1. What Is an Emerald Cut Diamond?
The emerald cut is one of the oldest diamond shapes, originally developed for cutting emeralds (hence the name) and later adapted for diamonds due to its elegance and precision.
Key Features:
-
Step cuts: Long, narrow facets arranged parallel to the girdle.
-
Rectangular shape: Typically features a length-to-width ratio between 1.30 and 1.50.
-
Open table: The top surface of the diamond is broad and transparent.
-
Chic corners: Trimmed edges give it a sophisticated, Art Deco appearance.
Emerald cut diamonds emphasize clarity over sparkle, offering a “hall of mirrors” effect with dramatic flashes of light rather than intense brilliance.
2. History of the Emerald Cut
The emerald cut dates back to the 16th century, initially used for emerald gemstones. Jewelers found that the step cut reduced pressure during the cutting process, minimizing the risk of chipping. Over time, this cut gained popularity for diamonds during the Art Deco era in the 1920s and 1930s, when geometric lines and symmetry defined fashion and design.
Today, emerald cut diamonds remain a favorite for those seeking vintage glamour, minimalist beauty, and architectural elegance.
3. Why Choose Loose Emerald Cut Diamonds?
Purchasing a loose emerald cut diamond offers distinct advantages over buying pre-set jewelry.
a. Customization
Loose stones give you the freedom to:
-
Choose your own setting
-
Match with complementary stones
-
Design one-of-a-kind jewelry pieces
b. Better Value
When you buy a loose diamond, you can clearly assess the 4Cs (Cut, Clarity, Color, Carat) and compare prices across vendors, ensuring transparency and cost-effectiveness.
c. Investment Flexibility
Loose diamonds can be stored securely, resold more easily, or passed down as family heirlooms.
4. The 4Cs of Emerald Cut Diamonds
Understanding the 4Cs is essential when evaluating any diamond, especially emerald cuts which highlight certain features more prominently.
a. Cut
Unlike round diamonds, emerald cuts do not have a traditional cut grade from GIA. However, factors like:
-
Symmetry
-
Polish
-
Facet alignment
affect the visual appeal significantly. A well-cut emerald diamond should have sharp step facets and balanced proportions.
b. Clarity
Because of the large, open table, inclusions and blemishes are more visible in emerald cut diamonds. It’s advisable to choose:
-
VS1 or higher for eye-clean appearance.
-
Internally Flawless (IF) for high-end purchases.
c. Color
Emerald cuts show more color than other shapes due to their open facets. Color grades D–G are preferred for those who want a bright, icy appearance, while H–J may still appear white in yellow or rose gold settings.
d. Carat Weight
Emerald cut diamonds appear larger than round diamonds of the same carat due to their surface area. They provide excellent face-up size, making them a cost-effective way to maximize visual impact.
5. Ideal Emerald Cut Proportions
While preferences vary, the following parameters are generally considered ideal:
| Feature | Ideal Range |
|---|---|
| Table % | 61%–69% |
| Depth % | 60%–68% |
| Length-to-Width Ratio | 1.30–1.50 |
| Girdle Thickness | Medium to Slightly Thick |
| Culet | None to Small |
Emerald cut diamonds with ideal proportions will have a strong balance between brightness, symmetry, and elegance.
6. Popular Settings for Emerald Cut Diamonds
When designing custom jewelry with loose emerald diamonds, the setting plays a critical role in the final aesthetic.

b. Halo Setting

c. Three-Stone Setting
