Price
Many factors impact diamond price. With Ritani's Diamond Price Match Guarantee you can be confident you'll get the best price for a diamond. Tip: Tradition tells you to budget 2-3 months' salary for your ring. We say, just do you.
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.
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.

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.
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 by Ritani

Shape

Renowned for their soft, square, pillow-like shape, cushion-cut diamonds feature modern brilliant-cut faceting, giving them a great deal of radiance and fire that superbly reflect white and colored light. Cushion-cut diamonds have the most fire of any cut, radiating bright and colorful flashes of light. They are extremely durable due to their rounded edges and more affordable by carat than brilliant round-cut diamonds. Their squared shape and rounded edges give cushion-cut diamonds an antique appearance that appeals to those who love vintage-style engagement rings. 

For those interested in making a cushion-cut diamond appear larger, a halo setting is recommended to achieve this effect. With a halo setting, the tiny diamonds that encircle your cushion-cut diamond will give the illusion of a larger diamond with added sparkle. Or, let your cushion-cut diamond stand out with an elegant solitaire setting.If you want a traditional square-shaped cushion-cut diamond, choose a diamond with a length-to-width ratio of 1.00 to 1.05. A cushion-cut diamond with an elongated shape will have a length-to-width ratio of 1.06 to 1.10.

All Ritani earth-grown diamonds are certified by the AGS or GIA—the world’s most respected independent grading labs. If you need help selecting your cushion-cut diamond, contact us at 1-888-9RITANI or chat now!
