About Us
There are natural and synthetic diamonds. The Earth makes natural diamonds, and people make synthetic diamonds. Diamonds are the hardest natural substance known to man. Diamonds are made of pure carbon, the same chemical element as graphite, fullerene, and coal. But diamonds are very hard and in crystalline form. It is commonly believed that diamonds are formed from coal, but this is not true.
Diamonds are made deep in the Earth where there is an intense amount of pressure and heat. The formation of natural diamonds needs specific conditions. These are exposure of carbon-bearing materials to high pressure, between 45 and 60 kilobars (4.5 and 6 GPa), but at a comparatively low temperature, between about 900 and 1,300 ℃ (1,650 and 2,370 ℃). These conditions are found in two places on Earth: in the lithospheric mantle below relatively stable continental plates, and at the site of a meteorite strike.
People find diamonds where volcanoes were a long time ago. They sometimes find tiny ones at the site of a meteorite strike. Sometimes people find diamonds on the top of the ground. But in places like South Africa, they must dig deep down into a diamond mine to get diamonds. Diamonds were first found in India.
Small synthetic diamonds are made for abrasives. Large synthetic ones are even more expensive to make than to find and dig up, so people don't make large synthetic diamonds.
Since 2011, we have been starting diamond manufacture with jewellery diamond tools. Diamond tools used for jewelry manufacturing, Machine tools, hand tools, Chain tools, inside and outside turning tools, flywheel, CNC diamond tools. Designing, Production, Repair and polishing of all kinds of natural diamond(ND), Synthetic diamond(MCD), PCD and carbide tools used for gold, platinum and silver jewelry making.
