Vintage Gold Over Sterling Silver Necklace & Circle Pendant Signed OS 925 Italy

Description

Beautiful Gold Over Sterling Silver Necklace & Pendant Signed O.S. 925 Italy.
Weighs about 20g.
The necklace measures about 16" long & can be extended to 18".
I think it's called an Omega chain & there's an oval link extender.
There is a very small separation between a link, see pics 9 & 10. Probably can be burnished back together.
The pendant is about 1.5" in diameter & is beautifully decorated with crystals in amber, milky AB & clear AB tones.
A very unique statement piece.
I try to describe everything as clearly & accurately as I can however there may be flaws or imperfections that I miss, so...
Please look closely at the pics as they are part of the description & if you have any questions feel free to ask.
Thanks for looking!
