A turquoise cabochon opens up this ring like a window onto pure, saturated blue - no grey undertones, no shadows, just the even colour that only stone from the Sleeping Beauty mine in Arizona can give. Sixteen small cubic zirconia stones surround it, forming a delicate setting that adds sparkle without taking precedence away from the turquoise. The ring's vintage silhouette - gently rounded, densely carved - recalls forms from decades past, read today as romantic and personal, which is why it works well as an engagement and promise ring.

This particular piece was chosen for the purity of its colour - Arizona turquoise free of flaws and discoloration reaches the setting less often than one might think, and its price is rising along with the price of silver and other precious metals. That makes this ring, at its current price, a sensible choice today. Set in rhodium silver, it gains extra protection: rhodium is hard and scratch-resistant, so the surface won't tarnish or dull over time. The metal is refined European silver, sterling silver 925 - a pure alloy free of nickel and other harmful additives, which doesn't irritate the skin. The French maker's mark stamped on the piece attests the origin of this metal.

On the hand, it looks best paired with soft knitwear - a sweater in cool grey or a cream turtleneck - where the blue of the turquoise immediately catches the eye. It also pairs well with other rhodium silver rings worn together, in a monochromatic silver composition. With a simple gesture of the hand, over a cup of coffee or in conversation, the stone is the first thing you notice. This is a medium-size ring weighing 3.2 grams - light on the finger, yet distinct in character.
