This is a beautiful gilt gold tone choker necklace that is reminiscent of the Renaissance or Byzantine era. The chain looks like 1960’s to me. The cabochon settings look like a blend of tigers eye, red & black onyx and the green may be glass or possibly green onyx. Unfortunately, I don’t know a whole lot about this necklace and this is not stamped or signed. I wasn’t able to find anything similar online. The sections of the necklace with the settings are clearly hand forged. A very nice eye catching piece! End to end @ 16” (it can be adjusted to be smaller) I am always open to offers. Thanks for looking! Tags: vintage necklace, Byzantine era, renaissance jewelry, renaissance choker, gilt gold choker, cabochon, chunky choker
