This amethyst engagement ring plays with deep purple with every turn of the hand. The cabochon-cut stone has a smooth, domed surface that gathers light in one point and brightens the colour from within - deeper inside you can see darker, violet flashes, while nearer the edge it turns cooler, almost plum. The big size of the stone works well with the boho-inspired, vintage-styled form - the ring has a bold, somewhat relaxed silhouette, further from a classic solitaire and closer to an ornamental, artistic setting.

For this piece we chose an amethyst with an exceptionally even, saturated colour and a clean interior, free of cloudy discolouration - it was precisely this clarity and depth of colour that decided its selection. Silver and good coloured stones get more expensive year on year, so buying a ring like this today is a sound choice price-wise. It is set in refined sterling silver 925 of European quality, hard and resistant to tarnishing, and the nickel-free alloy, free of other harmful additives, does not irritate the skin. The French maker's mark on the band confirms the origin of the metal. In old jewellery-making tradition amethyst was linked to a symbol of calm and clarity of mind, and in engagement tradition it was sometimes chosen precisely for this calm, composed colour.

Day to day this ring sits well on the hand alongside soft knitwear - a chunky sweater in grey or broken white gives the amethyst room, and the purple comes to the fore with every gesture of the hand. In monochrome outfits, where the rest of the look holds to one tone, the stone naturally draws the eye without needing extra ornament. It also suits relaxed, boho-leaning pieces - linen tunics or loose cardigans - where it settles into the whole look without standing sharply apart. This is a ring for a hand that likes to wear a story, not just jewellery.
