Deep and distinctly modern, this engagement ring draws the eye to a single, carefully cut labradorite cabochon. Against the stone's dark, almost graphite background, flashes of cool blue light appear - sometimes steely, depending on the angle of the light. This phenomenon, known as labradorescence, is best seen precisely in the cabochon cut, which doesn't scatter the reflection into facets but lets it glide freely across the surface. The simple, full band and the very big size of the stone give the hand a striking yet calm silhouette - free of unnecessary embellishment, with all attention drawn to the play of light.

Every labradorite for this collection was examined individually before being set - what matters is the intensity and clarity of the reflection, not just the colour alone. Silver and good stones get more expensive year on year, and labradorites with such a richly saturated sheen are becoming harder to find, so the current price of this ring remains reasonable. Refined silver of European quality is coated with a layer of rhodium, which protects the surface from tarnishing and blackening - the shine stays bright for years. The 925 fineness confirms the purity of the alloy, free of nickel and harmful additives, so the metal does not irritate the skin. The French maker's mark on the piece attests to the origin of the silver. In jewellery tradition, labradorite has been associated with calm of mind and confidence in one's own decisions - symbolism readily linked to the moment of engagement.

It comes into its own in a total-black look: against a black turtleneck or a simple top, the hand wearing the ring becomes the point where the light gathers. The cool grey of a sweater or coat further sets off the stone's blue tone rather than competing with it. This is a ring equally at ease in an everyday gesture of the hand and in a subdued evening look.
