With Australian opal as stone of choice, Bleu sparks in blue from the sterling Industrial style "body" with an asymmetrical but cohesive design. 
The ear posts - studs- are separate from the main body where the stones are set, having as companion opalescent vintage-to-old tiny glass beads threaded in Sterling on the sides.
The size is not shy but not excessive either, and you can see it from the pictures where the earrings are on top of a standard-sized business card, compared with a USA quarter coin and the wooden carpenter ruler.
