According to Wikipedia, cloisonne is "an ancient technique for decorating metalwork objects, in recent centuries using vitreous enamel, and in older periods also inlays of cut gemstones, glass, and other materials".
I love cloisonne, despite the fact that I have no idea how to pronounce it. I used to have a couple of pieces of cloisonne jewellery, and when people would ask about them I'd reply: "yes it's c... it's cl... it's clwah... it's pretty isn't it?".
The bright colours in these cloisonne earrings are beautiful:
