Sterling Silver is an alloy that contains 92.5% silver and 7.5% copper. It's strong but malleable nature makes it a popular choice for design, while it's high-shine qualities give it an attractive look.
Stacking rings are made to be worn together. Mix slim plain bands with tiny hearts, stars and wishbones, add a cubic zirconia band for sparkle, and finish with a hammered or twisted band for texture. All in sterling silver and UK sizes, and half of them cost £20 or less, so a stack is easy to build.
