Question about WS mark and turquoise (real or not?)

Hi there - wondering if anyone had any input on these earrings? From what I found so far it looks like Willie Saiz Is the artist perhaps? I’m not very experienced with turquoise either and wondering if anyone thought this could be real or if it looks fake? Thanks!!!

I am not familiar with the hallmark or artist name. A good looking pair of earrings. The stones look like they could be block turquoise (not real). Enjoy wearing them.
