Chainmaille! Little random things like these earrings are the result of having a limited number of jumprings to work with-- and an even smaller number of similar color and size.

Orbitals are chainmaille rings that are not hooked into anything-- they are trapped inside of other rings to be held in place. (The Helm weave which I have used in my Geometric Flower and Chainmaille Bracelet uses orbitals).

While the firework dangles are not technically orbitals, they look like it. And the little red rings on the top certainly are.
