Featured Anyone recognise the maker's mark of this sterling Edwardian bar brooch?

Hi all! Picked up this little sterling bar brooch recently. I think it's likely Edwardian or a little later. The stones are glass. First time picking something up with this earlier safety clasp, it's interesting! Does anyone recognise the maker's mark? Thanks for any info as always

 

Very pretty!

 

That almost looks like the top half of a dragon head in that mark.

 

I tried but could not find a US maker with a mark with this sort of bottom.

 

Yes, I see what you mean! It's got me stumped for sure

 

Thanks for trying, I couldn't either!

 

Spiedel only made (or makes) watches from what I can see. There is no silver mark for them in any of the major lists.

 

Ah, not in the US then? That mark is for gold.

A German maker would be unlikely to use "sterling?"

 

Some big German manufacturers marked "sterling" for export to certain countries. But this isn't the Speidel mark.
