Product Description:Blue glass bottle necklace ~ comprising a sweet little 'diamond' shaped glass bottle vial, a gorgeous beaded dangle including crystal faceted beads in various shades of blue, and a tiny Tibetan silver puffed heart charm. The bottle has a screw top which opens. It doesn't have a massive capacity, although you may get a couple of drops of a favourite scent in there!

If 20" is not a suitable length for you, please do let me know - I am happy to offer you any length chain if preferred.
