Cushion cut diamonds are less expensive than rounds because they waste less rough crystal. Also, because they are less in-demand than round or princess cut diamonds, they tend to cost less, too! This means that choosing a cushion cut diamond offers you not only super sparkle, but great value, too.

Round is the most expensive diamond shape, so round cut diamonds are more expensive than cushion cut diamonds. Wondering how these shapes compare in price? On average, a cushion cut diamond will cost 25% to 50% less than a round cut diamond with the same carat weight and qualities.

Tiffany, 27, showed off her legs in a teal cocktail dress that featured a thigh-high slit, which she paired with her 13-carat emerald-cut diamond engagement ring that is believed to be worth up to a staggering $1.2 million.

So how much more affordable are cushion cut diamonds than round diamonds? Assuming two cushion cut and round diamonds have the same carat weight and qualities, you can expect the cushion cut diamond to cost anywhere from 25% to 50% less.

Oval, pear and marquise diamonds have a larger surface area, while princess and asscher cut diamonds are smaller, with just around 5.5mm table size. While this may seem small, a 1 carat diamond is absolutely big enough to draw attention.

Cushion cuts also ‘face up’ smaller than some other shapes of diamond, which means that they look slightly smaller when viewed from the top. This is because as they are cut deeper carry more of their weight under the ‘girdle’ of the stone ie.

The stone is said to be an H in colour, VVS in clarity and certified by the GIA. Experts have estimated the cost of Tiffany’s ring to be US$1-$1.2 million, but Fergus James, a British private jeweller based in Dubai, disagrees.
