Two labradorites set into the signet shimmer with a steely, blue reflection that flickers on and off with every turn of the hand. Against the stone's dark background, this cool flash looks different in daylight than under lamplight, and the cabochon cut lets it flow across the surface without a break. The simple, classic form of the signet does not draw attention away from this effect - the substantial band stays in the background, and the labradorite leads the eye. Jewellers across many traditions have linked this stone with clarity of mind and confidence in one's own decisions, which suits a signet worn on a permanent basis.

Each labradorite is examined and turned in the light and assessed for the depth of its reflection before it goes into the setting - the stone's fine finish and natural character go hand in hand here with a sensible price. Silver and good stones are steadily rising in price, and labradorites with such a pronounced play of light are getting harder to find, so buying this piece today makes sense price-wise. The signet is made of refined European 925 silver, coated with a layer of rhodium that protects the surface against tarnishing, dulling and scratches, keeping the metal's shine clear for years to come. The pure alloy, free of nickel and other irritating additives, means that even sensitive skin does not react to contact with the metal. The silver, bearing the French maker's mark, attests to the metal's origin and to the craftsmanship of its making.

The medium-sized signet, weighing 5.5 g, sits well on the hand without weighing down its movement. It suits everyday men's knitwear - a soft grey or navy sweater, a shirt with a rolled-up sleeve, monochrome outfits without extra ornamentation. On a hand emerging from a dark wool sleeve, the steely reflection of the labradorite stands out clearly against the background. This is a signet worn every day, its character only becoming apparent on a closer look at the stone.
