• Flattering on the Finger: The elongated shape creates the illusion of longer, slimmer fingers and offers more finger coverage than square shaped diamonds or round diamonds.

• Illusion of Size: Due to its proportions and larger face-up surface area, an elongated cushion cut can appear larger than other shapes of the same carat weight.

• Excellent Fire and Brilliance: With 58–64 facets, this cut offers a soft, romantic sparkle with broad flashes of brilliance and fire, often described as a "romantic glow".

Cons:

• Harder to Find: Elongated cushion cut diamonds can be harder to find because most retailers don’t label them separately from standard cushion cuts. They're usually listed simply as “cushion,” which makes it more difficult to filter for the elongated shape. At Clean Origin, we clearly label elongated cushion cuts to make your search easier.

• Potential for Bowtie Effect: The bowtie effect is a common visual trait in elongated cushion cut diamonds and other longer-shaped diamonds. It occurs due to the way light reflects within the diamond’s proportions and facet structure. The visibility of the bowtie can vary between diamonds. It is not a flaw, but simply a natural characteristic that appears in some elongated shapes.

Whether you prefer a classic design, a timeless solitaire, a vintage-inspired look, a clean minimalist style, a bold three-stone ring, or a sparkling halo, there’s no wrong choice, it’s all about what feels right to you.
