I thought I had listed this one here, but evidently not. $300 for PS members. It's 3mm, a weighty 3.8grams and very comfortable in that rounded comfort fit.
Bump again! This is such a perfectly shaped rounded band and it's not flimsy at 3.8 g (I find some of these bands are super lightweight) It was classified as yellow gold but has a rosy tinge.
Oh, thank you for letting me know. I must have deleted the original when I reduced the price. It says 280 on LT, but 250 for PS. I hope this link works
