Well made and a good finish to it. Unfortunately I can't tell you how well it stands up to time because one of my cats took it away from me when I had it off while taking a shower and I'm not sure where it is.

So, a possible drawback to silicone rings, because my cats have never taken normal jewelry.

That said, if you've not tried a silicone ring, they're super comfortable. I would order another right now, but that thing is in the house somewhere.
