From Wikipedia:
"Bruting is the process whereby two diamonds are set onto spinning axles turning in opposite directions, which are then set to grind against each other to shape each diamond into a round shape. This can also be known as girdling."
A diamond is transformed to a gemstone by several processes: cleaving, bruting, sawing and polishing.
Diamonds are cut by diamond cutters who are trained to plan the cut, execute it, and then cut facets into the stone and finally polish it. You can watch a video, below, and learn more from the Wikipedia link, also below.
Diamonds are mined from the earth, and in the mining process the diamond stones are separated from the other material. Seventy-five to eighty percent of diamonds are graded as industrial diamonds, and sold in bulk as bort to makers of diamond-coated tools and precision instruments. The raw, gem-quality stones are moved to a sorting process, where like stones are grouped, and where larger stones are separated out for special treatment in order to maximize their value. Once a stone reaches the cutting table, it follows a series of steps, including "...planning, cleaving or sawing, bruting, polishing, and final inspection."
