This beaded bib was done on a up cycled denim fabric remnant, as part of a series of 3 each in different colors, and it hangs from a turquoise color synthetic rubber that closes with a silver tone lobster claw, and little chain to adjust length a bit. The stones have such great colors, very vibrant. They are the flat marble kind. 
All the edges are secured, sewn and beaded. 
The last picture shows how I did the backs on these.
