Synthetic diamonds are made at about 300deg c but usually in a pressure vessel using microwave radiation and a seeding crystal. The process works by placing a tiny fragment of diamond called a carbon seed into a microwave along with varying amounts of a carbon heavy gas methane is most commonly used. Once found the diamond is put under pressure of 725 000 pounds per square inch. Copper disc embedded with diamond dust sawing a rough diamond. According to live science to make a diamond there is a three step process.
Below ground mining of kimberlite for diamond also requires moving enormous quantities of rock and other material in order to unearth gems but on a much larger scale than alluvial mining. The cleaving process is the part that involves splitting the rough into separate pieces. Geologists believe that the diamonds in all of earth s commercial diamond deposits were formed in the mantle and delivered to the surface by deep source volcanic eruptions. You can make diamond as big or small as you want by growing them in a chemically neutral environment nobel gas nitrogen using co2. The typical cvd diamond creation process goes something like this.

Natural gas is zapped into a plasma of carbon which sticks to each diamond seed thus building a diamond one atom at a time. 1 diamond formation in earth s mantle. These eruptions produce the kimberlite and lamproite pipes that are sought after by diamond prospectors. As you can imagine the journey a rough diamond undergoes from its violent formation process to being mounted on an exquisite setting is a long process and passes through many different channels.

The gas mixture is heated to very high temperatures in the microwave to produce a plasma ball and inside this the gas breaks down and the carbon atoms crystallise and accumulate on the diamond seed causing it to grow. A diamond seed which is a tiny piece of diamond with a repeating pattern of carbon atoms like all diamonds have is placed inside a microwave plasma oven. It is also put under extreme heat of.
