We didn't know about silicone rings, but turns out to be what works best for us.
The white ring, that glows a bit like mother-of-pearl, is perfect as a low-budget wedding ring.
Holds its color and glow so far...

I bought two saferingz, the first one was a little tight, so I ordered a size up. I ordered the blue and I like them but the two rings, ordered just a couple of weeks apart, are not the same shade of blue, the second one is lighter and slightly purplish. My wife now wears the smaller one on her middle finger. I any case, they are inexpensive and if you get the correct size, are comfortable.

Gold colored in size 11. I'm much closer to a 10.5 so it's a bit loose (if my hands are soapy/wet from washing it will slip off easily, I found it on the kitchen for once without noticing it had fallen off). I didn't want to get something too small, as I bought this primarily to play hand drums where my hands swell from drumming. It's more comfortable than my actual ring, but I just need to be mindful when I wash my hands. Something to consider if you have trouble remembering that type of thing and are in-between sizes. With playing, the ring gets a literal beating, and it currently has no wear signs at all. At least 20 hours of play time so far.
