Description
- ✓ Octagon emerald cut center
- ✓ Chemically and optically identical to a mined diamond
- ✓ IGI-certified lab grown diamond (1ct and above)
An octagon emerald cut takes the classic step cut and trims the corners, giving the stone an eight-sided outline with a clear Art Deco flavor. It's the shape you see in vintage rings from the 1920s and 30s, and it reads more distinctive than a standard rectangle without losing the calm, architectural look of a step cut.
Like any emerald-style cut, it hides nothing. The long open facets act as windows into the stone, so color and clarity carry the look. Every center is graded E color (colorless) and VS clarity, exactly the range where a step cut stays clean and icy rather than showing tint or inclusions. Choose1ct 2ct or 3ct depending on the spread you want.
Pick 14K or 18K yellow gold; the warm tone plays nicely against the cool white of the diamond, leaning into that vintage feel.
On the diamond: lab grown means it was created in a controlled facility rather than mined. It's the same carbon crystal, the same hardness and fire. A real diamond, in a shape with real history.
