It's a rock many women wear for the rest of their lives - a reason enough to think well before you buy it.
Size does matter in this case, but more than size it is about selecting the right cut & color for your love, showing her that you know her personality.

Asking her or allowing to chose is a great way to buy one as well, but let's not forget the romance ... seeing her surprised and happy face , eyes reflecting the shine of a diamond is one of the moments you will remember forever. Take her to few jewelry shop, buy her nice piece and while doing that see what kind of rings she prefers - that way you will not risk giving her ring that she will dislike but carry for life, and on the other side you will keep romance..
