Emerald Cut Lab Grown Diamonds
A step-cut diamond with long, clean lines and a dramatic "hall of mirrors" — understated, elegant, and elongating.
What is an emerald cut diamond?
The emerald cut is a step cut — a rectangular shape with an open table and long, parallel facets running down its length. Instead of the fiery sparkle of a brilliant, it produces broad, mirror-like flashes of light known as the "hall of mirrors." The effect is understated, architectural, and elegant, and the elongated outline flatters the finger.
Why clarity matters most for emerald cuts
Because the emerald cut's facets are large and open, they act like clear windows into the stone — so inclusions are easier to spot than in a sparkly brilliant. For an eye-clean look, prioritise clarity (VS and up performs beautifully) and a fairly even colour. It's the one shape where clarity earns its place at the top of your list.
What to look for in an emerald cut
- Ratio — a classic emerald sits around 1.30–1.50; go higher for a longer, more dramatic stone.
- Clarity — aim eye-clean (VS or better) since the open facets reveal more.
- Even step facets — crisp, parallel lines are the hallmark of a well-cut emerald.

Emerald cut engagement rings
The clean lines suit solitaire, three-stone, and east-west settings, and read as quietly sophisticated rather than flashy. The elongated shape also looks larger per carat than a round. Choose your loose stone here, then build it into the ring of your choice.

Emerald Cut Lab Grown Diamonds — frequently asked questions
What is an emerald cut diamond?
A rectangular step cut with an open table and long parallel facets, giving broad 'hall of mirrors' flashes rather than fiery sparkle — understated and elegant.
Why doesn't an emerald cut sparkle like a round?
It's a step cut, not a brilliant cut. Its large, open facets produce mirror-like flashes of light instead of the small, fiery sparkle of a round.
What clarity should I choose for an emerald cut?
Aim eye-clean — VS or better. The open step facets reveal inclusions more than a sparkly brilliant, so clarity matters most here.
What length-to-width ratio is best for an emerald cut?
A classic emerald sits around 1.30–1.50. Go higher for a longer, more dramatic 'elongated emerald' look.
Are emerald cut lab grown diamonds real diamonds?
Yes — they're real diamonds, chemically and optically identical to mined stones, and recognized as diamonds by the FTC.
Are emerald cut lab grown diamonds certified?
