There are 3 things my boyfriend has memorized about what I want in my engagement ring (we're looking to get engaged fairly soon).
1. The cut - princess
2. The band - white gold (although I would LOVE platinum, who wouldn't?)

3. The size - 8 (I have chubby fingers, my mom told me it's from cracking my knuckles all the time ?)
I don't even care what size it is, as long as the color, cut, and clarity are good and that he took the time to pick it out.
