I wandered in from All. As a cishet woman I’ve worn my wedding ring on a sterling silver rope chain both times I was pregnant, and I wore my husband’s on the same chain when he was in ICU for a few months and couldn’t wear it. It kept it visible and close to my heart. A silver chain isn’t terribly expensive and can be worn alone when you don’t need it for the ring.
Maybe it was on a plate and he also brought a big napkin, and followed up with a hot wet washcloth. The one that already has a stain.
