You'll want a knife edge ring if you want a wedding ring that looks modern and sleek. With contours crafted out of 18kt white or yellow gold, you get a glitzy sleek shine that is matched by no other and reflects light beautifully. Change it up slightly with a brushed matte or high polished finish and add a personal touch with an engraving up to 15 characters in Script or Helvetica font for an additional fee. This particular band is 4 mm in width and is a nice size ring for men's jewelry.Product Information
