✦ The Silhouette Breakdown ✦

Dutch Marquise vs. Traditional Marquise

While a traditional marquise cut features smooth, curved sides that form a boat-shaped navette outline, the Dutch Marquise replaces those rounded arcs with six straight, precision-angled geometric edges.

This structural modification solves two major challenges associated with classic marquise diamonds:

  • Reduced Bow-Tie Effect: The straight lateral facets direct light reflections more uniformly toward the viewer's eyes rather than creating a dark center bowtie band.
  • Flush Wedding Band Stacking: Because its flanks are straight rather than bowed outward, straight and contoured wedding bands sit flush against engagement settings without awkward gaps.

Frequently Asked Questions

Key guidance for purchasing certified Dutch Marquise lab grown diamonds.

A Dutch Marquise (also known in antique circles as a hexagonal or rupee cut diamond) is an elongated diamond shape that retains the pointed tips of a traditional marquise but features six straight, angular sides instead of curved arcs. This gives it an architectural, Art Deco feel with exceptional finger length.

Gemological laboratories such as the IGI and GIA typically classify certified Dutch Marquise diamonds as **"Hexagonal Modified Brilliant"** or **"Marquise Modified Brilliant"**. The report includes precise millimeter dimensions, facet arrangement diagrams, and unique laser inscription numbers.

Because the lateral facets are straight rather than curved, light reflects more evenly across the midsection of the stone. In our Surat synthesis and cutting facility, facet angles are specifically calibrated to minimize or completely eliminate the dark center bow-tie common in commercial curved marquise cuts.

Like any diamond with pointed ends, a Dutch Marquise should be secured with **V-prongs (chevron prongs)** on both tips to safeguard against accidental knocks. Six-prong settings (two V-prongs on the ends and four side prongs on the straight edges) or sleek full-bezel mountings accentuate its crisp hexagonal geometry beautifully.

Yes! One of the major advantages of the Dutch Marquise over a traditional curved marquise is that its long side walls are straight. When mounted in a raised cathedral or low-profile basket, standard straight wedding bands can sit flush against the ring without needing a custom-curved or notched gap band.
