Vintage Art Deco Necklace, 12k gold with Half Moon Pendant fresh water pearls

Vintage  12k Very Unique design featuring  Beautiful design includes a curved frame with freshwater pearls set along the outer edge, and an inner simi circular detail. The pendant is attached to chain with lobster clasp.  18.5” in length with 2” extender. Very Art Deco! Update,  the measurements of the pendant are approximately 2” across the top and 1” from top to bottom. I’ve just added pictures of the measurements. I did not have time to polish the pendant before taking pictures. It’s been stored for a while. A good wipe down with a polishing cloth will bring it back to its brilliant shine. If sold i will make sure it’s bright and shiny. It doesn’t tarnish, but after being stored for a long time the oils from my hands bring down the shine. Very easy to clean up.
