i have no clue what this says. Hoping for directional help based on design. Note: not typical style rollover clasp.

Have you tested the Stone? It looks like Chinese or maybe Persian Tourquise or a very good imitation. I say that because of the color as well as the Mark, if turned around 180• the writing looks Arabic or South Asian. (More Arabic.) BWDIK 😕

I have tried cleaning a little more and that was no help. I am definitely clueless on turquoise of any type.

 I annoy KEITH on those....LOL

Hey Sheila, sweet pin! Looks like a glass stone to me, is it evenly shiny on the top?
