Combining over 100.000 carats of vividly-hued blue sapphires, this breathtaking necklace showcases the coveted invisible setting design. Also known as the mystery setting, this innovative design style was patented in 1933 and showcases an innovative way of setting precious stones to preserve their beauty. Its secret lies in its gold rails, into which stones – expressly and meticulously cut – are individually inserted. This mesmerizing technique makes the metal mechanics of a jewelry piece entirely invisible. Exquisite colored gemstones are each placed side-by-side in these settings, creating dazzling and unbroken swathes of color free from flashes of metal. Aided by this ingenious design, this beautiful bevy of deep blue sapphires creates a striking, saturated effect. The unique design emanates with elegance and refinement. The stunning sapphires are accented by a border of diamonds and the necklace is punctuated by dramatic drop, created by invisibly set diamonds. The sparkling white diamonds total approximately 4.00 carats. Set with 18K white gold. 17" length
