Diamonds are famous worldwide for their beauty and prestige, but not many people are aware that diamonds have other virtues as well. Since diamonds are the strongest and hardest natural material known to man, they are often used for industrial purposes. Industrial diamonds are valued for their hardness and heat conductivity, while disregarding the four C's that the gemstone industry is based on.

Industrial diamonds are usually inferior to gemstones in clarity, color etc. Contrary to popular belief, diamonds as a whole are not all that rare. Only some 20% of all diamonds mined around the world are used as gemstones, while the rest are used in industry. The line between gem-quality diamonds and industrial diamonds is not absolutely defined: when demand for polished diamonds is high, low-quality diamonds are polished into low-quality or small gemstones instead of being used in the industry.

Diamonds are the perfect material for cutting and grinding tools. Diamond based tools can polish, cut and wear away any kind of material, including other diamonds. Diamonds are used in the industry in drill bits and saws, while diamond powder is used as an abrasive.

In addition to natural diamonds that are deemed unfitting to commercial use, synthetic diamonds also serve as industrial diamonds. A total of 570 million carats of synthetic diamonds are produced annually for industrial use, and 90% of diamond grinding grit are made of synthetic diamonds.

Many Israeli companies, such as Strauss & Co., Ben Gad Yosef and Toolgal provide industrial diamonds and develop diamond cutting tools for turning, boring and burnishing different types of materials.
