The Ultimate Guide to Choosing a Marquise Diamond

When it comes to selecting a diamond that exudes elegance and timeless charm, the marquise diamond stands out as a distinctive choice. Its unique shape, historical roots, and brilliant sparkle make it a favourite for those seeking something extraordinary. If you’re considering a marquise diamond, here’s everything you need to know to make the perfect choice.

What is a Marquise Diamond?

The marquise diamond, also known as the "navette" (meaning "little ship" in French), features an elongated shape with pointed ends and a curved centre, resembling a boat or an eye. This cut dates back to the 18th century when King Louis XV of France commissioned a diamond to mimic the shape of his mistress’s lips, the Marquise de Pompadour.

Key Features to Consider

1. Shape and Symmetry: A well-cut marquise diamond should have perfectly symmetrical sides. The two pointed ends must align, and the curves should be smooth and even to maintain balance and aesthetic appeal.
2. Length-to-Width Ratio: This ratio significantly influences the diamond’s appearance. A common preference is between 1.75 to 2.25, offering an elegant, elongated look. A lower ratio gives a wider, more robust shape, while a higher ratio results in a slimmer, sleeker design.
3. The Bow-Tie Effect: Marquise diamonds often display a bow-tie-shaped shadow across the centre. While some bow-tie presence is inevitable, the goal is to minimize it for maximum brilliance. Inspect the diamond under different lighting conditions to assess this feature.
4. Carat Weight and Size Perception: The marquise cut maximizes carat weight, giving the illusion of a larger diamond compared to other shapes of the same weight. Its elongated form also creates a slimming effect on the finger, adding to its allure.
5. Color and Clarity: Due to its large surface area, color and inclusions can be more noticeable in a marquise diamond. Opt for a higher color grade (G or better) and clarity (VS2 or higher) to ensure a bright, eye-clean appearance.

Setting Styles That Complement Marquise Diamonds

• Solitaire: Showcases the diamond’s shape without distraction.
• Halo: Adds extra sparkle and can make the centre stone appear larger.
• East-West Setting: A modern twist that places the diamond horizontally.
• Vintage Settings: Emphasizes the antique charm with intricate details.

What Makes Marquise Diamond a Good Choice for Engagement Rings?

• Unique, eye-catching shape
• Larger appearance for its carat weight
• Elegant, elongating effect on the finger

Tips for Buying a Marquise Diamond

1. Inspect in Person: Whenever possible, view the diamond in different lighting to evaluate brilliance and symmetry.
2. Prioritize Cut Quality: More than any other factor, a well-cut marquise diamond will enhance sparkle and minimize flaws.
3. Consider a Protective Setting: To safeguard the pointed tips, choose settings with prongs or bezels.

Choosing a marquise diamond is about embracing individuality and timeless elegance. Its regal history, distinctive silhouette, and brilliant sparkle make it a standout choice for engagement rings and fine jewellery. By focusing on key factors like symmetry, cut quality, and setting style, you can find a marquise diamond that perfectly reflects your unique taste and style.
