Due to the three major factors of rare production, beautiful appearance and durability of diamonds, due to the marketing of some jewelers in the last century, diamonds have become a gem that people are flocking to, and their prices have risen sharply, making them the number one gemstone. . The slogan "A diamond is forever, a diamond lasts forever" has also set off a diamond craze in our country. For a period of time, many brides wore diamond rings.
Due to the huge sales value of diamonds and its simple chemical composition, many scientists began to think about how to synthesize diamonds. After years of research, scientists finally synthesized diamonds in 1953, but it was limited. Due to the technology at that time, synthetic diamonds could not reach gem level and were rarely used in jewelry and mostly in industry.
Laboratory-synthesized diamonds are also divided into HPHT diamonds and CVD diamonds, which represent their processing methods: High-Pressure High-Temperature and Chemical Vapor Deposition.
For a long time, the technology of artificial diamonds did not make great progress. It was not until 2010 that Dr. Meng Yufei synthesized the largest colorless cut CVD diamond in the world at that time, weighing 2.3 carats. , Since then, the technology of synthetic diamonds has developed to a new stage, which has also brought huge shocks to the diamond market.
There is no quality difference between lab-created diamonds and natural diamonds. On the contrary, they are superior in quality. They are indistinguishable from appearance. Even professional appraisers must use professional appraisers. Instruments can make the difference.
The application of laboratory-grown artificial diamonds in jewelry is inevitable. Although some established diamond jewelers still deliberately exaggerate the value of natural diamonds in an attempt to artificially distinguish the value of the two. But in 2018, the U.S. Federal Trade Commission canceled the distinction between natural diamonds and man-made diamonds and unified them as diamonds.
