The amethyst cabochon in this signet ring has a deep, saturated colour that shifts from dark purple to a cooler violet as you turn your hand. The smooth, domed surface of the stone catches light differently than a faceted cut - instead of sparkle, it gives off a calm glow that changes with every movement of the hand. The wide, rhodium-plated band of the signet ring gives the whole piece a vintage character, and the small size keeps the form light and comfortable on the hand. In old-world jewellery craft, amethyst was associated with calm and clarity of mind - an association that still resurfaces today in jewellery with a simple, considered character.

The colour and clarity of this particular amethyst determined its choice for this piece - the stone is clear, free of cloudiness, which is immediately visible with a cabochon cut. Silver is getting more expensive, and good stones of this quality are harder to find these days, so buying now makes sense price-wise. The signet ring is made of pure, refined European silver, sterling silver 925 - it is the fineness that confirms the purity of the alloy, free of nickel and other harmful additives, which is why the metal does not irritate the skin. The rhodium layer protects the surface against tarnishing and scratches, keeping the shine bright for years to come. The silver bears the French maker's mark, attesting to its origin.

Against all-black outfits - a turtleneck, a blouse or a simple sweater - this signet ring stands out as a violet point of light on the hand. In a total-black look, it's the stone that draws the eye while the rest of the outfit stays understated. It also works well with a charcoal coat or a dark blazer, where the cool grey background further emphasises the depth of the amethyst. The small, compact form of the signet ring makes it easy to wear, and its vintage character pairs well with simple, contemporary cuts of clothing.
