....who doesn't know the size of their diamond(s)?
I know my ring is beautiful, that my FI picked it out specifically for me, and that in itself makes it the most amazing thing to me. I know when he proposed he said something along the lines of it's blah-blah-blah carrot and whatever, but I honestly was so happy that I was not listening to him nor did I care.
Same with my wedding band. We went to the store, found one that looked great with my e-ring, and was pleasantly surprised when she showed us the price and it was WAY under our budget.
I guess I was never one who cared about the size of the rock - but when I see lots of girls comparing or naming the size of their ring - I wonder, how much does the size of the ring matter to them?
