Lab Created Diamonds Description
Lab created diamond is a synthetic diamond grown in the laboratory to simulate the natural diamond growing environment. The methods of synthetic diamond cultivation mainly include HPHT high pressure and high temperature method and CVD chemical vapor deposition method. The incubation time is about half a month to one month. Growing diamonds have the same physical, chemical and optical properties as natural diamonds. They are simple to produce, environmentally friendly (Frost&Sullivan reports that the harmful carbon emissions from mining diamonds are 57,000 grams per carat, while the harmful carbon emissions from growing diamonds are only 0.028 grams per carat) and cheap (about 30% of the natural diamonds, Positioning light luxury), style and other advantages.
The earliest lab created diamond was created in 1952. After 50 to 60 years of development, it has only received extensive attention in the industry in recent years. Authoritative jewelry appraisal institutions at home and abroad, such as NGTC and IGI, have released relevant standard documents in 2019-2020 to clarify the concept of lab created diamond, and have opened lab created diamond testing business to the market. And can issue special test certificate or grading report, etc., to provide healthy guidance for the standard development of the industry.

Characteristics Of Lab Created Diamonds
It only takes a few weeks in the laboratory to achieve the same physical, chemical and optical properties as natural diamonds. Cultured diamonds are synthetic diamonds that are grown in the laboratory under conditions that mimic natural diamonds. Unlike natural diamonds, which take millions or even billions of years to grow deep inside the Earth, it usually only takes a few weeks to grow a diamond in a lab. The formation temperature of natural diamond crystal and laboratory grown diamond is almost the same, both in chemical composition, physical properties are completely the same, from the naked eye is unable to distinguish between the two.

From a scientific point of view, cultivated diamonds are exactly the same as natural diamonds, the only difference being where they are formed.
