It may be plated. Did you scrape the test area before testing?

I found a matching set or 18K white gold earrings last year about a month apart less than 20 feet from each other. One of them had the 750 stamp, the other one did not, it had other things stamped on it but nothing that identified it as gold. Now, I know that's not common practice but it could explain why you found one without a stamp.
