Eternity diamond rings are often gifted in order to mark important milestones in a relationship such as an anniversary or the birth of a child. However, giving these rings as engagement rings is also a good way to express your love and commitment towards your partner. The most common design for a diamond eternity engagement ring features a yellow gold band entirely paved with melee diamonds. There are certain things that you must look for while buying a diamond eternity engagement ring. The first thing is the lifestyle of your partner; make sure that the designs, as well as the settings of the ring, complement her everyday life. For instance, if your beloved leads an active lifestyle, it is better to consider a pronged setting as it is easier to clean it. Otherwise, you can also choose a bezel or channel setting for better safety of the gemstones. Another thing that you must contemplate on while selecting eternity diamond rings is that whether the ring reflects the personality of your partner. If she is all about the latest trends, consider a rose gold eternity band. For simple and refined taste go for the yellow or white gold.
