HPHT Lab Grown Diamonds Description
1. What is lab grown diamond?
Lab-grown diamonds are grown in the laboratory. People use advanced equipment to simulate the environment in which natural diamonds are formed. Diamond crystals are used as seeds to induce the growth of diamond crystals. The physical and chemical properties of man-made diamonds are exactly the same as natural diamonds. With the development of science and technology, the purity and color of man-made diamonds are getting higher and higher. At present, high-quality man-made diamonds are mainly used in jewelry.
2. What is the difference between laboratory grown diamonds and simulated diamonds?
Unlike laboratory grown diamonds, simulated diamonds are not real diamonds. Although the shape of simulated diamond is similar to real diamond, it is made of seed materials such as glass or cubic zirconia. This makes it impossible for simulated diamonds such as carborundum to possess the hardness and optical properties of laboratory grown diamonds. As time goes on, they are more likely to wear out and lose their luster.
3. Can we distinguish between laboratory grown diamonds and natural diamonds?
Yes it is. However, only diamond professionals can identify the difference between laboratory grown diamonds and natural diamonds by using professional diamond identification equipment.
4. Is the price of laboratory grown diamonds different from the price of natural diamonds?
The price of natural diamonds is determined by the unique characteristics and rarity of the diamond, while the price of laboratory-grown diamonds is determined by the number of carats. In addition, the advantage of laboratory-grown diamonds is that they are much cheaper than natural diamonds because their production is not restricted.

HPHT Lab Grown Diamonds Introduction
Natural diamonds are created by nature and are the result of high temperature and pressure formed over billions of years. The Rough Lab Grown Diamonds are produced in the laboratory, usually in a few weeks. The chemical difference between the two is same.
So how do you distinguish between Rough Lab Grown Diamonds and natural diamonds?
There is no obvious difference between the Rough Lab Grown Diamonds and natural diamonds. Even professional gemologists need special equipment to identify them. By zooming in, professionals will be able to discern subtle contrasts in diamond inclusions grown and mined in the laboratory.
