Ratio
The ratio of a diamond, especially relevant for fancy-shaped diamonds, refers to the proportion between the length and width of the stone. This measurement significantly influences the diamond’s overall appearance, making it a critical factor in selecting a diamond that meets your aesthetic preferences. Understanding how to navigate the ratio range will help you choose a diamond with the ideal proportions for its shape, ensuring it complements the intended setting and achieves the desired visual effect.
A diamond’s ratio is calculated by dividing its length by its width. This ratio determines the diamond’s outline or silhouette, affecting how elongated, rounded, or squared the diamond appears. Ratios are typically presented as a range (e.g., 1.00 to 1.05 for nearly square shapes or 1.30 to 1.50 for more elongated shapes), allowing buyers to understand the variation within specific diamond cuts.
Choosing the Right Ratio Range
- For Square Cuts (e.g., Princess, Asscher) : Ideal ratios are close to 1.00, indicating nearly perfect square proportions. A range slightly above 1.00 (up to 1.05) can still appear square to the naked eye, providing flexibility in selection.
- For Rectangular Cuts (e.g., Emerald, Radiant) : Preferred ratios typically fall between 1.30 and 1.50, offering a classic rectangular shape. Ratios closer to 1.30 suggest a squarer rectangle, while those closer to 1.50 or beyond emphasize a more elongated appearance.
- For Elongated Cuts (e.g., Marquise, Oval, Pear) : These shapes vary widely in ideal ratios. For example, ovals and pears may range from 1.40 to 1.70, and marquise cuts often fall between 1.85 to 2.10, depending on the desired length-to-width appearance.
Pear : Gemayel recommended ratio : 1.45 to 1.7
Princess : Gemayel recommended ratio: 1 to 1.04
Emerald: Gemayel recommended ratio: 1.35 to 1.55
Asscher : Gemayel recommended ratio: 1 to 1.05
Marquise : Gemayel’s recommended ratio: 1.75 to 2.1
Oval : Gemayel’s recommended ratio: 1.38 to 1.6
Radiant : Gemayel’s recommended ratio: 1.15 to 1.35
Heart : Gemayel’s recommended ratio: 0.85 to 1.1
Cushion : Gemayel’s recommended ratio: 1.15 to 1.3
- Perceived Size : Elongated ratios can make a diamond appear larger on the finger, a desirable trait for many buyers seeking impressive visual impact.
- Visual Balance : The right ratio ensures that the diamond is proportionally balanced, enhancing its beauty and symmetry.
- Style Match : The ratio can also complement personal style and the setting’s design, making the diamond’s shape more pronounced or subtle based on individual preferences.
- Consider Personal Preference : Determine whether you prefer a more classic or distinctive look. Some may favor the uniqueness of an elongated cut, while others might opt for the balanced symmetry of a square or slightly rectangular shape.
