This lapis lazuli ring pairs a modern, streamlined band with a stone of deep navy colour. The cabochon cut highlights its smooth surface, and golden flecks of pyrite scatter across it like tiny sparks in a night sky. Jewellers of the past associated this stone with intuition, idealism and inner harmony, which makes it a fitting choice for an engagement and promise ring.

Each lapis lazuli is carefully examined before it goes into its setting - what matters is the depth of colour and the clarity of the surface, and this kind of selection keeps quality high while keeping the price reasonable. Silver is rising in price, and good stones of this class are becoming harder to find, so buying now remains a sound decision from a price standpoint. The band is made of refined European 925 silver, coated with a layer of rhodium that protects the surface from tarnishing and dulling, so the shine lasts a long time. The alloy contains no nickel, the metal responsible for allergic reactions, so the ring does not cause allergies. The silver bears the French maker's mark - a legally protected mark registered with the assay office, which attests to the metal's origin.

In spring it pairs well with a pastel trench coat, a silk scarf in a soft shade and a light-coloured handbag - the navy of the stone brings life to a muted palette without needing further adornment. The gesture of shaking hands, or the band catching the light against the wrist inside a coat sleeve, further highlights the stone's dark colour. The medium-sized ring, weighing 3.3 g, sits lightly on the finger without weighing down the hand. It is a piece equally suited to everyday meetings and to the moment of making a promise.
