3-carat cushion-cut diamonds
At 3 carats, a cushion-cut diamond measures approximately 8.0 × 8.0 mm and clearly fills the width of a finger. At this size, it’s worth choosing F to G for color and VS2 or better for clarity, because the surface reveals every detail. Lab-grown diamonds are significantly less expensive than comparable natural diamonds.

What to Look for in Cushion-Cut Diamonds
Check the faceted view and proportions
GIA does not assign a cut grade for cushion cuts, but IGI now does. Also pay attention to polish and symmetry, as well as table and depth. The facet pattern is also important: Coarse, angular facets produce large flashes of light, while the finer “crushed ice” pattern appears more granular and sparkly. Both are correctly cut, but the effect differs significantly, so it’s worth taking a look at a photo or video.
Color and Clarity in the Cushion Cut
The cushion cut retains body color slightly better than a round stone, which is why grades G through H are a good compromise, and grades F through G look more subdued at two carats and above. It is forgiving when it comes to clarity: the finely detailed faceting effectively conceals inclusions, and SI1 is often eye-clean, especially in “crushed ice” stones.
Size in millimeters per carat
A square cushion cut diamond weighing 1 ct measures approximately 5.5 × 5.5 mm; a 1.5 ct diamond measures approximately 6.3 × 6.3 mm; and a 2 ct diamond measures approximately 7.0 × 7.0 mm. The cushion cut has a relatively large amount of weight concentrated in its depth, so it appears slightly smaller from above than an oval of the same weight.
Frequently Asked Questions
How big is a 3-carat cushion?
With an edge length of approximately 8.0 mm and a diagonal of about 11 millimeters, it becomes the defining element of the ring. Compared to a round stone of the same weight, it appears more compact, yet its soft corners give it a less austere look.
What should I look for in a 3-carat cushion-cut diamond?
Focus on depth and the faceted appearance. A very deeply cut cushion cut holds its weight without increasing the outline. Also consider whether you prefer coarse facets or a "crushed ice" look, because with this size, that’s what determines the overall impression.
Lab-grown diamond or natural diamond?
Lab-grown diamonds and natural diamonds are both composed of pure carbon and share the same crystal structure, hardness, and refractive index. The difference lies in their formation: one forms over millions of years in the Earth’s mantle, the other in a matter of weeks in a laboratory. Visually, they are indistinguishable without specialized laboratory equipment. Lab-grown diamonds are significantly less expensive than comparable natural diamonds, which is why, with the same budget, you can often get more carats or a higher clarity grade. Both types come with a laboratory certificate from us; you can look up the report number directly with the laboratory.
