Query: I would give it less than one star if I could

I bought one of these for my mom--Mother's Day present. She loved it. A few months later I learned that a stone had fallen out of it. Too late to return it to Amazon, so I bought her another one. The very same day I gave it to her, the exact same stone had fallen out and was lost. These rings are cute but the fact that the same stone falls out with minimal wear tells me they are not well put together.I have purchased inexpensive rings from Amazon before and never had this problem.
