Emerald Cut Diamond: A Timeless Classic
The Emerald Cut Diamond is a step-cut diamond known for its elegant, elongated shape and hall-of-mirrors effect. It is one of the most sophisticated diamond cuts, often chosen for engagement rings and fine jewelry due to its vintage charm and unique sparkle.
Key Characteristics of an Emerald Cut Diamond
1. Shape & Faceting Style
Rectangular shape with cut corners
Step-cut faceting: Unlike the brilliant-cut diamonds that maximize sparkle, the Emerald Cut has long, parallel step-like facets (usually 57 or 58 facets).
Large, open table: The wide top surface enhances clarity, making inclusions more visible compared to round or cushion cuts.
Hall of Mirrors Effect: The parallel step-cut facets create a mesmerizing play of light and dark reflections.
2. Facet Structure
Crown (Top): Large, flat table with linear step facets.
Girdle (Middle): The widest part, providing durability.
Pavilion (Bottom): Parallel step facets that create depth and reflection.
Cut Corners: Prevent chipping and add to durability.
Emerald Cut Diamond Proportions & Ratio
Ideal Length-to-Width Ratio:
1.30 to 1.50 is the most common and elegant proportion.
Squarer Emerald Cuts (1.20-1.30) are sometimes called “Asscher Cuts” (which are more octagonal).
Depth Percentage:
Ideally between 60% and 70% to balance light reflection.
Table Percentage:
Typically 60% to 68% of the total width.
Brilliance & Sparkle
Subtle, understated sparkle: Unlike a Round Brilliant Cut, which maximizes fire and brilliance, the Emerald Cut has a softer glow, focusing more on clarity and elegance.
Less dispersion (fire): The step-cutting style does not break light into as many colorful flashes as a brilliant cut.
More clarity-dependent: Due to the large open facets, inclusions and flaws are more visible.
