The HPHT process (high pressure high temperature) has been used to grow diamonds since 1950''s – the pressure and temperatures of the earth are recreated in a lab to crystalize carbon and create a synthetic diamond. The CVD technique (chemical vapour deposition) starts with a diamond seed crystal (usually a HPHT crystal).
HOW DIAMONDS ARE FORMED. Diamonds were formed over 3 billion years ago deep within the Earth''s crust under conditions of intense heat and pressure that cause carbon atoms to crystallise forming diamonds. Diamonds are found at a depth of approx. 150-200km below the surface of the Earth. Here, temperatures average 900 to 1,300 degrees Celsius ...

· The discovery and mining of Canadian diamonds tells the story of the human spirit overcoming nearly insurmountable odds. The Northwest Territories, where most of these diamonds are found, has a subarctic to polar climate. It can be a challenge to survive in the ice and snow of northern Canada, let alone find diamonds.
Once a diamond operation yields ore, the diamonds must be sorted from the other materials. Excavated ore is transported to a processing plant. The kimberlite is first crushed and then processed through the plant, which consists of a series of screens, jigs and scrubbers and a gravity pan or DMS plant to remove lighter particles and create a ...

Once exposed, the ore in the pit is broken up by blasting. A single blast can break approx. 3,000 tonnes of ore. Once the ore is broken, excavators load the ore into haul trucks and transport it to a primary ore crusher where the diamond extracting process begins. The Kimberley Big Hole is …
The ore is enriched using a process called froth flotation. Unwanted material (called gangue) sinks to the bottom and is removed. Roasting This is where the chemical reactions start. The powdered, enriched ore is heated in air between 500°C and 700°C to remove some sulphur and dry the ore…

· Because only diamond can cut diamond, two stones are used to cut each other simultaneously. Computers and lasers have improved the cutting process to a point where it is incredibly accurate. Because it can take up to 8 hours to cut a 1ct diamond, the price of polished stones is high. Rough diamonds are actually a lot less expensive.
· Figure out how much the net cost of that new ring is, subtracting out the value of your trade-in. For example, if your new 1.43 Carat Diamond Ring costs $20,597, and you''re receiving $10,575 for your trade-in, your net cost for the new ring is $10,022.

Diamond is recognized as the only material sampling the very deep mantle to depths exceeding 800 km, as shown in figures 25 and 26. Diamond is less useful at revealing deep carbon flux (the amount of carbon in motion) because it can provide only a small, variably distributed sample that is usually not directly related to its kimberlite host.
