Emerald Cut
Also called step cut, octagon cut
Emerald cut is a rectangular diamond cut with cropped corners and long parallel facets arranged in steps. It produces broad flashes of light rather than fine sparkle, and its open table shows the inside of the stone clearly.
Why it looks different
Step cuts do not chop light into small flashes the way a brilliant does. The long facets act more like mirrors, giving the hall of mirrors effect people describe, with slower and wider flashes as the stone moves.
That open look has a cost. Because the table is large and unbroken, inclusions and body colour show more readily than they would in a round of the same grades. Buyers of emerald cuts tend to shop a grade higher on clarity.
What the render has to show
An emerald cut render lives or dies on the step facets. If the steps are not parallel and evenly spaced, the mirror effect breaks and the stone reads as flat glass.
We keep the stone slightly under filled with light rather than blasting it, because an over lit emerald cut loses the dark and light banding that makes the shape recognisable. The turntable video is where this shape sells itself.
Questions about Emerald Cut
Why do emerald cuts show inclusions more?
The large open table gives a clear view straight into the stone, with no small facets to break up what you see. Higher clarity grades are worth more on this shape.
Is an emerald cut less sparkly?
It sparkles differently. You get fewer, broader flashes instead of the fine scatter a round brilliant gives.
