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.
