This engagement and promise ring with lapis lazuli pairs a modern, clean form with the stone's deep colour. The lapis lazuli cabochon shows a rich, deep navy hue threaded with fine flecks of pyrite - as if a touch of gold dust had been scattered through it. On the finger the form stays light and clearly defined, with no unnecessary flourishes, so all the attention remains on the stone.

We assess every lapis lazuli for colour and clarity before it goes into its silver setting, which is why this ring features a natural stone of exceptional quality at a reasonable price. Silver and good stones are rising in price, and lapis lazuli of this quality is becoming harder to find, so buying now makes sense price-wise. The setting is made of refined European silver, and the 925 fineness confirms the purity of the alloy - free of nickel and harmful additives, so the metal is gentle on the skin. The rhodium coating is hard and scratch-resistant, so the ring's shine does not fade over time. The piece is stamped with the French maker's mark, which guarantees the origin of the metal.

Lapis lazuli has long been associated with intuition, idealism and harmony, making this ring a fitting choice for an engagement or as a promise ring. For everyday wear, it pairs well with a soft, chunky-knit sweater in shades of grey or navy - a monochrome outfit lets the stone's colour shine fully on the hand. It also works well with a simple shirt and loose trousers, when you want a calm, modern elegance without unnecessary accessories. At 4.6 grams and a medium size, the ring wears comfortably without weighing down the hand, and the navy colour of the lapis lazuli remains a clear focal point in any outfit.
