The pure, cool blue of the aquamarine catches the eye at once in this modern ring for the hand. The faceted cut breaks light into small glints that shift in intensity with every turn of the hand, now brighter, now deeper. Twelve cubic zirconias surround the central stone with a delicate halo of sparkle, without drawing attention away from it. The form is simple and distinctly contemporary, which makes it work equally well as an engagement ring and as a wedding choice for years to come.

An aquamarine like this - clean, richly coloured, free of flaws that would cloud its clarity - is easy to overlook among the many stones out there, and a second example this good is hard to find. Silver and fine coloured stones rise in price year after year, so buying this ring today makes sense financially. It is set in rhodium-plated silver: the rhodium layer is hard, resistant to scratching and protects the surface against tarnishing and blackening for a long time. The silver itself comes from European refining, and the 925 fineness confirms the purity of the alloy, free of nickel and additives that could irritate the skin. The French maker's mark on the piece guarantees the quality and origin of the precious metal.

In the city, it sits well on a hand dressed in jeans and a white shirt, with a leather jacket thrown over the top adding a modern edge to the whole look. In the evening, simply swap the shirt for a silk blouse and the ring takes on a more festive character. The cool blue of the aquamarine pairs well with light accents - silver, white, pale denim. This is a ring equally suited to an engagement and as a wedding band on the big day.
