Filigree Pendant With Pearls and Gemstone Cabochon

Vintage 23” goldtone metal chain with a goldtone filagree pendant - white faux pearl and a natural stone cabochon agate/simulated jade? the pendant is 2” long and 1 1/4” across. This was in my Aunt’s jewelry box for a very long time and she doesn’t remember ever wearing it… the necklace looks brand new, very pretty.
