Pictured below are two necklaces. The long knotted one is often presented as "Deco era" 1920s "Peking glass" ,but I wonder if it isn't a lot more recent - maybe even produced currently? The beads it should be said, are really great looking and well presented with the double knots. Such a color!

The other necklace is also make with blue glass beads but these are deeper in color and seem more refined. I wonder if this might actually be a Deco era necklace. The silver work with the little foo dog links is very fine.

I would appreciate any information on either strand.

Thank you!
