This aquamarine signet ring pairs a raw, geometric ring form with the cool, glassy blue of the stone. The faceted cut breaks the light into fine glints, and the aquamarine's colour recalls seawater right at the shoreline - bright, clear, without a trace of cloudiness. The small size of the ring and the delicate line of the band give the piece a vintage character, as though it came from a family jewellery box, even though it was made today.

The stone for this ring was chosen by hand, its colour and clarity checked against the light before it was set. Prices for silver and good coloured stones have been rising for some time, so a purchase like this makes sense today. For this price you get a carefully chosen stone and solid craftsmanship, which is not a given in this segment. The band is coated with a layer of rhodium - a hard metal resistant to scratching, which keeps the silver from tarnishing or going dull for a long time. The silver itself is refined, pure, sterling silver 925, and the alloy, free of nickel and harmful additives, lets you wear the ring without worrying about skin irritation. The piece is stamped with the French maker's mark, which attests the origin of the silver.

A signet ring like this sits well on the hand with a lace blouse or a dress in powder pink or blue - colours from the same soft register as the stone itself. It also suits delicate, romantic patterns - embroidery, pleating, thin ruffles at a dress neckline. Wear it on the index or ring finger, where it catches the eye with every gesture - smoothing your hair, holding a cup, writing a note by hand. The cool blue of the aquamarine pairs well with warm shades of beige and cream in the rest of the outfit.
