Difference between diamond and natural diamond

The essential difference between diamond and natural diamond lies in their processing form and application field.Diamond is an unprocessed natural mineral, while natural diamond is a gem grade diamond product that has been cut and polished.

Core Differences Analysis

Essential definition.

Diamond: a natural carbon elemental crystal with the chemical formula C, possessing a regular octahedral crystal form and a Mohs hardness of 10, making it the hardest known natural substance. ‌‌

Natural Diamond: A product of diamond that meets gem level standards and has been cut, ground, and polished. It belongs to the processing form of diamond and has both decorative and investment properties. ‌‌‌‌

Differences in processing techniques.

Diamond only requires physical mining and basic screening to preserve its original crystal characteristics. ‌‌Natural Diamonds require professional cutting (such as laser or mechanical cutting), polishing, and symmetry grinding, typically forming 57-58 facets to enhance optical effects.

‌‌Application layering.

Industrial use: About 80% of diamond is used to manufacture cutting tools (such as drill bits), grinding materials, and semiconductor devices, and its value is mainly determined by hardness and thermal conductivity. ‌‌

Jewelry use: Only 20% of gem grade diamonds can be processed into diamonds, and their value needs to be evaluated through the 4C standards (color, clarity, cut, carat). The global annual production of diamonds is about 20 million carats. ‌‌

Key points of extended cognition

Quality screening criteria: Industrial grade diamonds are allowed to contain impurities, while gem grade diamonds require crystal transparency and defect diameters less than 5 microns. ‌‌

Value comparison: Under the same weight, the value of diamonds can reach thousands of times that of industrial diamonds. For example,high-quality diamonds of 1 carat can be sold for over 10000 yuan, while industrial grade diamonds have a unit price of less than 10 yuan. ‌‌

Artificial synthesis technology: Modern chemical vapor deposition (CVD) can produce industrial diamonds in bulk, but the cost of synthesizing gem grade diamonds is still higher than natural mining processes
