The origin of lab grown diamond?
In 1954, synthetic diamonds were successfully synthesized for the first time. Researchers made a diamond in the laboratory. They imitated the environment where diamonds were formed in nature and applied extremely high temperature and pressure to carbon, thus giving birth to diamonds. The method is called HPHT diamond. Also in the 1950s, another method of manufacturing synthetic diamonds was developed. This is called CVD, which deposits carbon from a carbon-containing gas mixture into diamonds at very low pressure and relatively low temperature.
In 1963, China successfully cultivated the first man-made diamond. In 1971, GE in the United States cultivated gem-level cultivated diamonds for the first time. In 1988, De Beers in the United Kingdom successfully cultivated cultivated diamonds with colorful colors.


How to distinguish LAB GROWN DIAMONDS from NATURAL DIAMONDS?
In the early days, due to the inadequate technology of lab grown diamonds, diamond dealers could distinguish between man-made diamonds and natural diamonds in a very simple way. Because man-made diamonds contain metal crystals remaining in the manufacturing process, strong magnets can be let make man-made diamonds sucked up.However, with the continuous improvement of man-made diamond technology, the original old methods are no longer available. At present, man-made diamonds need special appraisal institutions and appraisal instruments to achieve. Now, only a few laboratories in the world have the ability to distinguish man-made diamonds and natural diamonds. At present, the world’s three major professional jewelry appraisal agencies GIA, IGI and HRD have recognized the status of man-made diamonds. At the same time, the appraisal agency can issue a certificate of identification and grading of cultivated diamonds, and each diamond has a unique code inscription at the diamond waist
