Need help to identify these pieces of jewelry

I have collected a lot of things through the years and I will need you (again) to help identify these vintage necklaces. The ball clasp is 14K gold on the necklace with the little flowers. I know they are not rare or impressive but I just want to know what they are! Thanks in advance!

 

Beautiful collection, Anouchka !
I believe the beads in the second picture are called Wedding Cake beads, the red/blue ones are Italian Millefiori (thousand flowers) beads and the pink-reddish beads I've seen them as Aventurine/Sommerso beads. These are the terms I've found online, not sure if- for example- the Wedding Cake beads should have a special pattern on them or not in order to be truly a Wedding Cake bead (if not, probably the last picture could be Wedding Cake too). I'm sure somebody more knowledgeably will come soon and help you with the rest..

 

Oh you are quite knowledgeable! Thank you so much for all the information!
