Buying Guide: Key Considerations for Marquise Diamonds
- Find the right setting: Marquise shapes are versatile in rings, bracelets, and earrings. Choose a setting that enhances the lengthening silhouette of the stone.
- Evaluate cut and symmetry: A well-cut marquise will have balanced facets and a pronounced point; look for stones with clean outlines to maximize brilliance.
- Lab-grown vs mined: Lab-grown diamonds typically offer lower cost per carat and ethical sourcing. Consider your priorities for price versus natural provenance.
- Calibration and size: For designers, calibrated sizes ensure consistency across multiple pieces. For buyers, verify that the stone sizes fit your setting accurately.
- Color and clarity expectations: Marquise stones can show pronounced bow-tie effects if cut poorly. Prefer stones with even color shading and minimal bow-tie visibility.
- Durability: Diamond hardness supports long wear; check surrounding metal settings for secure mounting and durability in daily use.
- Certification: Consider stones or pieces with documented grading standards (GIA/IGI) when available to confirm color, clarity, and carat.

Lab-grown marquise diamonds have identical chemical composition to mined stones but are created in controlled lab environments, often offering better pricing and traceability.
