Transformable, Something else can be changed as our mood, while the ear wires hold copper square/ish forms with an opening that are permanent, circular forms with rustic pigmented stoneware discs that add volume can be removed changing the looks to a different one.
The pictures show the square forms opening and how to insert or remove the circles with stoneware -try to find the thinner side on that circles and slide out, same to put them back in, no need to open the square openings at all!. :) 
Totally cool, lately I had been thinking in some transformable jewelry and might add some pieces in different batches for the ones that like to play with changing the looks without having to alter the pieces permanently.
The dangles can be even used as pendants separately if you want!
Copper, stoneware and nickel.
 
For measurements, the pictures show the earrings on a standard business card, a USA quarter coin, a traditional metal ruler and on the bust, a real size human mannequin -Sorry for the awful pics, it was hard to do with workers everywhere and I wanted to release this batch so I can start playing with fire again!-
