An 18ct gold ring in the Art Deco style, centred on a 0.76-carat emerald-cut aquamarine in a rub-over setting, framed by a surround of brilliant-cut and baguette-cut diamonds with diamond accents continuing along the shoulders. The emerald cut — a rectangular step-cut with cropped corners and long, open facets — is a particularly sympathetic choice for aquamarine. Where a brilliant cut maximises sparkle, the step-cut facets of the emerald cut emphasise the clarity and colour of the stone, allowing the pale, glacial blue of the aquamarine to be seen in its full depth rather than broken up by the movement of light across a faceted surface.

The combination of brilliant-cut and baguette diamonds in the surround gives the setting a geometric quality that is entirely in keeping with the Art Deco aesthetic — the clean lines of the baguettes framing the centre stone, the brilliant cuts adding warmth and sparkle to either side. The rub-over setting of the aquamarine, with its continuous rim of gold enclosing the stone, gives the centre a clean, uncluttered profile that suits the simplicity of the cut.
