How to Choose the Best Ratio for You
Choosing the right length-to-width ratio depends on your personal taste and style. Here are some tips to help you make the best choice:
- Consider Your Finger Shape: Longer, slender fingers pair well with elongated shapes like oval or marquise. Shorter or wider fingers benefit from round or square shapes.
- Think About the Setting: The setting style can visually affect the ratio. A bezel setting can make the diamond appear smaller, while a halo setting can make it look larger.
- Personal Style: Your personal taste should ultimately guide your decision. Choose a higher ratio if you prefer an elongated look, or stick to the recommended ratios for a classic appearance.
- Try It On: If possible, try diamonds with different ratios to see how they look on your hand.
- Consult an Expert: Jewelers have a trained eye and can help you find the perfect diamond that matches your style and budget.
- Ratio Isn’t Everything: Diamond quality is influenced by other factors such as the 4Cs. However, you must also consider many things to find a truly beautiful diamond.
