Few things are better than colorful diamond rings to mark a beautiful milestone in your relationship. Luckily, there are many amazing designs for colorful diamond rings.     A colorful halo diamond engagement ring is one of the best options for almost any bride. In this design, a diamond will be encircled by a halo of colored diamonds or other gemstones. This will also contribute to better highlighting your main gemstone in the ring. Else, you can use a colorful stone at the center and surround it with colorless diamonds. Another trending option for colorful diamond rings is a multi-colored band. This is a relatively more affordable option as well. Here, a 22k yellow gold band is paved with multi-colored stones such as emerald, ruby, sapphire, diamond, etc. This type of diamond ring is ideal as an anniversary gift. For an elegant appeal with a stylish flair, you can choose a three stone diamond engagement ring. For instance, consider a ring where a colorless diamond is flanked with a ruby stone on either side or vice versa.
