![]() 5. Ring SIZE - be discreteThe issue of working out your partner's ring size can be a big one, particularly if they don't wear many rings. There are a few ways to obtain a ring size including measuring another ring worn on the right-hand ring finger, purchase a ring sizer, ask a friend to help get the details, or measure the finger but note the knuckle may be the widest point of the finger. Australian ring sizes are scaled in letters from A-Z and also include half sizes; the most common sizes for females are between and I and O. Not to worry if you don't get it right as most precious metal rings (platinum, gold and silver) can easily be resized up or down, but be sure to check with your jeweller when you purchase, that it can be resized and how much this will cost. |
