Adjustable Four-Prong Gemstone Ring

One stone, four clean prongs, a band that sits slim against the finger. The setting stays geometric and uncluttered so the colour does the talking: a deep emerald, a true sapphire blue, a paler light sapphire or a shadowy ink blue, each held against a bright white gold tone.

The silver band is electroplated for that pale, cool finish, which keeps the metal looking luminous beside the stones and picks up light from a window or a candle equally well. It reads as a considered piece rather than a loud one, so it works with a plain shirt at a desk and with a dark dress at dinner.

An open back makes it easy to place: it settles between No. 6 and No. 10, on an index finger or a ring finger, worn alone for a single line of colour or set beside thinner bands. The ring weighs between 1 and 6 g, light enough to forget you have it on.
