Question 1

How much is a cushion cut engagement ring?

Accepted Answer

A cushion cut engagement ring costs the setting plus the diamond. The setting price depends on the style and the metal; platinum costs more than 14K gold. The diamond price depends mostly on carat weight. Because diamond prices change daily, we show today's live prices below instead of a fixed figure.

Color, clarity and cut move the price too. See today's prices: 1 carat cushion · 2 carat · cushion settings

Question 2

How big is a cushion cut diamond at each carat weight?

Accepted Answer

A cushion's size depends on its carat weight and whether it is cut square or elongated — the length-to-width ratio changes the millimeters a lot. An elongated 1 carat cushion measures about 7.5 × 5.1 mm and a 2 carat about 9.2 × 6.9 mm. A square cushion of the same weight is shorter and wider.

Typical sizes in current lab stock:

1 carat, elongated (ratio ~1.45) — about 7.5 × 5.1 mm
1.5 carat, elongated (ratio ~1.45) — about 8.5 × 5.9 mm
2 carat, elongated (ratio ~1.35) — about 9.2 × 6.9 mm
3 carat, square (ratio ~1.0) — about 8.2 × 8.0 mm

A square cushion is shorter and wider than an elongated one of the same weight, so compare the length-to-width ratio on each stone, not just the carat. Browse by size: 1 carat · 2 carat

Question 3

What is the difference between a square and an elongated cushion?

Accepted Answer

A square cushion has near-equal length and width, so it looks full and classic. An elongated cushion is stretched a little longer, so it looks longer on the finger and can slim the hand. Both keep the cushion's soft rounded corners and bright fire; the choice is personal taste.

Question 4

Which setting styles suit a cushion cut diamond?

Accepted Answer

You can set a cushion in almost any style. A halo is the most popular on cushions — it echoes the soft shape and adds sparkle. Solitaire shows the whole stone, three stone adds width, and vintage detail suits the cushion's romantic look. Every setting in the grid above is made for a cushion.

Question 5

Which metals can I choose for a cushion cut engagement ring?

Accepted Answer

Every cushion setting comes in platinum or in 14K or 18K gold, in yellow, white or rose. Rose gold is a popular pairing with a cushion's soft shape. Yellow and rose gold look warm, so a slightly warmer diamond looks natural in them. White gold and platinum look bright and cool.

14K or 18K? 18K is 75% gold and has a richer color. 14K is 58.3% gold, so it is a little harder. Browse rose gold cushion settings →

Question 6

What wedding band goes with a cushion cut engagement ring?

Accepted Answer

It depends on the setting height. A straight band sits flush under a higher cushion solitaire. If your cushion has a halo or sits low, a curved or contoured band that follows the setting closes any gap and fits more comfortably.
