Cushion Cut Engagement Rings
Cushion cut engagement rings have gained popularity, thanks to the elegant design and lower cost. As a square cut with rounded corners, it offers durability with a modern flair. Cushion cuts can be set in almost any ring style, but are especially common in halo engagement rings.
For cushion cut diamonds, we recommend depth and table percentages below 70%. These measurements ensure light reflects off of the table and back to the eye. Cushion cuts retain a large amount of color, so we recommend an H grade or better. For Clarity, look for an SI1 or SI2 graded diamond for the best value.
Different than other shapes, Cushion Cuts come in variations, including standard, modern and modified. Cushion Cuts are usually square but you can find rectangle stones as well. For square diamonds, look for a length to width ratio between 1.0-1.09. For rectangles, aim for 1.15-1.25.
