The cabochon labradorite on this ring draws out a deep, dark glow from the stone, one where a blue flash suddenly ignites - simply tilt your hand in the light to see that reflection travel across the surface like a narrow band of cool brilliance. The classic, understated shape of the band does not compete with the stone, letting it lead the eye with every movement of the hand. Old-time jewellers linked labradorite with a calm mind and self-belief, which makes it a fitting choice for a wedding and engagement ring.

Every stone is examined under light before being set, checking the depth of colour and the clarity of its structure before it goes into the silver. Good labradorites are becoming harder to find, and silver has risen in price in recent years, so buying now makes sense from a price standpoint. The setting is made of refined sterling silver 925 of high alloy purity, free of nickel and other harmful additives that could irritate the skin. A rhodium layer protects the surface from tarnishing and keeps the metal's shine lasting for a long time. On the inside of the band you can see the French maker's mark struck on the piece and registered with the assay office, attesting to the origin of the silver. Its very big size and weight of 6.9 grams give the ring a solid, noticeable presence on the finger.

For everyday wear it looks good with an oversized sweater in cool grey and a soft scarf tied at the neck - the dark purple of the labradorite brings life to these muted, weekend layers. Wool trousers and flat shoes suit it well too, when ease of movement matters more than stiff elegance. In the evening, the same stone works just as well with a simple, classic dress, keeping its character regardless of the occasion.
