Rectangular step cuts known as emerald cut lab-grown diamonds are valued for their luxurious, subtle clarity and greater appearance per carat. IGI certified and 50% off, they display inclusions, therefore purchase colors G or higher and VS2 or better. They give long flashes rather than sparkle.

What Is an Emerald Cut Diamond?

The majority of diamonds are brilliant cuts, with thousands of tiny triangular facets oriented to reflect light within the stone and return it as brilliance.

An emerald cut diamond produced in a lab is a step cut. Its facets are long, flat and parallel, arranged in rows like steps descending to the base. Fewer facets, larger surfaces, light behaving very differently.

The outline is rectangular with clipped corners, and the flat top is unusually wide. You look straight into a lab grown emerald cut diamond rather than at a scattered surface.

What Clarity to Choose for an Emerald Cut

Buy VS2 or higher. This is the one shape where clarity genuinely matters. That open table is a window. There's no busy faceting to break up the view, so an inclusion that would vanish inside a round sits there in plain sight. Practical guidance:

  • VS2 and above, reliably eye-clean in a lab created emerald cut diamond
  • SI1, possible, but inspect the video closely first
  • SI2 and below, not worth the risk in this shape

The same logic applies to color. Step cuts show body tint more readily, so G or better in white metal. Warmer stones look fine in yellow gold.

Do Emerald Cuts Sparkle Less?

They sparkle differently, but not less, and rest depends on the design decision. A round scatters light into fine constant glitter. Lab grown emerald cut diamonds return it in broad, slow flashes, the hall-of-mirrors effect. Move your hand and distinct planes of light appear and vanish.

Nobody buys this shape for maximum brilliance. They buy it because it looks composed.

Do Emerald Cuts Look Bigger Per Carat?

Yes, for two reasons.

A lab grown emerald cut diamond has a larger table than any other shape, so more of the stone faces upward. The outline is also elongated, covering more fingers than a square or round of equal weight.

A 1ct emerald roughly measures 7.0 × 5.0mm, while a round of the same weight measures 6.5mm. On the hand it reads noticeably longer. The trade-off is depth: emerald cuts carry less of it, which is what frees up the spread.

Best Settings for an Emerald Cut

  • Solitaire, nothing interrupting those clean lines
  • Three stone with tapered baguettes, the classic Art Deco arrangement
  • Halo, adds the sparkle a step cut lacks on its own
  • Bezel, geometry against geometry, very modern
  • East-west, this turned sideways, and increasingly common

Four prongs at the cut corners is standard. Those clipped corners are structurally sound, which is why lab grown emerald cut diamonds are tougher than their delicate look suggests.

Frequently Asked Questions

What clarity should I choose for an emerald cut?

VS2 or higher. The open table acts as a window, so inclusions that hide in a round are visible here.

Do emerald cut diamonds sparkle less?

They give large planes of light instead of fine sparkles, and they flash instead of glitter. That's not a problem, it's the design functioning as planned.

Do emerald cuts look bigger than other shaped diamonds?

Yes, if you observe minutely. A 1ct emerald measures around 7.0 × 5.0mm against a round's 6.5mm. Wider table, longer outline, more presence per carat.

Can emerald cut diamonds be lab grown?

Yes, and widely available. Every emerald cut lab grown diamond we stock is IGI or GIA certified.

Are emerald cut diamonds fragile?

No. The corners are clipped rather than pointed, which makes them sturdier than pear or marquise cuts.

Why do emerald cuts cost less than rounds?

Less rough is lost cutting a rectangle than a circle. You pay for waste, and a step cut wastes far less.
