This is such a pretty, dainty ring! It's made from genuine .925 Sterling Silver (that's 92.5% pure silver mixed with alloys for strength), so you know it's quality that will last, not cheap plated stuff. The design features a lovely teardrop shape with a sparkling clear Cubic Zirconia (CZ) stone paired with a beautiful blue simulated opal. The band is simple and elegant, making the stones the real stars. This one is a US size 5. It's a versatile piece you can wear every day – dress it up or keep it casual. We make sure every piece is new and inspected for quality before it ships. Plus, you get fast shipping and the backing of Amazon's refund policy for total peace of mind. A perfect little gift for yourself or someone special who loves unique, feminine silver jewelry.
