HAFR AL-BATEN: It’s the most important rule a man needs to know about buying a ring for his wife: knowing the right size. The second rule in ring buying: Don’t force a ring that’s too small onto the finger; it’s not romantic, and it can cause considerable discomfort. According to a report in a local daily on Saturday, the Civil Defense had to be called in to cut a ring off the finger of a woman who experience great pain over a number of days after her well intentioned hubby put a size-deficient ring on her finger that could not be removed, even at the emergency room. There’s a third rule to all of this: If you’re going to foolishly estimate ring size, it’s better to guess in the favor of a larger ring diameter so it can at least be removed easily.
