History, Types, Cultural Significance Of Marquise Cut Lab Diamond Engagement Ring
The marquise cut diamond, also known as the “navette” cut, dates back to 18th-century France and was originally commissioned to resemble the smile of a royal mistress. Today, its elongated, boat-like shape continues to charm couples who want a ring that blends tradition with individuality.
Our collection of marquise cut lab diamond engagement ring brings this romantic silhouette into the modern age. We offer designs in solid 14K & 18K gold—available in white, yellow, or rose—that range from sleek solitaires to dazzling halos and three-stone bands. Whether set vertically for a traditional look or east-west for a trendy twist, the marquise cut makes a bold and flattering statement.
