Vintage Bristol blue glass Art Deco necklace - brass chain, beads and ornate floral bead caps

Fantastic Art Deco bright blue glass and brass / gold tone metal chunky beaded necklace. 

The blue beads are very like Louis Rousselet beads (made in France), but the ornate brass moulded beads and gorgeous bead caps are not ones I recognise as Rousselet components. This could easily be a Czech piece rather than French. 

The necklace has a length of about 18.5 inches and fastens with a secure spring ring clasp. It is in very good vintage condition.
