Soft corners, vintage glow
The cushion cut descends from the old mine cuts of the 1800s, with rounded corners and large facets that give chunky flashes of light rather than fine pin-point sparkle. Square cushions look classic and romantic; elongated cushions around 1.15 to 1.30 look more modern and slightly larger on the hand.
Choosing a cushion
Cushions are sold in two faceting styles: "crushed ice", with many small facets that look glittery, and "brilliant" or "antique", with fewer, larger facets. Because cushions retain more color in their corners, we recommend E or F color or better if you choose a white metal. A halo setting suits a cushion beautifully, echoing its rounded outline and adding extra brilliance.

Why choose a cushion diamond?
Cushion diamonds have soft rounded corners and a romantic, pillow-like outline with lively sparkle.
How to choose
Start with the look you love, then pick the metal that matches your style and the diamond size that fits your budget. Prices in this collection range from $484 to $5,649.
Are lab grown diamonds real?
Yes. Lab grown diamonds are made of pure carbon with the same crystal structure, hardness and sparkle as mined diamonds, and they are graded on the same color, clarity and carat scales. They typically cost 70 to 90 percent less and have a traceable, conflict-free origin.
Sizing, care and custom requests
Every piece is made to order, so you can choose your ring size, metal and, on many designs, the diamond size and quality. Clean your jewelry with warm water, mild soap and a soft brush, and store it separately to avoid scratches. Want a change to a design? Contact our team for a custom quote.
