The octagonal shape lab diamond has eight straight sides, usually four longer sides that switch off with four shorter corners cut on an angle. That corner trim softens a shape that would be a plain rectangle without it, giving the stone a neat, tailored look. Because those eight sides need to stay even, cutting this shape takes careful, patient work. That care adds a little to the price.
This lab grown diamond is most often finished in the step-cut style, with broad, flat facets running in from each edge instead of many small ones. That kind of facet layout throws back a steady, open glow instead of the quick flicker of a brilliant cut, and it also lets the stone’s own color come through clearly. Cut well, a stone like this holds that same steady flash from edge to edge.
An octagonal lab diamond stays fixed as the shape here, so carat weight, color, clarity, and how well the stone is cut set the price of this lab created diamond. Small marks show up a bit more here than with a brilliant cut, since the open facets make them easier to see. Color and carat weight fill in most of what remains.
This cut works well as a center stone in a simple solitaire, letting its clean, even outline hold the full focus. It also suits a three-stone ring, flanked by two smaller round or baguette stones on either side. Some buyers choose this shape for a men’s ring, since its trimmed corners give it a sturdier look. A few customers also like to set this shape into a plain wedding band.
This lab grown diamond gives buyers a shape close to the well-known Emerald and Asscher cuts, but with its own distinct, many-sided outline. It suits anyone who wants that same calm, open sparkle without picking the exact shape everyone else chooses. That mix of familiar style and a fresh outline keeps this cut in steady demand.

The two shapes share the same step-cut style and open, calm flash. The real difference is the outline: this shape has eight sides instead of four, giving it a more rounded, many-sided look next to a plain rectangle.
Yes, somewhat, since the open, flat facets on this shape make small marks a little easier to see than a round brilliant cut would hide, mostly under bright, direct light. A clear stone keeps that clean, glassy look sharp, so buyers often pick a slightly higher clarity grade for this shape.
Yes, it is a popular pick for a men’s ring, since its trimmed corners and clean lines give it a sturdier look compared to a rounder shape, and that same shape holds up well against daily wear. It also pairs well with a wide, plain band for a clean, bold look that still feels quiet rather than flashy.
