Help with age and origins of a few pieces

these are a couple of pieces I have been hoarding over the last month. Just want to know more about them. The two big pieces are marked only 925. The long gold pin with purple stone actually tests as gold but has no marks. The small cameo piece looks to be at least gold filled with another metal on the back, no mark

 

Think the first one goes with the stone on top & would fall into the Halley's comet family of brooches.

The cameo is W. German glass, but brooch just as likely to have been assembled elsewhere; the cameos were exported far & wide & incorporated in jewellery by many, many makers.

 

Third piece, the pendant with yellow & green stones, is quite modern. Have seen similar jewellery coming out of India but also, I think, Indonesia (if not China). Some of the other jewellery buffs may have a better idea.

 

Thank you Bronson!

 

Darn auto correct Bronwen

 

Of course, this is probably the most comet-like orientation:



but the head downward position means gravity is working against the pin. I have a cameo in a setting of this shape, profile of a man, that would look odd placed in any way other than straight up.

 

I very much like the second one. It looks like the maker slightly let it design itself!. Very striking.

 

In this case I would say Bali, Indonesia.
