Carat
Carat is the measure of a diamond's weight and size. We offer an array of high-quality diamonds ranging from 0.18 to 25.00 carats- with 1.00 carat being the most popular.
Min
Max
Color
A diamond’s color grade actually measures how little color it reflects. To strike the best balance between cost and beauty, go for diamonds in the Near Colorless range: G, H, and I.
Clarity
Clarity indicates how many flaws are visible to the naked eye. Too many flaws can detract from a diamond's beauty.
Cut
Cut is the quality of a diamond’s proportions and symmetry. The better a diamond’s proportions and symmetry, the more sparkle it will produce. Cut is the most important of the 4 Cs.
Polish
A well-polished diamond will have excellent light return.
Fluorescence
Some diamonds glow blue or green when exposed to UV light. Since fluorescence is rarely visible, it has minimal impact on the appearance of your diamond. To save money, go for medium fluorescence.

Depth %
Depth percentage correlates with a diamond's sparkle factor. It is measured by dividing the diamond height by its diameter. For maximum sparkle, the depth percentage of a round diamond should be between 54% and 66%.

Length/Width Ratio
The proportional relationship between your diamond’s length and width. A perfect round diamond would measure equally 1-to-1, so its LxW ratio would measure as 1.

Symmetry
Symmetry tells you how well a diamond’s facets align to create sparkle. Diamonds with perfect symmetry create the most sparkle and earn a grade of Excellent or Ideal.
Table
Table percentage tells you how big a diamond’s topmost facet (aka table) is in comparison to its diameter (aka girdle). When that ratio is in the right range, a diamond will sparkle more.
Min

Culet
The culet is the point at the bottom of the diamond. If the point has a facet on it, it can stop light from reflecting and detract from the diamond's sparkle. Choose a diamond with no culet for optimum sparkle.
Certificate
All of Ritani’s natural diamonds are certified by either the GIA or AGSL, the industry’s two most respected grading labs.

Cushion-Cut Diamonds

Why Choose a Cushion Cut Diamond?

Cushion cut diamonds have remained one of the most beloved diamond shapes for more than a century. Combining the elegance of a square shape with softened corners, cushion diamonds offer a romantic look that feels both classic and contemporary. Their distinctive silhouette makes them a popular choice for engagement rings, especially among shoppers looking for a unique alternative to a round brilliant diamond.

One of the most appealing characteristics of a cushion cut diamond is its exceptional fire. The larger facets of a cushion diamond create beautiful flashes of colored light, giving the stone a warm and captivating appearance. Depending on the cutting style, cushion diamonds can display either a crushed ice effect with abundant sparkle or a more defined facet pattern with bold brilliance.

Cushion cut diamonds are available in both square and elongated proportions. Square cushion diamonds offer a balanced, symmetrical appearance, while elongated cushion cut diamonds can create the illusion of longer, more slender fingers. Both styles pair beautifully with solitaire, halo, hidden halo, pavé, and three-stone engagement ring settings.
Because cushion cut diamonds retain more of their original rough diamond during the cutting process, they can often provide excellent value compared to other popular diamond shapes. Shoppers may be able to maximize carat weight while enjoying a distinctive and elegant look.

Browse our collection of cushion cut diamonds to find a timeless diamond shape that combines vintage charm, remarkable sparkle, and exceptional value. Whether you're designing a classic engagement ring or a one-of-a-kind jewelry piece, a cushion cut diamond offers beauty that never goes out of style. All Ritani earth-grown diamonds are certified by the AGS or GIA—the world’s most respected independent grading labs.
