I bought one n April 2021. I initially bought the rose gold version with the 1 diamond but then didn't like how it would rotate away from the top view. So I returned it and bought the version with 8 diamonds. My ideal version would be one with 4 diamonds so that you then also had 4 with the screw motif intact, although I do like that it mirrors the 8 diamonds in my DBTY bracelet.
Attached are pictures of both versions. I find Cartier's rose gold to be more of a softer rose gold, almost like a peach gold. Unless looking at it right next to a yellow gold item it can be hard to tell it's rose gold. I wear it all the time but not to sleep. I have not had it polished by Cartier so it's not as shiny as it was when new but still looks great.
I have had the wedding band version in white gold since 2015 and bought the wider regular love ring in rose gold maybe 2-3 years ago. I love Cartier rose gold, like the above poster said it's very soft in color. Neither of mine have diamonds, just the plain ones.
