"Rustic Romance" CC Ring vs Other CC Rings

My guess is that Rustic Romance CC rings use different texture space than most of the rings, because that's the reason why there's a clash between eyelashes and glasses/bracelets/rings, depending on which eyelashes you use. If certain eyelash uses the same texture space as lets say, rings, even if they're both in different categories in CAS, they'll clash. And no, it's not possible to increase the texture space, at least for sims 4. It's limited unfortunately, so you just have to choose either one.
