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
