Vintage lucite beads with modern firepolished glass accents and assorted metal beads. 

These are on gold-toned earwires of dubious metallurgical composition, so if you have any metal sensitivities I would recommend upgrading to something else - the gold-filled earwires are usually a good choice for people with sensitive ears. 

I can also make these in silver wire upon request, although I only have the red beads in the gold-striped colorway.
