A cool, clear aquamarine opens up this ring like a fragment of sea water caught in a faceted cut. The stone's hue sits somewhere between blue and green, and its carefully cut facets draw out small flashes of light with every movement of the hand. The solitaire form stays simple and minimalist - the metal fades into the background, leaving all the attention on the stone. This is a ring that combines the character of both a solitaire and a promise ring: a modest gesture with a clear message.

For this piece, an aquamarine with even colour and clarity was chosen, free of visible inclusions that would break up the light. Good stones of this quality are becoming rarer, and their prices are rising along with precious metals, so buying a solitaire like this now makes sense from a price standpoint. The rhodium layer protects the silver from tarnishing and losing its shine for years to come. The 925 fineness confirms the purity of the alloy, and refined European silver accounts for its quality. The French maker's mark on the piece confirms the origin of the metal.

A ring like this feels right on the hand in relaxed, weekend outfits. It works well with an oversized sweater in cool grey and a soft scarf draped over the shoulders - the aquamarine then naturally draws the eye to the hand. It also suits a linen shirt and loose trousers, when you want to wear something understated yet memorable. At 1.7 g, the ring is light and almost unnoticeable on the finger, even though the aquamarine itself commands all the attention.
