Marquise Lab Grown Diamond
Engagement Rings


The marquise cut, historically known as the navette shape, delivers a striking regal elongation with an unmatched capacity to maximize surface area and make the finger appear slender.

Defined by its pointed ends and curved middle, this elegant silhouette creates a dramatic sparkle with immense presence. Opting for a lab grown marquise cut pairs this historic, aristocratic geometry with a conflict-free origin.

At Trusamra, every marquise cut lab grown diamond ring is handcrafted in solid 14K or 18K gold. You can select white, yellow, or rose gold bands to frame the stone to your exact aesthetic.

Our lab grown diamonds are physically, chemically, and optically identical to mined diamonds. They are carefully grown in an engineered environment, completely avoiding environmental destruction and mining.

Because the sharp tips of a marquise cut are delicate, our rings feature specialized protective V-prongs or secure multi-prong mounts. Each piece is made to order in 1ct, 2ct, and 3ct sizes, complete with a physical IGI grading report and free, fully insured US shipping.
