Can anyone tell me what are these antique silver jewellery?

[Aurora et luna]

I am pretty sure the first one is a scent bottle, however I am not sure what are the functions of the other two items.
They are all suppose to be jewellery however I don't know how's it worn.

Thanks Spannermonkey!
I have googled Vasta and there are no results
What do you put inside a Vasta?
