Out of these, one of the main specifics that play a major role in enhancing the overall appeal of the center diamond is the diamond ring band. So in case you want to emphasize on your center diamond to the fullest, the best option is to choose a diamond ring with a thin band. Just make sure to keep the band plain, because adding embellishments to a thin band may make it vulnerable to bend or break. Usually, the width of a thin diamond ring band ranges from 2.5 to 3 millimeters. If you were looking for really skinnier diamond engagement ring bands, the thickness would be from 1.5 to 2 mm. One of the main advantages of choosing a diamond ring with a thin band is that it will be comfortable to wear because of its lightweight. Plus, the other settings in a thin band diamond ring will be lightweight too, such as the mounting, the gemstone, the metal setting, etc. Besides, skinnier diamond rings can make your fingers look even more appealing.
