A ring set with three amethysts draws the eye with the depth of its violet, which shifts in hue with every turn of the hand. The faceted cut scatters light into fine flashes - from cool purple to a warmer, almost burgundy tone - and gives the piece a retro character close to the jewellery craft of several decades past. Three amethysts arranged in a row form a composition associated equally with everyday elegance and ceremonial refinement.

All three stones share a well-matched, deep colour - the result of careful selection that is immediately apparent. Good amethysts are becoming increasingly rare, and silver prices continue to rise, so this price remains exceptionally reasonable. They are set in refined sterling silver 925: an alloy free from allergenic metal additives, which can be worn without concern about irritation. A thin layer of rhodium maintains a bright polish and protects the silver from tarnishing for years. The piece is stamped with the French maker's mark establishing the origin of the piece, registered at the French assay office.

In the office, the ring works well with a jacket in graphite or navy - the violet of the amethysts enlivens a muted palette without breaking its tone. Against a plain shirt in white or ecru, the three stones draw the eye to themselves when the hand reaches for a pen or a cup. In jewellery tradition, amethyst was associated with calm and a clear mind - an association that suits a piece of such a composed, balanced form.
