Gemstones - Abrasive
An abrasive is a substance used to wear away another material through friction. Abrasives are essential tools in gemstone cutting and polishing. They are usually harder than the materials they act upon. Their purpose is to remove, shape, or smooth surfaces. Many gemstones require multiple abrasive stages during processing.
Emery, which consists largely of powdered corundum, is a traditional abrasive. Other important abrasives include diamond powder and carborundum. These materials possess exceptional hardness. Their cutting ability makes them ideal for shaping gemstones. Different abrasives are selected according to the hardness of the stone.
Diamond powder is one of the most effective abrasives available. Because diamond is the hardest known natural substance, it can abrade nearly any gemstone. Diamond abrasives are commonly used in modern lapidary work. They provide efficient cutting and polishing performance. Many precision tools rely on diamond particles.
Abrasives are available in various grades and particle sizes. Coarse abrasives remove material quickly during shaping. Finer abrasives are used to refine surfaces and eliminate scratches. The final polishing stages often involve extremely fine abrasive compounds. This gradual progression creates a smooth and reflective finish.
The use of abrasives is central to gemstone manufacturing. Without them, transforming rough crystals into finished gems would be extremely difficult. Proper abrasive selection improves efficiency and quality. Skilled gem cutters understand how different abrasives perform. Therefore, abrasives remain indispensable in lapidary science and practice.
