Cushion

Cushion shaped diamonds are just that: pillowy looking stones with rounded corners. They can be either square in ratio or slightly elongated.

They tend to be deeper than other shapes with a higher table. But they are also more affordable, making them a great alternative to a round diamond.

No matter what shape of diamond you’re looking at, these are a few other considerations to take into account:

• Who certified the diamond? Some companies sell diamonds that were graded by in-house gemologists; we strongly believe it is best if a diamond is graded by a third-party lab such as GIA, IGI, or GCAL. GIA tends to have stricter standards than the other two labs. This does not mean non-GIA graded diamonds are undesirable, but rather it just means you may not be comparing apples to apples if you’re looking at stones graded by different labs.
• Are any inclusions visible to the eye? In diamonds with VS2, SI1 and SI2 (and below) clarity grades, there may be small imperfections that are visible without a loupe. The details of those inclusions matter. if they’re in a corner that can be covered by a prong, for example, or if the inclusion is a white feather, it won’t impact the final look of your ring and that stone is likely a great buy. 
• Is there fluorescence present? Generally with higher colors, it is better to have less fluorescence, because fluorescence often results in a less lively stone. However, fluorescence can also help warmer colors look whiter on their face.
• How is the symmetry and polish graded? A top grade on both will contribute towards the diamond’s overall brilliance and shine.
