Cool aquamarine blue comes alive with every turn of the head - in these earrings, four faceted stones catch the light and throw it back in small flashes whenever a hand brushes back the hair or light falls from the side. The dangle form with its modern outline brings lightness to any look, while the slim line of the posts draws the eye toward the neckline and cheekbones without weighing down the earlobe.

Only a fraction of the vetted rough makes it into these four aquamarines - what matters is purity of colour and freedom from flaws, so the final selection is narrow and the effect is clear at first glance. Rising silver prices and the increasing scarcity of stones of this quality mean a purchase like this makes price sense today. The earrings are made of refined European 925 silver, a pure alloy free of nickel and other harmful additives, so wearing them against the skin raises no concern about irritation. A rhodium layer protects the surface against tarnishing and scratches, keeping the metal's shine bright for years to come. Each pair also carries the French maker's mark - a legally protected mark registered with the French assay office, attesting to the origin of the metal.

They come into their own in a total-black look - with a black turtleneck or a plain, unadorned blouse, when the sparkle of the aquamarine becomes the only colour in the frame and naturally draws the eye to the face. Hair worn loose to reveal the ear, or a sleek ponytail, further shows off the stone's movement with every turn of the head. This is the answer for evening occasions, when an understated outfit needs one clear, cool-toned accent near the face.
