Featured Mark on art deco sterling bracelet help please

This is superbly well made. Set with a couple of amethysts and something else I need to test. The mark reminds me slightly of Pierre Cardin but it isn't. Anyone recognise it please?

 

Pierre Cardin?

It looks similar, but I think the bracelet is way too old for that. It's not their style either.

 

Could be a diamond, an old table cut.

 

It might indeed, I shall fish out the tester.

 

It really does look like a PC mark but I’ve never seen anything like this from him. Ive only ever seen gold tone (and frankly a bit cheap looking from PC)

 

I don't see Pierre Cardin either.

In the photos it really doesn't look "superbly well made",it appears to be poorly cast with air bubbles all over.The bezels are poorly soldered onto the designed areas,much of the inside parts look unfinished with casting bubbles and no surfaces sanded smooth.

 

Way too old for Pierre Cardin. It looks like what came out of North Attleboro, MA and Providence RI in the 1920s. The style was popular so it could be from elsewhere, but I have a hunch it's an American export. Odds are the stones are glass. The white gold and platinum versions had real or lab stones, but the sterling... it's a toss-up, but I'd doubt diamonds.

 

It’s very well made. Perhaps the photos don’t show up well on your monitor.

It does need an ultrasound bath. Full of gunk.

My thought was American too, it rather reminds me of a piece I bought years ago in South Carolina.

 

At first I thought one of the stones was too small for the bezel, then I realized that what looked like part of the bezel was actually polish residue. I'm sure it will look perfect after its bath.

 

It does need a good cleaning. The straight costume ones oddly don't get this dirty. I still have my grandmother's, bought new.

 

It has nooks and crannies aplenty.

 

That mark is a little worn / distorted, but it could be Goodman.

 

This one?

Here’s a marked ring they show too.

 

Oh, that looks right, doesn't it.
