Why choose a marquise?
A marquise is a long, boat-shaped cut with two points. It has the longest outline for its weight of the shapes we offer, so it looks the biggest face-up per carat, with a vintage feel.
Every marquise center here is lab-grown and comes with an IGI grading report that lists its exact measurements. Pick the carat, gold color and karat above; the price on each design updates as you go.

Questions
Does a marquise look bigger than a round of the same carat?
At 2 ct a marquise is about 12.9 × 6.6 mm face-up; a 2 ct round is about 8.1 mm across. Exact measurements are on your stone's IGI report.
Is a lab-grown marquise a diamond?
Yes. A lab-grown diamond is diamond, the same material as a mined diamond, grown in a controlled environment instead of mined. Every center stone here is lab-grown and comes with an IGI grading report.
What carat sizes can I choose?
Choose the carat on each ring page; the options vary by design. Want a bigger stone? Call or text 321-521-4651 and we will quote it.
How long does my ring take?
Each ring is made to order after you choose the carat, quality and metal. Plan on about 3 weeks; the ring page shows the estimated ship-by date for today's order.
