Blue Onyx and Diamond Apeture Ring

14K Yellow Gold Blue Onyx and .37ctw Diamond Apeture Ring

A clear departure from traditional gemstone setting, this apeture ring is skillfully designed so that the Cylettes® pass completely through the sidewalls of the mounting. The method, exclusive to J. Kennedy Design, leaves the ends of each Cylettes® cylinder exposed and flush with the metal. With the cylinder ends open in the setting, the opportunity for light to directly pass through them is clear and ever-present. The result is that the piece of jewelry is now multi-dimensional, which affords wearers a masterfully designed creation that actually allows the gemstones to emit a richer, deeper and more magnificent color from all angles.
