Real diamonds, real prices

Every ring on this page pairs a specific marquise diamond from our natural or lab grown inventory with one of our settings. The price you see is the finished ring: setting plus that exact diamond. We refresh the stones every day, so a diamond that sells is replaced the next morning.

Tap a ring to change the metal or ring size, see the diamond's details, or swap in another stone.

Natural or lab grown

  • Natural: mined diamonds, each with a GIA report. Rarer and higher in price.
  • Lab grown: the same material as a mined diamond, grown in a lab, each with an IGI report. A 1 carat marquise costs a fraction of a natural one.
  • Lab grown rings carry a Lab grown label, and the switch above the rings shows one kind or both.

What to look for in a marquise diamond

  • Length to width: most marquise diamonds fall between 1.75 and 2.25. Longer stones look slimmer on the finger.
  • Bow tie: a dark band across the middle, common in marquise cuts. Look at the stone's photo before you choose.
  • The two points: a setting with V-shaped prongs at each tip protects them from chips.

A 1 carat marquise looks larger than a 1 carat round diamond because of its long shape.

What a marquise diamond ring costs

The price is the setting plus the diamond. With a natural 1 carat marquise, most rings here land between about $4,000 and $7,500. With a lab grown one, between about $1,250 and $4,700. Each ring's Transparency Manifest breaks the price into metal, diamond, labor, logistics and our protocol fee.

Marquise diamond rings FAQs

Are these real diamonds I can buy?

Yes. Every ring shows one specific diamond from our inventory, with its own grading report. If a diamond sells before you check out, we tell you right away and show similar stones.

Should I choose a natural or lab grown marquise diamond?

Both are real diamond. Natural diamonds are mined and rarer; lab grown diamonds look the same and cost far less. Each card shows which kind it is.

Does a marquise diamond look bigger?

Yes. Its long shape spreads the weight across more surface, so a 1 carat marquise looks larger than a 1 carat round diamond.

Can I change the metal or the diamond?

Yes. Open any ring to choose white, yellow, rose or blackened gold or platinum, set your ring size, or pick a different marquise diamond.

How much does a marquise diamond ring cost?

With a natural 1 carat marquise, most rings here cost about $4,000 to $7,500; with a lab grown one, about $1,250 to $4,700. Each ring's Transparency Manifest shows where the money goes.
