Cheech... this is a super sweet piece...
No clue on it as of yet... but I can smell money on this.

In fact... I can find nothing "bad" about this piece.

This would be a high on the desired list in front of prospective buyers.

It has it all...
Color...
Motif...
Style...
Precious metal...
Condition...
And yes... the "cool" mark.

This color HAS been "in" for quite awhile now as well.

Nice find. Could the stone be molded glass? The mark is similar to the three castle mark used in Denmark as an assay mark. But I don't think it is Danish.

I am thinking Bakelite.

And a rare color as well.

I looked at the Danish hallmarks the only difference I found with it is it doesn't have the numbers under the castle and I ran it under hot water to see if I could get a smell from the Bakelite as I can't find my other paste stuff to test it but I don't think it's Bakelite it's a hard plastic type and not glass

Ok I found the simichrome polish and it did not turn yellow so no Bakelite
