Lab-grown diamonds are just what they sound like. They are diamonds that are grown inside a laboratory using pure carbon in a process that simulates what happens in nature but just speeds up the process by a few thousand years.
Inside a laboratory in Singapore, workers inspect and select a diamond seed. Then dozens of seeds are placed inside the chamber of a diamond greenhouse. Using a scientific method called microwave plasma chemical vapour deposition, a plasma ball made of hydrogen is created inside the chamber. Methane, which is a carbon source, is added. The carbon mix rains down on the diamond seeds, layer by layer, creating a rough diamond that is cut and polished. The process takes about 10 to 12 weeks.
Good said the lab-grown diamonds simply offer consumers another choice and young buyers like a product they feel is eco-friendly and non-conflict.
