Marquise Cut Lab Grown Diamonds

A marquise cut lab grown diamond is an elongated shape with pointed ends on both sides, resembling a boat or an eye. With 56 to 58 brilliant-cut facets, it delivers excellent sparkle while its length creates a dramatic, eye-catching profile on the finger. The marquise has the largest face-up surface area of any diamond shape per carat weight, making it the top choice for maximizing how large your diamond appears.

Marquise cut lab diamonds appear significantly larger than other shapes at the same carat weight. Their elongated shape can look up to 15% to 20% larger face-up than a round diamond of identical carat weight. A 1 carat marquise can visually rival a 1.25 to 1.30 carat round in perceived size. This makes the marquise one of the best value-for-size choices in lab grown diamonds.

Look for a length-to-width ratio between 1.75 and 2.25 for the most classic marquise proportions. Check for a minimal bowtie effect (a dark shadow across the center) by viewing the stone face-up. Symmetry is critical: both pointed ends should align perfectly and the two curved sides should match. A V-prong setting is recommended to protect the pointed tips from chipping.
