Featured Cameos and filigree brooch

I bought these at an Estate sale this morning. I am not very good at dating jewelry. When do y’all think these pieces were made? All are marked 10k.

 

Cameo pendant probably 1930s or so.

 

And the brooch a little earlier.

 

Test the stone on the filigree brooch, it may be glass but it may be a diamond

 

Or a white sapphire, I've a bracelet with one.

 

One of the cameos is set in a ring. That hasn't been mentioned. Also 1930s?

 

Couldn't see it, so couldn't opine.

 

Top one is the necklace, bottom one is the ring. They are a set.

 

How do you test a stone? I don’t have a gem tester.

 

They certainly are. So 30s on the ring too. White gold was popular then, although I'm going by the look of the cameos.

 

The stone in the cameo hair? Could it be diamond, sapphire, or glass as well?

 

Could be diamonds, some of them are. The stone in the only one I've ever had that was en habillé (when the cameo figure is herself wearing jewellery) fell out when I was cleaning the piece & was declared by my jeweller to be glass. Any other stone, sapphire or topaz, I think is very unlikely. No way to tell from pix.

 

You would need to acquire a gem tester, they are available on the internet. Or you could take it to a jeweler/gemologist but he/she will charge for testing.
