Emerald Cut Ratio Calculator

Emerald cut diamonds are admired for their elegant, rectangular shape, and the length-to-width ratio is a key factor in determining their overall appearance. A well-balanced ratio contributes to the classic, sophisticated look of the emerald cut.

Historical Background

The emerald cut was originally developed for cutting emeralds, which are delicate and prone to chipping. Over time, the style became popular for diamonds, giving the stones a sleek, elongated look that highlights their clarity and luster.

Calculation Formula

The length-to-width ratio is calculated as:

\[ \text{Length-to-Width Ratio} = \frac{\text{Length (mm)}}{\text{Width (mm)}} \]

Ideal Ratio

• 1.30 - 1.40: Traditional and elegant; most common for emerald cuts.
• 1.40 - 1.50: Slightly longer, offers a more modern and elongated look.
• 1.50+: Very elongated, unique appearance.

Example Calculation

If an emerald cut diamond has a length of 8.0 mm and a width of 5.5 mm, the length-to-width ratio would be:

\[ \text{Length-to-Width Ratio} = \frac{8.0}{5.5} \approx 1.45 \]

Importance and Usage Scenarios

The length-to-width ratio affects the visual appeal and style of an emerald cut diamond. Jewelers and buyers often consider this ratio when selecting stones to ensure they meet personal aesthetic preferences.
