Marquise Cut Lab Grown Diamond Engagement Rings

Marquise cut lab grown diamond engagement rings combine an elongated silhouette with graceful curves and pointed ends. Their distinctive shape creates an elegant presence on the hand, making them a beautiful choice for anyone drawn to a ring with character and a sense of individuality.

The marquise cut offers a generous face up appearance relative to its carat weight. Its long outline can create the impression of a longer finger, while brilliant faceting brings sparkle across the stone. Some marquise diamonds appear slender and dramatic, while others have a wider, softer profile.

Lab grown diamonds are real diamonds, with essentially the same chemical composition, crystal structure and physical properties as natural diamonds. Created in a controlled environment, they offer greater flexibility when balancing diamond size, quality and your preferred setting within your budget.

A solitaire highlights the marquise diamond’s distinctive outline, while a pavé band adds delicate sparkle. An east west setting places the diamond horizontally for a different look, and complementary side stones can create a more detailed design.

When selecting a marquise diamond, look for balanced curves, symmetrical tips and appealing brightness. View it in motion to assess any dark bow tie pattern across the center. A thoughtfully designed setting should also help protect both pointed ends.

Yellow gold brings warmth, white gold offers a crisp finish, and rose gold adds a softer touch.
