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.

  • 1ct. Natural Round H VS1 starting at: $6,200

  • 1ct. Lab Grown Round H VS1 starting at: $1400

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.

  • 1ct. Natural Cushion H VS1 starting at: $3,400

  • 1ct. Lab Grown Cushion H VS1 starting at: $1,300

Oval Cut Diamonds

Think round but just a little stretched – and it’ll make her fingers look longer and more elegant.

  • 1ct. Natural Oval H VS1 starting at: $4,675

  • 1ct. Lab Grown Oval H VS1 starting at: $1,200

Princess Cut Diamonds

You have softer, rounder shapes like above – and more angular ones like this the princess cut. It comes with a different set of things to watch out for like symmetry and ‘chevrons’.

  • 1ct. Natural Princess H VS1 starting at: $4,150

  • 1ct. Lab Grown Princess H VS1 starting at: $1,500

Emerald Cut Diamonds

This Great Gatsby look shines in a totally different way – it’s more like a ‘hall of mirrors’ than your traditional sparkle. Beyoncé rocks a massive one that’s worth $5m, for what that’s worth.

  • 1ct. Natural Emerald H VS1 starting at: $4,150

  • 1ct. Lab Grown Emerald H VS1 starting at: $1,100

Radiant Cut Diamonds

Well, it’s like a princess cut and an emerald cut got together, and you know, had a baby.

  • 1ct. Natural Radiant H VS1 starting at: $3,850

  • 1ct. Lab Grown Radiant H VS1 starting at: $1,200

Pear Cut Diamonds

You’ve got wide ones, thin ones – and the rule to follow is the Goldilocks principle: find one that’s ‘just’ right in terms of length/width ratio. 1ct. Natural Pear H VS1 starting at: $5,100 1ct. Lab Grown Pear H VS1 starting at: $1,150

  • 1ct. Natural Pear H VS1 starting at: $5,100

  • 1ct. Lab Grown Pear H VS1 starting at: $1,150

Asscher Cut Diamonds

Totally like the Emerald’s younger sibling – just with cut corners so it’s like an octagon rather than a rectangle – again, very Great Gatsby.

  • 1ct. Natural Asscher H VS1 starting at: $4,000

  • 1ct. Lab Grown Asscher H VS1 starting at: $1,300

Marquise Cut Diamonds

OK, not the most popular but it is one of my favorites. You just need to be careful on getting the right one – watch out for the length/width ratio and ‘bowties’.

  • 1ct. Natural Marquise H VS1 starting at: $4,500

  • 1ct. Lab Grown Marquise H VS1 starting at: $1,550

Heart Cut Diamonds

Like all matters of the heart, this is a tricky one. It’s an awkward shape to get right when cutting but if you like the symbolism for it, go ahead.

  • 1ct. Natural Heart H VS1 starting at: $3,575

  • 1ct. Lab Grown Heart H VS1 starting at: $2,000
