There are certain things that you must keep in mind while choosing platinum diamond wedding rings for women in order to be sure that you are making the right choice. The first thing you must consider is the purity of the platinum metal; only the purest form of platinum rings will exhibit its supreme qualities. Note that the purest form of a platinum ring will have 95% platinum metal and 5% alloy metal like cobalt, palladium, iridium, etc. If this type of wedding rings is too expensive for you, choose a ring that is 90% pure. Next, think about the diamond ring setting that your better half would prefer. If she is more into fashion and trends, stylish options like prong setting or tension setting will be perfect for her. In this case, a major portion of the gemstone will be exposed, and hence, it must be secured well in order to protect it from external damages. So, make sure that you choose the purest platinum setting to hold the gemstones in place. Additionally, keep her lifestyle as well in mind while choosing a setting for her.
