I have earrings that have the abbreviation "STC" on them, with a tiny numeric 4, and sterling screw on type backings. They have green and white stones, and I can't I.D the maker through any site. Any ideas?


Hi, I am not familiar with that maker's mark. If it's newer jewelry, the websites may not have been updated to show this mark. The only thing I can suggest is to go to either the Online Encyclopedia of Silver website, or the Illusion Jewels website. They have pretty extensive lists of makers. I don't know what the "4" is for, either.
