Help with maker’s mark on Sterling Bauhaus style necklace, please.

Does anyone know this maker’s mark? The necklace is sterling silver with 9k gold, set with a white and green solid opal. The opal is probably a Slovakian precious opal.

The necklace looks either German or Danish to me, and I think I’ve seen the mark before, just can’t remember where.The mark is tiny.

 

Very pretty piece.
I can make out the 925, but not sure what I see in the triangle.
Maybe polish it a little so the mark stands out better. Also rotate to the right, I think it is on its side.

 

If it just marked 925 like that it is not all that old. Of course, since I am pretty old myself, not all that old goes back a fair few years.

 

Thanks.
It has been polished, but has an oxidized finish which looks nice but is a problem when trying to identify the mark. I also thought the mark was on its side, but took the 925 as an orientation point. Here is another view.

 

I had a similar piece which was Polish. Blowed if I remember the maker.

 

Apparently the 925 mark was already used in the late 1800's:

I have certainly seen pre-Bauhaus jewellery with the mark. I decided to call this Bauhaus style rather than Bauhaus, because I don't know the exact period. The oxidized finish was also used in the Bauhaus period, but I hope the mark will tell us more.

 

Thanks, it could be Polish of course. Do you remember if it had the same mark? Polish jewellery usually has that peasant girl mark though.

 

9 karat usually means British, but this doesn't have British hallmarks either. Canadian would make sense.

 

Honey, it's silver, not gold.

I can't remember for the life of me what the mark was on the piece I had.

 

OP writes.....The necklace is sterling silver with 9k gold,

Darlin'...let the girl have her say !!...

 

I have no valid reason to even ask, but with the opal, what about Australian?

 

9 karat is used in many countries, all over the world. I live in The Netherlands, we hardly see any Canadian jewellery overhere, but you never know.

I think Australia is still the largest producer of precious opals, although Ethiopia is catching up. Non-precious opals are found in most countries of the world. Precious opals are more rare but they are found in all continents.
This opal looks very Slovakian, pure white with a large green flash. The Dubník area in Slovakia is reputed to be the oldest opal mining region in the world:

Most opals in Roman times were Slovakian. I think this necklace is central or northern European, Slovakia is in central Europe.

 

If the pendant can be dated,maybe the opal's origin can be guessed at for location.The Slovakian mines were only re-opened in 2012 and a very large portion of Australian opal is white base with green flash.

 

According to my information, the Slovakian opal mines were closed from 1918 - 1992. I know of several Dutch jewellery designers who still had Slovakian opals in stock well into the 1970's, this is one of the reasons I said it could be Slovakian, along with the appearance.
I grew up in Australia, with a mother who was opal mad. This little opal does not feel Australian, but my feeling could be wrong. I don't know of Australian opals which have just one green flash, but then again I don't know all Australian opals.
I would love to know more about the mark, if I ever find out I may also be able to find out about the origin of the opal.
