sorry to miss the big recent cloisonne thread but these beads may still be of interest - its a very long tassell necklace, originally on silk which disintegrated so i rethreaded the whole necklace with a similar but stronger braid and copied the style, layout, colour and proportions as exactly as possible. -there never was a clasp.
the largest beads are 18-20mm diameter, smaller ones about 12mm.
whole thing hangs well below the waist.
