Thanks everyone! The earrings are fixed, not removable. The articulated design has a peg cup on the top with a ring below, and the diamond has a loop and peg that attaches above the bezel set diamond.
SunSeeker, I love that pendant. The bail looks so substantial and compliments that delicious pearl so well!
Hanadama, the white pearls stacked looks so Chanel! And she loved jersey knits, btw.
