This labradorite ring pairs the stone's raw, dark colour with the clean, minimalist form of a solitaire. The faceted cut breaks the surface into small planes that catch the light with every movement of the hand and throw it back as a blue, at times steely, flash - the labradorescence characteristic of the stone, visible only from certain angles. The rest of the stone stays deep and dark, which makes that flash stand out even more. Jewellers of past eras associated labradorite with calm of mind, inspiration and self-belief - today that association suits both a solitaire ring and an engagement ring equally well, since both are meant to last for years.

Each labradorite for this solitaire is examined individually, and we choose the stone whose flash reads most clearly, without random dead patches. Silver and good coloured stones get more expensive year on year, so buying a ring like this now makes sense price-wise. It is set in refined 925 silver of European quality, coated with rhodium - a hard layer that protects the surface against tarnishing and scratches, keeping the shine bright for years to come. The alloy is free of nickel and other irritating additives, so the ring can be worn without worrying about skin irritation. The piece is stamped with the French maker's mark, which guarantees the origin of the metal.

Styled for the office, this ring works well with a smooth shirt and a classic blazer in muted, cool grey or navy - the stone's blue flash brings the outfit to life with every movement of the hand, whether you're writing or shaking hands. In the evening it suits a dark dress, where the stone's deep purple undertone and cold sparkle play off the silver. The medium size and light weight of 2.4 g mean the ring wears easily, without getting in the way of everyday gestures.
