I posted this in the jewelry forum and someone suggested that you guys may have an idea who this maker may be. I am attaching pictures of both the necklace as well as the signature. Handwriting this bad shouldn't be put in silver, lol! Thanks for your help!
I'll see what I can come up with. That is a great piece of jewelry. I don't know if it would be termed Brutalist or just Mid Century Modern. Tried to lighten the photo a bit for better details.
