The faceted amethyst in this ring pairs the geometric simplicity of a solitaire with a depth of colour that shifts with every movement of the hand. The cut opens up layers of purple within the stone, from pale lavender to deep violet, and light draws out flashes that were invisible a moment before. The solitaire form, with a single striking stone at its centre, stays spare and focused on what matters most. This is minimalism that needs no extra ornament, because one well-chosen amethyst is enough.

The stone for this ring was hand-selected for clarity of colour and a depth of purple that is hard to find at the same price. Silver and good amethysts get more expensive year on year, so buying a ring like this today makes sense in terms of price. The metal is vermeil - a core of refined sterling silver 925 of European quality coated in a thick layer of 18-carat gold, which is what actually touches the skin and gives comfort even with frequent wear. Compliance with the vermeil standard is confirmed by the stamped V mark, and the French maker's mark, registered with the French assay office, vouches for the metal's origin. In jewellery tradition, amethyst has been linked to calm and clarity of mind, treated as a symbol of balance.

A ring like this feels right in the evening, with a little black silk dress, when the hand remains the main focus of attention. The amethyst's purple catches the eye with every gesture, raising a glass, adjusting your hair, opening a door. Simply leave off the bracelet or a second ring, and the stone can work freely with the light of the room or restaurant. At 2.3 grams and a very small size, the ring stays light on the finger despite the stone's striking colour.
