I planning on wearing any 2 of those at a time along w/ my solitaire. Then when I don't want to wear my big stone I can leave it in the safe and add another band to it.
I have a "thang" about odd #s, I think everything looks better in 3's.
So one day I could wear the sapphire/diamond band plus the all diamond one w/ my solitaire, next day it could be the yellow/diamond band plus the solitaire, etc. . .
Hopefully over the years DH will continue to buy me a different band once in a while.
