It is one of the types of gemstones known to mankind since ancient times, as it was used as a type of jewelry, and it is used in decoration works. [1]
How diamonds are formed
The pressure and very high temperatures are the main constituent conditions of diamonds. These environmental conditions exist in limited areas 90 miles, or 150 km, below the surface of the earth where the temperature reaches 2000 degrees Fahrenheit, or 1050 degrees Celsius, [2] , so this is enough. By reconfiguring the crystalline carbon called graphite from hexagon to triangular shape, which is diamonds, diamonds come out to the surface of the earth through the sulfur-tubes and lambarite produced from volcanic eruptions. [3] It is worth noting that only one out of two hundred tubes contains high quality pure diamonds. [4]
History of diamonds
In the fourth century B.C. in India, the first diamond was discovered , as it was noticed because of its great difference from volcanic rocks, believing that these are gifts from the gods that will bring health, wealth, and strength. until today. [3]
Diamond uses
The uses of diamonds extend far beyond the manufacture of jewelry and jewelry. It has been used in many areas such as [5] : -
the health
According to a recent study by the University of South Wales, diamond particles that are a thousand times smaller than human hair (Nanodiamonds) are used to help treat cancer by attaching it to chemotherapy, since the cancer cell gets rid of chemotherapy if it reaches it and does not give it the time needed for treatment, But with the addition of particles, it does not have the ability to get rid of diamonds, so the treatment remains inside.
teeth medicine
Diamonds are used in dental boring and drilling tools , as diamond particles are placed on top of tools to enhance their abrasion property.
Industrial applications
Due to the strength and hardness of diamonds, it has become an expensive and effective choice in the industrial tools industry, such as: cutting, polishing, and drilling, and its particles were also used in the oils of some equipment to make it more powerful.
