Cushion-Shaped Diamonds

Taking the best from both worlds, cushion-shaped diamonds feature large facets that increase brilliance and rounded angles that contribute to a romantic look. A favorite of stylish women for over a century, these timeless stones won’t be going anywhere soon. Because their exact shape and facet patterns can be chosen as well as their settings, cushion diamonds are some of the most customizable diamonds for engagement rings.

Cushion-Shaped Diamonds - The 4 C’s

Cut — The shape of a diamond refers to its physical appearance, while the cut refers to how well the diamond’s features interact with light. Because cushion diamonds are a “fancy” cut, they are not graded. However, cut is still important when it comes to cushions; you can choose whether you would prefer an “antique” cushion diamond with defined facets inside or a “crushed-ice” cushion diamond with disorganized sparkles inside.

Clarity — Cushion diamonds do not need to be scrutinized for clarity, which refers to the amount of inclusions and blemishes in a stone. Each diamond will have a different amount of these flaws, ranging from SI2 (having the largest amount) to VVS1 (having the least). Because of the shape and cut of cushion diamonds, they will hide most inclusions—especially if you choose the crushed-ice facet style as opposed to the antique style.

Color — When you’re examining diamond choices, color refers to the absence of color. Clean Origin only offers diamonds from J to D, though there are diamonds with color from Z (containing the most color) to D (containing the least color). More than most shapes, cushion diamonds retain their color. If you decide to match your cushion diamond with a white gold or platinum band, stick to H or higher color grade.

Carat — Cushion diamonds can look slightly larger than their actual carat weight due to their larger facet sizes, and they can be made to look even larger by adding a halo to surround the center stone. If a halo doesn’t add enough oomph to your small diamond, a lab-grown diamond will save you 20-30% on the price, allowing you to increase carat size without breaking the bank.

Buyers Tips for Cushion-Shaped Diamonds

Two main factors of cushion-shaped diamonds are customizable: the stone’s facet pattern and exact shape. “Antique” or “chunky” and “crushed ice” cushion diamonds are your two facet choices, neither claiming any status over the other. With the antique style, you’ll see clearly defined facet patterns within the stone, while with the crushed-ice style, you will see what looks like broken glass or crushed ice. Size is another item you can customize: While traditional cushion diamonds are made in a perfect square, they are made in rectangular shapes as well. Currently, the 1.1–1.2 length-to-width ratio is popular, but your loved one’s preferences should inform your final choice.

Lab-Grown Cushion-Shaped Diamonds

Lab-grown cushion-shaped diamonds have identical chemical constructions and appearances to mined diamonds. When comparing the two, you will look for the same qualities in clarity, color, and carat. Both types offer the antique or chunky and crushed-ice styles, and both square and rectangular shapes. However, because lab-grown cushion diamonds rely on a shorter supply chain, they can offer the same qualities as mined diamonds at a 20-30% lower price, empowering you to add that extra carat, halo, or pavè while staying within your budget.

Often confused with cut, the shape of a diamond is the physical appearance that it takes. The most popular shape is the round brilliant.
The cut of a diamond determines how effectively light that enters the stone is refracted within and reflected back through the top of the diamond, providing sparkle. The best cut grade is defined as Ideal, followed by Excellent, Very Good, Good, and Fair. Fancy shape stones often do not receive cut grades and will be listed as 'None.'
Carat refers to the actual weight of a diamond and is a unit of measure equal to 0.2 grams. In all diamonds, carat weight is a large contributor to the price of the stone.
The color in diamonds is actually the absence of color, graded on an alphabetical scale from D to Z, with D being a colorless diamond and Z being yellow.
Clarity measures the amount of inclusions or imperfections found in a diamond. The best clarity is VVS1 followed by VVS2, VS1, VS2, SI1, and SI2. Although other levels of clarity exist, we only carry diamonds with quality we can stand behind.
