Ippolita Rock Candy 18K yellow gold Sabbia 5 disc mother of pearl/shell cutout overlay station necklace.
I am the original owner and can attest that it was worn a couple of times.
Total length is 18", can be worn at the 16" link.
Two discs are 15mm, 3 are 19mm, all show beautiful iridescence, with lovely color transitioning depending on the light and backing, no signs of use.
