And here’s our quick need-to-know on each one in order of popularity - with a rough estimate for the cost of a 1 carat , H color , VS1 clarity diamond by shape.
Round Brilliant Cut Diamonds
If you’re scared of going wrong, this is definitely a safe choice. Classic, traditional, and the most popular one by far. However, you could get the same size (carat weight) in a non-round for less.

Cushion Cut Diamonds
So this is definitely ‘in’ right now. Meghan Markle, Priyanka Chopra all got cushion diamonds in their engagement ring. It kind of looks like a round from far away, it’s still a classic shape, and is cheaper than the round for the same size.
