HPHT Lab Grown Diamonds Description
Lab Grown Diamonds, known as synthetic diamonds. At present, there are two methods of artificial cultivation of diamonds in the world: high temperature and high pressure method and chemical vapor deposition method. These two kinds of diamond production methods are different, the products are the same, known as artificial cultivation diamond.
Synthetic diamonds are structurally and chemically matched with what we know as diamonds, which are naturally formed on earth. Although natural diamonds are formed over billions of years, laboratory grown diamonds can be made in a few weeks.
Synthetic diamonds can be made into different colors, which do exist in nature, but are very rare. The only person who can tell the difference between man-made diamonds and diamonds that took billions of years to form naturally is an expert who can use equipment to analyze the subtle differences of trace elements in the formation of diamonds and crystals.
