The faceted sapphire in this solitaire catches the light in narrow, geometric facets and answers back with a deep, saturated navy glow. It's a small stone, but dense in colour - as the hand moves, short flashes of a deeper violet appear. The ring's form is simple and centred on a single stone, with no additional detailing, which suits the minimalist character of the whole piece. Sapphire has long been associated with gravitas and focus, and its cool tone works well against the plain, rhodium-plated band.

We examine every sapphire for this collection individually and select the one where colour and clarity are most even, so despite its small size the stone still looks dense and refined. Silver and good coloured stones get more expensive year after year, and evenly coloured sapphires are getting harder to find at a reasonable price, so this purchase makes sense today. At this price you get a carefully selected stone and solid, rhodium-plated craftsmanship, not a compromise on either. Rhodium forms a hard, resistant coating that protects the silver from tarnishing and scratches, so the shine stays bright for years to come. Beneath it lies pure, refined European silver of 925 fineness, free of nickel and other harmful additives, so the ring does not irritate the skin. On the inner side of the band the French maker's mark is stamped, attesting to the origin of the metal.

On the hand, this solitaire works best in everyday, understated outfits. A linen shirt in a natural shade, a loose-cut cotton dress or a simple cotton sweater - this is the backdrop against which the navy sapphire draws the eye without excess sparkle. The gesture of reaching for a cup or turning a page is enough for the stone to catch a brief flash of light. Its very small size and weight of 1.8 grams mean the ring wears light, almost unnoticeable, until it catches the light.
