I am looking at eternity bands and have found one that is princess cut diamonds, channel set, which I like very much. However, I do not care for the sides of it, to me it looks like a washer, used in plumbing. Then at Asprey I saw a similar ring with brilliants on the sides, is this a style anyone has seen anywhere but Asprey? And does it weaken the ring by having diamonds on the sides? Additionally, white gold vs. platinum???
