Dutch Marquise Lab-Grown Diamonds
The Dutch Marquise Cut Diamond features an elongated silhouette with softened points, offering a refined twist on a timeless shape.
What is a Dutch Marquise diamond?
A Dutch Marquise is an elongated, boat-shaped diamond in the marquise (navette) family, distinguished by its gently softened points — a refined twist on the classic marquise's sharp tips. The result is a long, graceful silhouette with a vintage sensibility that still reads bright and modern, with sparkle spread across a generous surface area.
Dutch Marquise vs. the classic marquise
A traditional marquise tapers to two sharp points. The Dutch Marquise keeps the elongated navette outline but softens those points — giving it a gentler, more antique-inspired look and making the delicate tips far less vulnerable to chipping. If you love the slimming, elongating effect of a marquise but want something a little less severe, the Dutch Marquise is the answer.
What to look for in a Dutch Marquise
- Length-to-width ratio — most look best between about 1.85 and 2.10; lower reads broader, higher reads slimmer. Choose by taste.
- Point symmetry — the two ends should align so the stone doesn't look crooked once set.
- Bow-tie — like all elongated cuts, a faint dark band can appear across the centre; look for one that's minimal.

Dutch Marquise engagement rings
The elongated shape flatters the finger and looks larger per carat than rounder cuts, which makes the Dutch Marquise a striking centre stone. It pairs beautifully with a slim solitaire band, a delicate halo, or an east-west setting. Pick your loose stone here, or explore our Dutch Marquise engagement rings.
