Blue Florets and Pendant Beads Strand

Here's yet another blue beauty. Composed from the same hoard of beads and florets as that in earlier posts. The central disk pendant (2.5cm) in this set bears remarkable resemblance to the cover picture in A Bead Timeline. Not exactly the same, the main difference being the siting of the stringing perforation. The example in A Bead timeline p39 is dated to 1,500 BC. and comes from the Late Bronze Age of West Asia. However my piece came from a Chinese source and seller thinks its vintaage should be Song or Yuan period. For all I know (and hope) it may well be a Han piece especially the central pendant.
