Featured Silver stone brooch/pendant

Greetings,

I’ve had this one for a long time with no clear memory on how it came to be in my possession. It’s a small one inch brooch/pendant combo. No markings anywhere, tests positive for silver. I think the “stone” is a composite but frankly I don’t know. One of the heart leaves is slightly raised in an interesting pop up design. Can anyone tell me anything else about it?

 

Pretty sure it wasn't designed with the "pop up" feature on one of the stones. Looking at the setting, it's flush in the upper corner. There is usually a spongy type backing when stones are set and this one may have been subject to moisture, causing the backing to swell.
I agree, probably a composite but no solid ideas on what it may be.

 

Turquoise chips in resin.

 

Agree. BMRT, can you push it back gently, without damaging it? It is prone to damage the way it is, I don't know if that resin can withstand any acidental knocks.
It is cute, but whoever put the resin with turquoise chips in wasn't very careful anyway, there are blobs in between the leaves.

 

I tried to push it back in or wiggle it up and it does not budge. If it was accidentally pushed out by moisture it had to have happened a long time ago and now it’s very much stuck like this!

 

Looks like a Mexican piece to me.
