AeroDiamonds releases their diamonds from metal mountings to allow the maximum amount of brilliance of the diamond by piercing them with a platinum ring letting them dangle freely. The "Opus" collection is inspired by music. As music blends different notes and compositions together to make something beautiful, this collection aims to blend diamonds and colored gemstones together. This particular necklace is made of solid 18kt white gold and elegantly blends rich blue sapphire's and brilliant ice-white diamonds together dangling from each other. There are 5 sapphire's weighing 1.89 carats total and 5 diamonds weighing .38 carats total. The necklace is unique in that it measures 18 1/2" yet you can adjust the length of this to anything under 18 1/2" that you desire using a sliding ring mechanism. This lovely and unique necklace is Brand New!
