Lab Grown Diamonds
LAB GROWN DIAMONDS
The HPHT method simply mimics the environment deep within the Earth in order to break and reassemble carbon atoms from a rich carbon source (such as Graphite) into the unique atomic structure that form a diamond. The cost of this method is high and requires special equipment to reach temperatures of 1300-1600 Celsius and pressures over 870,000 pounds per square inch! The growth time takes roughly a week. It is important to note that HPHT lab grown diamonds are NOT the same as HPHT natural diamonds. Please click here to read more about HPHT natural diamonds.
The CVD method uses a multi-phase diamond growth process. A tiny diamond seed is placed within the chamber. A hydrocarbon vapor is then dispensed into the vacuumed chamber at a temperature between 900-1200 Celsius. Once the conditions are met, a microwave beam causes the carbon atoms in the vapor to precipitate onto the diamond seed and grow the diamond crystal. Every few days the process is halted to allow the removal of carbon atoms that have not crystalized into a diamond (normally black or brown growths on the surface of the diamond). Once removed, the diamond crystals are inserted back into the chamber and the process is repeated. This process takes place for 3-4 weeks until the desired size is achieved.
Lab Grown diamonds are a great choice for those looking for a more affordable diamond. With so many options to choose from, we understand that the decision can be confusing! Let us help you make the best decision, so you can decide what diamond is best for you.
