Most of us think of diamonds as gems used in jewelry; but these sparkling stones are actually only a small percentage of the world’s diamonds mined. Actually about 80% of the world’s diamonds are used in industry (known as industrial diamonds).
What are 80% of all mined diamonds used for?
While most people associate diamonds with diamond jewellery, around 80% of mined diamonds are used for the industrial purposes of cutting, drilling, grinding and polishing.
Are diamonds used in industry?
Because diamonds are very hard (ten on the Mohs scale), they are often used as an abrasive. Most industrial diamonds are used for that purpose. Small particles of diamond are embedded in saw blades, drill bits, and grinding wheels. These tools are then used for cutting, drilling, or grinding hard materials.
What percentage of diamonds are used for jewelry?
Diamonds are best known as gemstones, even though only about 20% of the world’s production by weight is used for jewellery. The other 80%, known as bort, is used in industrial and research applications where the unique properties of diamonds are required.
What is the most important use for diamonds?
The most common uses for diamonds outside of fine jewelry are for industrial applications. Because diamonds are so strong (scoring a 10 on the Mohs Hardness Scale), they are extremely effective at polishing, cutting, and drilling.
Why is the diamond industry bad?
Environment. Due to poor planning and weak regulation, diamond mining has caused environmental devastation, severely damaging the land and water. This irresponsible mining has caused soil erosion and deforestation, and has forced local communities to relocate.
What are 5 uses of diamond?

How big are industrial diamonds?
Industrial grade diamonds can be grown in excess of 150 carats. Different manufacturing processes have unique challenges barriers to creating later gem quality diamonds.
What is industrial grade diamond?
industrial diamond, any diamond that is designated for industrial use, principally as a cutting tool or abrasive. In general, industrial diamonds are too badly flawed, irregularly shaped, poorly coloured, or small to be of value as gems, but they are of vital importance in the modern metalworking and mining industries.
Why are industrial diamonds cheap?
Synthetic diamonds are formed by high-pressure, high-temperature (HPHT) technology or by Chemical Vapor Deposition (CVD). … According to the Gemological Institute of America (GIA), most synthetic diamond producers are shifting to the CVD process because of its lower cost.
What is the current market value of diamonds?
|Weight Range||Avg. Price/Carat|
|0.51 to 0.99 ct.||$3,504|
|1.00 to 1.49 ct.||$6,157|
|1.50 to 1.99 ct.||$8,134|
|2.00 to 2.99 ct.||$10,893|
What company sells the most diamonds?
The top three companies – Alrosa from Russia, De Beers from Luxembourg, and British-Australian Rio Tinto – account for more than 60 percent of global diamond mine production. Mined diamonds are mostly processed in and sold via the major global diamond centers: Antwerp, Dubai, New York, Hong Kong, Mumbai, and Tel-Aviv.
Are diamonds actually worthless?
Diamonds are intrinsically worthless: Former De Beers chairman (and billionaire) Nicky Oppenheimer once succinctly explained, “diamonds are intrinsically worthless.” Diamonds aren’t forever: They actually decay, faster than most rocks.
Can diamond conduct electricity Why?
Diamond is a form of carbon in which each carbon atom is joined to four other carbon atoms, forming a giant covalent structure. As a result, diamond is very hard and has a high melting point. … It does not conduct electricity as there are no delocalised electrons in the structure.
What property of diamond makes it suitable for cutting?
The rigid network of carbon atoms, held together by strong covalent bonds, makes diamond very hard. This makes it useful for cutting tools, such as diamond-tipped glass cutters and oil rig drills. Like silica, diamond has a very high melting point and it does not conduct electricity.
What country is the largest producer of diamonds?
The largest diamond producing country in 2020 was Russia, and secondly Australia. In that year Australia produced about 12 million carats of diamonds. The total global production of rough diamonds amounted to 142 million carats in 2019.
