Square Cushion Diamond Engagement Rings
A square cushion diamond pairs a balanced, almost square outline with softly rounded corners, creating a romantic shape with rich visual character. With its softly rounded corners and balanced proportions, a square cushion brings together the structure of a square with the gentle curves of a more traditional diamond shape. What makes a square cushion especially beautiful is the variety of faceting styles available. A thoughtful setting can highlight the shape without overpowering its natural character.

Square Cushion Diamonds Explained
What is a square cushion diamond?
A square cushion diamond is a diamond with four softly rounded corners and a nearly equal length and width. Its outline resembles a pillow, which is where the cushion cut gets its name. Unlike a princess cut, which has sharp corners, a square cushion has a softer silhouette that gives it a romantic, timeless appearance.
How is a square cushion different from a princess cut diamond?
Both diamonds have square proportions, but their outlines and faceting are quite different. A princess cut features sharp, pointed corners and angular brilliance, while a square cushion has rounded corners and a softer silhouette. Cushion diamonds also come in several faceting styles, allowing for a wider variety of visual appearances.
What is the ideal length-to-width ratio for a square cushion diamond?
Square cushions typically have a length-to-width ratio between 1.00 and 1.05. A ratio of 1.00 creates a perfectly square outline, while slightly higher ratios introduce a subtle elongation that may be barely noticeable to the eye.
What is the difference between crushed ice and brilliant faceting?
Crushed-ice cushions display numerous small, scattered reflections that create a shimmering appearance. Brilliant-style cushions with larger, more defined facets tend to produce broader flashes of light and a more structured pattern. Neither is inherently better. The choice depends on whether you prefer a delicate shimmer or more distinct flashes of brilliance.
What settings work best with square cushion diamonds?
Square cushions work beautifully in classic solitaires, hidden halos, three-stone designs, and vintage-inspired settings. A delicate band can emphasize the diamond’s softly rounded outline, while a bezel or more architectural setting creates a contemporary contrast. The beauty of a square cushion is its ability to adapt to almost any design aesthetic.
