Siam Sterling brooch & earrings

Siam “Mekhala goddess” brooch and earrings. Most likely 1940s-‘50s vintage. They were originally clip earrings but I had them modified for pierced. Also included an orphan screw-back earring with pearl, sterling too of unknown origin. This was my mothers and as such I do not know where she purchased it from. All items from my closet are used and sold as is.
