Featured Edwardian Gold Brooch

In another one of the batches I have I found this brooch. It looks Edwardian to me but has no gold stamp on it. The stones look like emeralds with a jade dangle. Thoughts?

 

it's very pretty....

 

It has a trombone clasp with the tube hinge. I can't see a mark either, but if it's old enough it might never have had one.

 

Take it to someone who can test the metal and the stones

 

It's an odd variant on a trombone with that screw. I'd think it warrants investigation.

 

No one would use that on a piece of costume, you'd think. There's no telling what a Victorian jeweler would get up to, but I'd say odds on this comes up good.

 

So would I. And that would be very easy to wear as a pendant, too.
