Regarded as the third popular cut of diamonds, cushion diamond stones have better fire and larger variance generated by 68 facets. Often referred to as the “pillow” or “candlelight” diamond cut, it is the vintage take of round cut diamonds but has a softer radiance with rounded corners. Our stone sizing chart below shows the standard sizes and matching carat weights for cushion-cut diamonds to help you find your perfect fit.
