This 1.25 CT marquise lab-grown diamond ring is constructed with a single marquise-shaped lab-grown diamond secured in a prong-based ring setting. The marquise diamond features an elongated outline with pointed ends and a defined table surface, positioned centrally along the band axis to maintain balanced alignment and proportional symmetry. The stone orientation preserves consistent surface presentation when viewed from top and profile angles.
The prong setting is engineered to stabilize the diamond at measured contact points while keeping the crown and table facets unobstructed. Prong placement supports both pointed ends and the curved sides of the marquise shape without interrupting the outline or facet visibility. Open space beneath the diamond allows controlled light entry and interaction with the cut facets.
The band structure maintains a uniform width and thickness to support balanced distribution of total carat weight and stable wear. The total carat weight of 1.25 CT provides defined surface coverage while maintaining a controlled vertical profile. The ring is manufactured to ensure alignment consistency across top, side, and profile views.
All diamonds used in this ring are lab-grown and graded according to standardized parameters for color, clarity, and cut. Information on marquise shape geometry and outline behavior appears in the Diamond Shapes Guide. Guidance on diamond cut behavior and facet interaction is detailed in the Diamond Cut Quality Guide. Broader purchasing and evaluation considerations are outlined in How to Choose a Lab Grown Diamond.
