Vintage Pink Natural Stone Pendant hook bail hammered 925 silver teardrop shape

Vintage Pink Natural Stone Pendant hammered 925 silver setting, marked on the back hook bail teardrop shape most pics taken in macro mode i can tell it is a natural stone based on the black irregular occlusions in the surface, but i do not know what the actual stone is. this has been sitting in my jewelry box for over 2 decades. i have no recollection of when or where i got it from. it was still wrapped in its original packaging, but had tarnished quite a bit. i cleaned it up, and then repackaged it for you. approximately 1.5" length, 1" width (see pics) questions? please ask!
