Dutch Marquise Lab-Grown Diamonds

Q: How do I evaluate the quality of a Dutch Marquise diamond?

Evaluate Dutch Marquise diamonds by checking the 4 Cs: cut, clarity, color, and carat weight. Look for excellent or very good cut for maximum brilliance, VS2 clarity or higher, and color grades D–F for icy brilliance or G–H for warmer tones. Certification from GIA, IGI, or GCAL ensures verified quality and traceability.

How Dutch Marquise Lab-Grown Diamonds Are Created

These diamonds are created using advanced growth methods such as High Pressure High Temperature (HPHT) and Chemical Vapor Deposition (CVD). For elongated shapes like the Dutch Marquise, precision during both growth and cutting is essential to maintain symmetry, balanced proportions, and consistent light performance across the extended silhouette.

After formation, each diamond is expertly cut into the Dutch Marquise shape, with careful attention to facet alignment and proportions to enhance brilliance, fire, and overall visual performance.
