Not trying to be mean, but can I ask why you'd be interested in such a thing, since they only call treasure goblins and not rainbow gobs?
Also, are you certain there is such a thing as a socketed legacy puzzle ring? My guess would have been no, but I won't claim that I know that sockets were not one of the possible stats on the legacy ones.
I'm just interested to know why people want certain things sometimes, in case it turns out to be something I want to do as well.
