Elongated Hexagon Lab-Grown Diamonds
A modern six-sided geometric cut with clean lines — architectural, elongated, and distinctly contemporary.
What is an elongated hexagon diamond?
An elongated hexagon is a six-sided geometric cut stretched lengthwise, with clean straight edges and angled corners. It has a modern, architectural feel — geometric and distinctive rather than traditional — and reads beautifully both set north-south and east-west.
The look: geometric and modern
Hexagon cuts are usually faceted in a step or mixed style, giving clean, mirror-like flashes rather than the busy sparkle of a brilliant. The elongated proportions slim and lengthen the finger, and the geometry makes the stone feel contemporary — a favourite for shoppers who want something off the beaten path.
What to look for in an elongated hexagon
- Ratio — choose how elongated you want it; longer hexagons look slimmer and more dramatic.
- Symmetry — the six sides and corners should be even so the geometry looks crisp.
- Clarity — open, step-style facets show inclusions more, so lean toward cleaner VS grades.
