3 Carat Marquise Cut Green Lab Grown Diamonds

A 3 carat green marquise has a lush, nature-inspired presence across a dramatic elongated silhouette. The green fills the boat-shaped body with rich, emerald-rivaling sparkle. At 3 carats, the marquise's face-up advantage makes the green appear even larger than its weight.

A dramatic alternative. The marquise shape is entirely different from the traditional emerald cut, creating a sweeping green presence with more sparkle and maximum face-up size. At 3 carats, it's for buyers who want green color in the most dramatic, elongated silhouette possible.

The marquise cut's dramatic elongated shape with pointed ends that maximizes perceived size gives it strong finger presence. The green hue is exceptionally rare in nature, available through lab creation, adding collectible appeal. 3 carat marquise lab diamonds are about a carat above the average lab diamond size in the USA and are a wonderful place to maximize beauty, size, and value.
