The deep purple of the faceted amethyst catches the light with every movement of the hand, breaking it into tiny flashes deep within the stone. This solitaire ring, set in a solitaire mount, has a modern, clean silhouette - the band doesn't pull attention away from the stone, it simply frames it. Jewellers have long linked amethyst with calm and clarity of mind, and its cool purple suggests balance rather than extravagance.

Before an amethyst is set, we assess it for colour and clarity - in this stone the dark purple is even, with no clouding, which at this depth of colour is rare to find at a reasonable price. Silver and good-quality amethysts are rising in price, so buying this ring now makes sense financially. The rhodium-plated surface is hard and scratch-resistant, so the shine lasts longer, and the refined European silver of 925 fineness forms a pure alloy free of nickel, the metal that triggers allergies. The piece does not cause allergies or skin irritation. The band bears a maker's mark struck on the silver, registered with the French assay office.

This ring suits a romantic style well - worn with a lace blouse, a pastel dress or a simple white shirt, the purple of the amethyst draws the eye without being flashy. On the hand it weighs 2.5 grams, so it wears lightly despite the stone's clear presence. It pairs well with delicate jewellery on the other hand, or can stand alone as the single splash of colour in a cool, muted outfit.
