Dark, almost graphite labradorite in a cabochon cut hides a surprise: as you turn your hand, a cool blue flash runs across its surface, vanishing and returning with every movement of the finger. The silver band, covered in hand-applied enamel, has a silhouette straight out of old workshops - slightly aged, with a distinctly retro character. This is a ring meant as a symbol of promise and engagement, and labradorite has long been associated with calm thinking and self-confidence, which suits the occasion for which it is chosen well.

The stone for this setting was chosen for the depth of its colour and the purity of its structure - these are what determine whether the blue flash appears at all and how long it holds the eye. Silver has risen in price in recent years, and good labradorites are becoming harder to find, so a piece of this quality and price is worth considering now. The band is made of pure, refined sterling silver 925, which thanks to European refining contains no nickel or other sensitising additives - comfort for sensitive skin remains a priority. The metal bears the maker's mark struck on the silver, registered with the French assay office, attesting to its origin.

A ring like this works well at a family celebration - paired with an elegant dress and warm candlelight, the stone's blue flash brings the hand to life without the need for extra jewelry. Classic earrings or a delicate chain around the neck are more than enough to complete the look. The big size of the stone and the weight of 5.0 g give this piece the right presence on the finger, while its vintage character means the ring holds its own next to older family jewelry, with which it is often worn on such occasions.
