Diamond cutting is embellishing a plain medal or pin-badge, commonly brass or copper but can be gold or silver, with a brightly cut, engraved pattern using a diamond tipped tool.
Diamond cut is used to carve the medal's perimeter with a diamond. Ordering this feature adds to your medal's enrichment. You can choose between several types of cuts which are shown to you in the pictures. If your medal is double-sided think about which side you want to have this effect applied, both sides however can be diamond cut.
