Cushion cut engagement rings have a long history as the traditional diamond cut. This old favorite, now considered a classic, never goes out of style.
A cushion cut, also known as a pillow cut engagement ring, has been around for nearly 200 years and is derived from old mine cut diamonds. The cushion cut evolved from an antique cut known as a "candlelight diamond" because of its broad facets, intended to shimmer in candlelight before electricity was used as a means of lighting.
A cushion cut ring is named after the square diamond shape with softly rounded corners that give them a pillow, or as the namesake implies, a cushion appearance. The soft, rounded edges imbue a gemstone with a sense of romance and opulence.
A critical aesthetic option in a cushion-cut diamond is whether you want it to be square or rectangular. Cushion engagement rings come in various proportions. Some are more long and narrow, and some are more circular. Though square gemstones are the most common shape, rectangle cushion cut engagement rings benefit from appearing larger than their carat weight.
When it comes to cushion cuts, the length-to-width ratio (L/W) is essential to consider.
The L/W ratio of square shapes should be between 1.00 and 1.05. Rectangular forms should be elongated considerably, but not excessively, with an L/W ratio of 1.15 to 1.20. When purchasing cushion cut engagement rings, try to avoid the ratios between 1.06 to 1.10.
