New designs have been released in the Ziro bi-tones ring range.
Selected styles are now available with black zirconium bases and gold or sterling silver inlays. Until now, Ziro rings were limited to metal bases and a black zirconium overlay.
When zirconium is exposed to a high temperature, a chemical reaction occurs on its surface that results in a black oxidized coating. The material is said to be extremely strong and fade-resistant.
Worth & Douglas distributes a number of jewellery brands, including Karen Walker, Tahi and Lord of the Rings.
