Vintage in shape and romantic in spirit, this ring builds its character around a moonstone set in a cabochon cut. This cut leaves the surface smooth rather than cutting it into facets, so as your hand moves, blue flashes ripple across the stone - the adularescence effect, appearing and disappearing with every gesture. Old-time jewellers associated this stone with intuition and inner reflection, and in an engagement ring that symbolism takes on extra meaning. The surround, full of arches and small details, underlines the retro pedigree of the whole design.

Only moonstones examined and hand-selected for clarity and the intensity of their reflection go into this ring, which is why, with such a big setting, every centimetre of surface matters. Good stones of this quality are harder to find today, since their availability is limited by nature itself, and silver prices are rising in parallel - which makes buying at today's price worthwhile. The setting is refined European silver 925, coated with a layer of rhodium that is hard and scratch-resistant, so the metal's shine lasts long without turning dull. The silver bears a maker's mark registered with the French assay office, attesting to the metal's origin. A pure alloy free of nickel and other irritating additives keeps it comfortable even for sensitive skin.

It speaks loudest in an all-black outfit - a black turtleneck or a simple silk blouse make a backdrop against which the stone's blue flash immediately draws the eye. A hand in motion, whether holding a glass or fixing your hair, naturally shows off the cabochon and its shifting glow. The ring also pairs well with a dark winter coat, when the cool grey of the accessories only deepens the blue. This is a big, striking setting size - made for a hand that wants to wear something more than just a plain band.
