How to buy a emerald cut diamond
- •Invest in clarity: VS2 is the minimum recommended grade; VS1 or VVS2 is safer due to the open table
- •Color is very visible. Stay at G or higher in white gold or platinum. I or J can work in yellow gold.
- •Check the corners: well-cut emerald cuts have beveled corners, not sharp 90-degree angles
- •Look for even, parallel step facets without a 'windowed' or washed-out center
- •The ideal depth percentage is 60-68%; stones outside this range may leak light
- •L/W ratios of 1.40-1.50 are most versatile, but personal preference varies
- •Consider this shape if your priority is clean elegance over maximum sparkle

Frequently asked questions
Is an emerald cut diamond a good choice?
Yes, for buyers who prefer clean, architectural elegance over maximum sparkle. Emerald cuts offer a distinctive hall-of-mirrors effect and cost 30 to 40% less per carat than rounds. You will need higher clarity (VS2 or above) and color (G or above in white metals) because the open table reveals imperfections that brilliant cuts hide.
How big is a 1-carat emerald cut diamond?
A 1-carat emerald cut measures approximately 6.9 x 5.0 mm. The shallow depth and elongated outline give emerald cuts a large face-up appearance relative to their carat weight.
How much does an emerald cut diamond cost?
Emerald cuts are among the most affordable shapes per carat, typically running 30 to 40% below equivalent round brilliants. The savings from the shape should be partially reinvested in higher clarity and color grades to keep the stone looking clean.
What is the best setting for an emerald cut diamond?
A solitaire is the most popular choice, letting the clean step-cut lines speak for themselves. Three-stone settings with trapezoid or baguette side stones create a classic Art Deco look, and a bezel protects the vulnerable corners while enhancing the geometric aesthetic.
Does an emerald cut diamond show inclusions more?
Yes. The large, open table acts like a window into the stone, making inclusions and body color far more visible than in brilliant cuts. Most trade professionals recommend VS2 clarity or higher, and stones graded SI1 or lower will almost certainly show visible inclusions to the naked eye.
