Deep and understated, this labradorite ring evokes the feel of vintage jewelry, though its form stays simple and light on the finger. The cabochon-cut stone hides a dark, almost graphite background, across which streaks of blue and steely light shift with every movement of the hand. The smooth dome of the cabochon doesn't scatter the light into tiny sparkles, but gathers it into a single, travelling glow. A band with a vintage motif frames the stone gently, leaving it all the room it needs to play with reflection.

Before it ever reaches its setting, every labradorite is judged on the depth of its background and the clarity of its blue flash - only a stone that meets this standard guarantees high quality at a sensible price. Good labradorites are getting harder to find, and silver is rising in price, which makes this the right time to buy. The stone is set in refined European sterling silver 925, free of nickel and other allergenic additives, so it can be worn without worrying about skin irritation. A layer of rhodium protects the surface against tarnishing and keeps its bright shine for years to come, and the European precision of the workmanship shows in every detail of the setting. The metal is stamped with the French maker's mark - a legally protected mark registered with the assay office in France, attesting to its origin.

Labradorite has long been associated with peace of mind and self-belief, and has also served as a symbol of inspiration for artists and craftsmen. As an engagement ring, it therefore carries a meaning that goes beyond the stone's beauty alone. It looks best in everyday, understated outfits: with a soft, chunky-knit sweater, or in looks kept to a single tone of grey or broken white. It's against just such a muted backdrop that the labradorite cabochon draws the eye most strongly, revealing its blue flash with every movement of the hand.
