Web29 de nov. de 2024 · How are artificial diamonds made to look like natural diamonds? Artificial diamonds are made by heating and pressurizing carbon atoms together to create a diamond-like material. To create a diamond-like material, the carbon atoms are heated until they reach a temperature where they form a diamond.
WebThe CVD technique (chemical vapour deposition) starts with a diamond seed crystal (usually a HPHT crystal). This process uses gas in a vacuum chamber and microwaves – together this causes carbon atoms to accumulate on the diamond seed, thus creating a diamond.
