Choosing a Marquise Diamond: Factors to Consider
When it comes to choosing a diamond that exudes elegance and sophistication, the marquise cut is unparalleled. Its distinct shape maximises carat weight, giving the illusion of a larger stone. This guide is designed to help you understand the key factors to consider when selecting a marquise diamond, ensuring your choice is nothing short of perfect.
The Best Ratio for a Marquise Cut
DiamondThe aspect ratio (length-to-width ratio) plays a pivotal role in the overall look of a marquise diamond. It's what determines the stone's profile - from slender and elongated to shorter and wider. The ideal ratio for a marquise diamond is considered to be between 1.85 to 2.10. This range ensures that the diamond’s proportions are perfectly balanced, offering the most pleasing aesthetic. However, the choice can vary based on personal preference and how the diamond complements the wearer's hand.
Marquise Cut Guide
The quality of the cut is paramount in showcasing the diamond's brilliance and sparkle. A well-cut marquise diamond will have symmetrical points and sides, ensuring that the light is reflected evenly throughout the stone. When examining a marquise diamond, pay close attention to the alignment of its facets and ensure that they are perfectly proportioned.
Marquise Colour Guide
Colour is another crucial factor to consider. Marquise diamonds, due to their shape, can sometimes show colour more readily than other cuts, particularly at the points. Diamonds are graded from D (colourless) through to Z (light colour). For marquise diamonds, a colour grade of H or higher is recommended to ensure that any visible tint does not distract from the stone’s radiant sparkle.

History of Marquise Cut
The marquise cut diamond, also known as the "navette" shape, is reminiscent of a boat (navette being French for "little ship") and features an elongated body with pointed ends. This cut maximises carat weight, giving the illusion of a larger, more opulent diamond. Its history purportedly dates back to the French royal court, when King Louis XV commissioned a diamond to reflect the smile of his beloved Marquise de Pompadour.
