The amethyst cabochon in this ring carries a deep, rich purple that catches the light differently with every turn of the hand. Ten small cubic zirconia stones surround it in a delicate row of sparkle, echoing the vintage silhouette of the setting - slightly ridged, dense in form, as if lifted from an old jewelry box. The big size of the stone means the ring sits well on the finger and gives the hand a clear presence. Amethyst has long been linked with calm and clarity of mind, which makes it a popular choice for wedding and engagement rings.

Each amethyst in this collection was inspected individually and chosen for depth of colour and clarity, so quality here goes hand in hand with a sensible price. Silver and good coloured stones get more expensive year on year, so buying this ring now makes sense price-wise. The setting is made of refined European silver 925, free of nickel and other irritating additives, which matters for skin that is sensitive on a daily basis. A rhodium layer protects the surface against tarnishing and scratches, so the ring needs little cleaning and keeps its shine for a long time. The piece is stamped with the French maker's mark, which attests the origin of the silver.

For summer, this ring brings a vintage touch to a linen dress in a light shade of ecru or sandy beige - the amethyst's purple brings life to a muted, summery look. It also works well with a simple cotton shirt with rolled-up sleeves, when the hand stays at the centre of attention, for instance during a handshake at a wedding celebration. Cool grey accessories - a bag, sandals or complementary jewellery - pair nicely with the stone's warm glow. This is a ring that accompanies important moments and everyday gestures equally well.
