Four lapis lazuli cabochons sit in a tight row, surrounded by four cubic zirconia stones that add a delicate sparkle. The stone's navy hue is dense and deep, with fine golden flecks across its surface reminiscent of scattered pyrite. This stone has long been associated with idealism, intuition and harmony - an association that suits a promise ring well. The modern, geometric setting doesn't draw attention away from the stone, but quietly guides the eye across it along the hand.

Each cabochon is inspected individually before being set - what matters is even colour and a clean surface, free of discolouration. Silver and good stones are steadily rising in price, and pieces of this quality are becoming harder to find, so this price makes sense today. The ring weighs 2.3 grams and is made of pure, refined sterling silver 925 - it is the fineness mark that attests to the purity of the alloy, free of nickel and additives that could irritate the skin. A rhodium coating protects the silver against tarnishing and scratches, so the shine lasts long despite everyday wear. The piece bears a maker's mark struck on the silver, registered with the French assay office, which attests to the metal's origin.

At the office, the ring pairs well with a smooth shirt and a blazer in muted grey or navy - the stone's navy tone subtly echoes the cool shade of the outfit without demanding attention. It also works with a simple ecru sweater, where the colour contrast does all the work. This is a medium-sized ring, comfortable for everyday wear, yet striking enough for a meeting or a dinner after work.
