From a reader…
I have a sterling silver ring from a private vow I made a number of years ago. My spiritual director who witnessed my vow blessed my ring using the Blessing for any object from the Roman Ritual. Over the years it has become scratched and lost its shininess, so I was going to take it in to the jeweller to get polished and possibly plated with rhodium. Would doing this cause my ring to lose its blessing and require re-blessing? (Supposedly getting a chalice re-plated inside requires it to be consecrated again, which is where my thoughts on this are coming from).
You mention the case of the chalice. While some authors are divided, the strong consensus is that, if you gild the cup again, then – yes – the chalice must be reconsecrated before use. I know about “simply use the chalice and it will be consecrated again” blah blah. We are not minimalists. Our objects for worship are important. We are our rites. Let’s be more of who we are rather than less.
In the case of your ring, sure… have it plated. In that case, you could have it blessed again. But the blessing of that ring isn’t quite the same as the consecration of a chalice. It not hurt anything to bless the ring again. Necessary? Probably not.
On the other hand, that ring has been through lots of experiences with you and it shows wear just like you do. Spouses show wear to each other (and cause the wear) and they stick it out… sometimes without facelifts, if you get my drift.
