Tiny Gold Ring - CHECO

I have this tiny gold almost looks rose gold ring. Inside is the mark CHECO and what looks like a star behind it. I'm curious to know any information about that specific hallmark. Those are the only 2 markings there is no purity stamp. From what I know belcher settings were popular in the late 1800s to early 1900s. Any info is appreciated! Thank you!
