This solitaire ring brings a violet spark to a clean, minimalist form. The faceted amethyst catches light from every angle, its violet glow shifting from a lighter tone at the facet edges to a deeper, dark purple at the stone's centre. The very small size keeps the ring light on the hand, and the understated setting lets the stone stay the focus. Amethyst has long been linked to calm and clarity of mind, making it a fitting gift for someone who values balance.

A stone like this - clean, richly saturated in violet, free of flaws that would break up the play of light - is easy to overlook, and finding another this good takes patience. Silver and precious metals rise in price year after year, so a well-chosen stone at a sensible price makes sense today. The core of the ring is pure, refined sterling silver 925, coated in a thick layer of 18-carat gold to the French vermeil standard - it is gold, not silver, that touches the skin, as confirmed by the stamped V mark. The alloy stays free of harmful metal additives, so the skin has no reason to react. The French maker's mark on the piece attests to the origin of the silver used to make it.

For an evening out, this ring pairs well with the little black dress and a silk blouse, worn without extra jewellery on the wrist - the amethyst's violet brings life to muted black as the hand lifts a glass or rests on a chair back at dinner. It also works well with a satin blouse in a cool grey shade, where the stone takes on even more depth. The simple band line keeps attention on the amethyst, and the stone's very small size makes this a ring equally suited to everyday wear and special occasions.
