The labradorite cabochon catches the eye with a play of blue shimmer that emerges from the dark, almost graphite-like surface of the stone. The cabochon cut does not scatter this light through facets but gathers it in one spot - as the angle shifts, cool, steely flashes appear, fading and returning with the movement of the hand. The big size of the ring and its plain, modern band let the stone remain the main focus of the design, without extra details pulling attention away. This is a form close to how an engagement ring is conceived - striking, yet without excess ornament.

Only a small share of the raw material reviewed makes it into this piece - what matters is depth of colour and clarity, free of cloudiness within the stone's structure. Good labradorites are rising in price along with precious metals, and natural rough of this quality is becoming harder to find, so buying at a reasonable price makes sense right now. The setting is refined silver of European quality, sterling silver 925, free of nickel and other metals that irritate the skin - meaning the ring can be worn without fear of an allergic reaction. A rhodium layer protects the silver from tarnishing and scratches, keeping the shine bright for years to come. The piece bears a maker's mark struck into the metal, registered with the French assay office, which attests to its origin. Craftsmen of old associated labradorite with peace of mind, self-confidence and inspiration - today it stands mainly as a symbol, not a promise of effect.

For an evening out, the ring pairs well with a little black dress and a smooth silk blouse - against such a understated base, it is the stone's blue flash that draws the eye to the gesture of the hand. It is worth skipping extra bracelets on the same hand, so the cabochon has room to play with light. For daytime wear it also works well with a plain sweater in cool grey, where the labradorite naturally comes through at its strongest.
