Because of the rarity and high value of diamonds, it is not surprising that some people go to great lengths to replicate their beauty. In recent years, lab grown diamonds (i.e. synthetic diamonds) have become more common and the process more complex and difficult to distinguish.
l Production of lab grown diamonds：
l Difference from natural diamond：
l The meaning of diamonds：
A lab grown diamond is a diamond produced by technical means, rather than a natural diamond formed during geological changes. There is no difference in chemical composition, crystal structure, optical properties, or physical characteristics between lab created and natural diamonds. Most lab grown diamonds can be classified as either HPHT (High Temperature High Pressure) diamonds or CVD (Chemical Vapor Deposition) diamonds, depending on their manufacturing method. HPHT diamonds and CVD diamonds are almost identical to natural diamonds, and the differences between them can only be determined by gemological laboratory analysis.
To the naked eye, a lab grown diamond and a natural diamond may look the same.
Although lab grown diamonds represent a small percentage of the current jewelry market, their popularity is increasing and identification is becoming more difficult. The GIA has been at the forefront of the challenging field of diamond appraisal, issuing unique lab grown diamond appraisal certificates to prevent consumers from being misled.
Both lab grown and natural diamonds are the exact same carbon and have the same physical, chemical, and optical properties. Therefore, lab grown diamonds are just as genuine as natural diamonds.
The main difference between the two is that lab grown diamonds are crystallized in a laboratory; natural diamonds are crystallized in their natural environment. Because lab grown diamonds have the same characteristics as natural diamonds, there is very little wear and tear.
"A diamond is forever, a diamond lasts forever." This phrase does not only refer to natural diamonds, but lab grown diamonds are also applicable.
Diamonds have a wealth of meanings, symbolizing romance, love, money, and power. But for many people, a good quality diamond is the main thing. These colorful stones attract people to spend thousands or more on them. But if cheaper diamonds were available, would you choose them?
In the last decade, laboratory diamond technology has improved considerably to achieve the same quality as mined diamonds. Natural diamonds and laboratory diamonds are almost identical in that they are composed of pure carbon and have a very similar crystal structure. The differences can only be detected with specific instruments.
In nature, diamonds are formed on the surface of the earth 200 kilometers below and are lifted to the surface of a crater after tens of billions of years due to the intense heat and pressure created by the movement of the earth's crust.
In contrast, modern laboratory diamonds are created in the laboratory using two methods HPHT (High Pressure High Temperature) or CVD (Chemical Vapor Deposition). Regardless of the method used to create the diamond, if done properly, it is indistinguishable to the naked eye and can only be detected with specific laboratory instruments.
In addition to their use as jewelry, diamonds are widely used in industry, science, military, and other fields. Because of the wide range of uses for diamonds, people have chosen to make high quality diamonds in the laboratory. And as technology continues to improve, the quality of diamonds created in laboratories continues to improve, making them a top notch alternative to natural diamonds.
