Girdle %
The girdle percentage of a diamond, representing the girdle’s thickness relative to the diamond’s average diameter, is a crucial factor in assessing a diamond’s cut quality and durability. This guide will help you understand how to navigate the girdle percentage range when selecting a diamond from the Gemayel selection service, ensuring it aligns with your requirements for aesthetics and stability.
The girdle percentage is calculated by dividing the girdle thickness by the diamond’s average diameter, then multiplying by 100. This measurement is crucial for evaluating how the girdle contributes to the diamond’s overall proportions and how it might influence the stone’s setting and longevity. Girdle percentages are typically provided as a range (e.g., 3% to 4%), indicating the minimum and maximum thickness across different points of the girdle.
Selecting a Girdle Percentage Range
- Thin to Medium Range : A girdle percentage in the thin to medium range (about 2% to 3.5%) is often considered ideal for most diamonds, offering a balance between protection of the diamond’s edge and maintaining optimal light performance.
- Slightly Thick to Thick Range : A slightly thick to thick girdle (approximately 3.5% to 4.5%) can provide additional protection against chipping, especially in settings where the diamond’s edges are more exposed. However, excessively thick girdles may affect the diamond’s proportionality and potentially reduce its visual size.
- Very Thin to Very Thick Range : Girdle percentages that fall into the very thin (less than 2%) or very thick (greater than 4.5%) categories can pose challenges. Very thin girdles risk chipping, while very thick girdles might carry excess weight, affecting the diamond’s balance and perceived size.
- Diamond Shape : Certain shapes, like marquise, pear, or princess cuts, may benefit from a slightly thicker girdle at points prone to chipping. Round brilliants and other shapes might be more forgiving with a range of girdle thicknesses.
- Setting Style : The choice of setting can influence the preferable girdle percentage. Bezel settings, which encase the diamond’s perimeter, can protect thinner girdles.
- Aesthetic Preferences : While the girdle percentage plays a subtle role in a diamond’s appearance, personal preference regarding the diamond’s profile and how it sits in a particular setting might guide your selection.
