A bruted diamond girdle refers to the technique used in the finishing process of a diamond, specifically around the diamond’s outer edge, known as the girdle. The term “bruted” comes from the method of shaping and polishing the girdle using a rotating wheel or tool to smooth out any roughness, creating a rounded, slightly frosted surface.
Bruting is often one of the first steps in diamond cutting and involves shaping the girdle into a uniform form, helping to define the diamond’s proportions. The girdle itself is an important feature because it serves as the boundary between the crown (top) and pavilion (bottom) of the diamond.
When a diamond is bruted, the girdle typically has a polished or frosted finish, depending on the diamond cutter’s technique. A bruted girdle is often seen in diamonds that are of higher quality, as it helps ensure the symmetry and overall aesthetic appeal of the finished stone.
The bruted girdle may or may not show additional markings, such as laser inscriptions, which are commonly used for identification purposes.
