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.
