All you need to know about Marquise Diamonds (Ratio proportions and more)

The marquise cut diamond, with its elongated silhouette, is a captivating choice for engagement rings and other fine jewelry. Its brilliance and unique shape have made it a timeless classic. A key factor in determining the overall appearance of a marquise diamond is its length-to-width ratio.

Understanding Length-Width Ratio

The length-width ratio of a marquise diamond is the comparison of its length (from point to point) to its width (at the widest part). This ratio significantly influences the diamond's overall look.

Impact of Ratio on Appearance

Marquise diamonds typically have a length-to-width ratio ranging from 1.70 to 2.20. This range offers a variety of styles:

  • Classic Marquise (1.70 to 1.80): This ratio creates a balanced and elegant look, with a subtle elongation that flatters the finger.
  • Elongated Marquise (Above 1.80): A higher ratio results in a more dramatic, slender appearance. While striking, an excessively elongated marquise may appear too narrow.
  • Rounded Marquise (Below 1.70): Less common, this ratio creates a shorter, plumper look, resembling a teardrop or navette shape.

Choosing the Right Ratio

The ideal length-width ratio depends on personal preference and finger shape. Consider these factors:

  • Desired look: Classic, elongated, or rounded?
  • Finger shape: Elongated marquises can complement shorter fingers, while rounder ones might suit longer fingers.

Beyond the Ratio

While the length-width ratio is crucial, other factors impact a marquise diamond's beauty:

  • Cut quality: A well-cut marquise maximizes brilliance and fire.
  • Clarity: Fewer inclusions enhance the diamond's clarity.
  • Color: Colorless or near-colorless diamonds are typically preferred.
