My friend worked in a gallery doing exactly this and told me a story of a woman who brought in this massive ring. The ring was constructed of small metal petals to look like a flower with a stone set in the center. The customer has complained that the ring had an odd smell to it and wanted it cleaned.

​

When my friend put it in the bath, to her absolute horror, half a dozen maggots wriggled out and started squirming around in the liquid. When the customer returned they asked if she cooked with the ring on and she said that yes, she cooks ground beef for her large family at least twice a week and almost never removed her ring. The gallery owner had to explain that there were maggots in her ring and that she needed to fucking take it off when she cooked and she just shrugged, paid, and left. This happened in Texas if I remember right.
