Mystery Mark? Art deco necklace?

Hi all! First and foremost, I had this piece appraised here. But they couldn't decipher the maker's mark and because of that had trouble dating the piece and establishing origin. Could someone help me with this? I'd really appreciate it...I've spent hours over the past 2 days pouring over MM's on the internet and can't even find anything similar. Thanks in advance for any help you can bring to the table!

What I know: the triangle stones are citrine, the black are onyx, the red are carnelian and the ones that make up the necklace are crystal quartz and all are in beautiful condition. They are set in sterling with the assay mark 935. This was verified by my jewelers, of which one was a certified gemologist

What I was told: possibly 1925 to 1930 art deco piece. German origin. I can take one picture down and put up a picture of the back if you need.

Hi everyone! First and foremost I have missed all of you. Terribly! But hey… considering I’ve been in and out of the hospitals the past month, I’d miss Mr. Mephistopheles, himself, after 15 hours of hanging around in and doctor’s offices and different hospital emergency department’s waiting rooms.

Side-note: Would someone please enlighten me as to when the ER became the ED? I asked a well-meaning charge nurse about this and was told that emergency department made more sense because it was more than a room; it was an entire department. I stared at him a moment, then pointed out that the problem wasn’t in the re-christening of the emergency room as the emergency department. It was in the calling the ER the ED. Puzzled, he asked me why that was. I explained that thanks to the never-ending stream of intimate issues covered by advertisements for the latest, newfangled prescription drugs, the only thing that I- and everyone else I polled while sitting in the waiting room for 15 hours - associated with the acronym ED happened to be “erectile dysfunction.” So that whomever sold the whole idea of using the shortened form of ED instead of ER was unintentionally causing a subconscious link between the emergency room and...well, you get where I’m going with this.

Back to the hospital waiting room. We all know I take comedic license to exaggerate. I wish I could exercise that license when I tell you I spent 15 hours in the waiting room of Duke Hospital Emergency Department. But I would be lying. I spent 15 hours there because there were absolutely no available beds. None. Nada. Niente.

That’s right. There was no room at the Inn for Carmen. I was totally empathizing with our Savior, at that moment. Of course, there were a few minor differences,. The first being Roman legionnaires were out to kill our Lord, while I was being attacked buy a full-blown bacterial infection they could’ve knocked out an entire legion or two had the Lord decided we could’ve worked in tandem at some point.

Secondly, He was offered silver gold and myrrh. Not to mention a rhythm section. I couldn’t even get a cup of soup.

Lastly, he is our Lord and Savior and I am… Well… Not. Still. A little gold and silver would’ve been nice. Or a bed. Or soup.

Once diagnosed, I was presented with bag after bag of IV antibiotic. Not quite myrrh, but probably more effective.

Side-note no. 2: I really don’t know what myrrh is except that it’s some type of rare resin-based material. I also believe. it’s worth somewhere along the line,, per ounce, of whale vomit. Seriously. For the record, I don’t need the elucidation., I just felt the need to be completely honest about the myrrh situation and my speculation as to it’s worth compared to whale vomit. MOVING ON...

Well, I really have nothing to move on to, at this point. I've somehow gone from a kidney infection to whale vomit. Where could I POSSIBLY go from here? Except OFF the internet entirely? Why in the world am I feeling that there's a lot of high-fiving going on with that decision?
