LOVE CREATED DIAMOND currently employs two manufacturing methods: high pressure high temperature (HPHT) and chemical vapor deposition (CVD). These methods enable the production of diamonds with identical chemical composition and crystal structure to natural diamonds. In addition to controlling impurities during the manufacturing process, it is also possible to alter the color of the diamonds through subsequent treatments.
HPHT
HPHT (High Pressure High Temperature) is a major method used in laboratories for diamond manufacturing. In this process, a diamond seed is placed in a metal solvent and placed in a “growth chamber” similar to a pressure cooker.
The temperature is raised to around 1500 degrees Celsius, allowing carbon material to crystallize onto the diamond seed. This diamond growth process requires subjecting the carbon to extreme temperature and pressure conditions, simulating similar conditions to those found deep within the Earth where natural diamonds are formed.
CVD
CVD (Chemical Vapor Deposition) Diamond use diamond chips as seeds to grow. It take place inside a vacuum chamber filled with a hydrogen and carbon-containing gas, such as methane. A source of energy — such as a microwave beam — breaks down the gas molecules, and the carbon atoms diffuse towards the colder, flat diamond seed plates. Crystallization occurs over a period of weeks, and several crystals grow at the same time.
