If you have an engagement ring, think about how it will look alongside a wedding ring. The more features the two share, the more they'll complement one another. Matching the materials, as well as the profiles is a good place to start. If your engagement ring doesn't have straight sides, a fitted wedding band will allow the two to sit comfortably together, minimising wear caused by them rubbing against one another. Dimensions too are key to achieving a unified look. A tenth of a millimetre, more or less, in width or depth, can make all the difference. On the practical side, before you make your final purchase, consider whether it's suitable for the treatment it'll get. Someone with a manual job or with an active lifestyle needs a ring that is robust and hardwearing. Go for a tough material and perhaps also choose a surface like a hammered finish that will help to disguise any knocks and dents you put into it. Remember though, it's quite possible that your ideal ring doesn't exist, so if you opt for a bespoke ring, you'll be able to get involved in the design process and your ring can be made just how you want it.
