Antique 1940s Siam Sterling Silver Pendant

My grandmother had this elegant Siam silver pendant since 1940s. In great preowned condition. The pendant still shiny with minor scratch from being worn. About 1.5x1 inch. Stamp in the back 88%. Pair with silver chain or white gold chain (that's how I wear it) and ready to go. A little polish work will bring its glossy look back to original shine. Thanks.
