Natural diamond rough refers to unprocessed diamonds mined from deep underground.
Over billions of years, deep beneath the Earth's surface, diamonds with a crystalline structure are formed from rocks and minerals in high-temperature, high-pressure environments. Their unique beauty is derived from their crystal structure, and they exhibit a natural brilliance even in their unprocessed state. The difficulty in mining them from deep underground adds to their rarity. Additionally, diamonds are one of the Earth's hardest substances, boasting excellent wear resistance.
The primary uses of natural diamond rough are as follows:
Due to its exceptional hardness, natural diamond rough finds extensive use in industrial applications. Diamond abrasive stones and cutting tools, renowned for their high wear resistance, are employed in various industries. Moreover, diamonds may be used in high-frequency electronic components and sensors.
When used in jewelry such as rings, necklaces, and bracelets, natural diamond rough is often custom-made for special occasions and commemorative gifts. Cutting and polishing natural diamonds enhance their brilliance and beauty.
Some investors, considering rarity and value retention, choose natural diamonds as an investment. The diamond market is stable, and long-term value appreciation is anticipated. However, caution is advised due to the highly specialized nature of the diamond market.
The formation and characteristics of natural diamond rough are related to specific physical and chemical conditions deep beneath the Earth's surface. Diamonds, a form of carbon, are created through the crystallization of carbon atoms under specific conditions.
Typically formed at depths of over 150 km beneath the Earth's surface, the conditions involve high temperatures of approximately 1,200 to 1,300°C and high pressures ranging from 0.725 to 0.9 MPa. Under these extreme conditions, carbon atoms can adopt the diamond crystal structure.
Diamond crystals grow within rocks and minerals underground. This process spans billions of years, gradually forming rough diamonds. Found alongside other minerals and rocks, their rarity contributes to their high value.
Natural diamonds are optically superior, and highly valued as gemstones due to their brilliance and pronounced dispersion of light. Additionally, their exceptional wear resistance and hardness make them widely used in industrial products such as abrasive stones.
The following outlines how to choose natural diamond rough for industrial purposes.
As diamonds are extremely hard, their suitability for applications like cutting, polishing, and grinding is paramount in industrial use. Therefore, hardness and thermal conductivity are crucial selection criteria.
Diamonds have the highest hardness on the Mohs hardness scale among natural substances. The Mohs hardness scale rates the hardness of materials on a scale from 0 to 10, with 0 being the softest and 10 being the hardest. With a hardness of 10, diamonds are highly durable, making them suitable for cutting tools, drill bits, polishing wheels, wire saws, and other industrial tools.
Diamonds possess extremely high thermal conductivity. This makes them suitable for use in high-temperature environments for cutting and polishing or as cooling materials. For instance, when cutting high-temperature metals or ceramics, the rapid heat dissipation of diamonds helps prevent overheating and reduces material degradation.
