Iridescent 1-1/2" wide art glass "donut" is mostly limes with raspberry, aqua, and black accents. Handmade so it's chunky, with a silver loop that we attached to a really cool black Chinese choker. The choker measures around 16-inches long, and it is somewhat adjustable with some stretchy loops and a glass bead. The art glass is tied to the choker with a knotted cord, so you can change pendants. Perfect adornment for the little black dress.
