Diamond Saw
Diamonds must be cut using another diamond because diamonds are one of the hardest substances on earth. A diamond saw is a thin phospher bronze blade. The cutting agent is diamond saw dust that the blade picks up as it cuts into the diamond. To get a start, the blade knocks against the diamond and collects dust and the dust then is used to cut the diamond. The process is lengthy, taking up to several hours for a 1-carat diamond. Before diamonds are cut, a planner decides where the cuts should be made to make the most profitable diamonds based on size and clarity of the original diamond.
Bruting
The round outlines on a diamond come from the bruting process. Bruting creates the basic outline of the diamond, which is polished later to add facets. During bruting, a diamond is spun on a lathe, a tool that rotates an items for sanding, polishing or cutting. While the diamond is rotated, another diamond spins against it, forming the rounded outline. Bruting is also called rounding.
Polishing Wheel
After the basic conical shape is made, a polisher further refines the diamond on a polishing wheel. This is the last stage of the diamond manufacturing process. First in the polishing stage is blocking. In blocking, the basic symmetrical design of the diamond is determined. The initial 17 or 18 facets are made. The person who cuts these facets is known as a "blocker." The diamond is polished by cutting. The gem is placed on dop stick and rubbed against either moving cast iron disk, Some diamonds are further polished by a "brillianter." In this stage up to 40 additional cuts are made. The number of facets added during these two stages determines the brilliance and shine of the diamond, which makes a huge difference in the diamond's value.
