Vintage Agate & Pressed Metal Pendant Necklace!

Rare beauty! The first photo is taken in the sun so you can see the multiple rings present and the translucent amber color of the agate. The top portion has been hollowed out and set with a beautiful pressed metal floral motif, very similar to an art nouveau piece. I believe this piece is from the ‘60s or ‘70s and is in beautiful condition. There is wear/tarnish on the gold tone - look at pics carefully! Pendant has 2 1/2” drop; chain is 20”.
