Lab Grown Diamonds Description
The development of artificial cultivation technology has provided more possibilities for life. Lab grown diamonds has overturned the traditional positioning of jewelry, allowing consumers to buy larger and better-cut diamonds for the same budget. The flexibility to tailor size, shape, color and other visual features to your own needs has made Grow Diamonds a hit with a new generation of consumers. At the end of the 18th century, Lavoisier, a French chemist, discovered that diamond is a single crystal composed of carbon elements formed under high pressure and high temperature conditions in the deep earth, which laid the theoretical foundation for the subsequent cultivation of diamond technology.
In 1952, the United States federal silicon carbide company scientists - William eversau use Chemical Vapor Deposition method (Chemical Vapor Deposition, referred to as CVD), let contain carbon gas continuously deposited on the diamond seed crystal, gradually accumulated hardening to form diamonds.
In 1954, ge super pressure project led by Dr Hall, head of the team, in cultivating diamond technology breakthrough, invented the "method of high temperature and high pressure synthesis of diamond" (High Pressure High Temperature, HPHT).

From a scientific point of view, cultivated diamonds are exactly the same as natural diamonds, the only difference being where they are formed.
Advantage 1: the cultivation of diamond cost-effective advantage is significant
Cultivation of diamond cost-effective advantages, shorter formation time. In terms of price, lab grown diamonds in terms of color, size, clarity and natural diamond, but the same size and grade of cultivating the market price of the diamond is half that of natural diamond or less, according to bain in 2019, the global diamond industry report, 2016 about 80% of the natural diamond, diamond retail price From 2017 to 2020, this proportion will be reduced to 65%, 50%, 50% and 35%, respectively. Lower production costs and retail prices provide strong support for lab grown diamonds to further expand market share. In terms of production time, lab grown diamonds can be produced in just a few weeks, while natural diamonds take hundreds of millions of years to form.
Advantage 2: cultivate diamond in line with the trend of environmental protection, sustainable development
Natural diamond deposits are limited, and global diamond production has declined every year since 2017. Natural diamond mineral resources are non-renewable resources, the reserves of natural diamond mineral resources are very limited in the world, and diamond mining rights are highly monopolized by several major diamond miners. The natural diamond primary ores are mainly distributed in South Africa, Zaire, Botswana, Russia, Australia and other countries. The mineral reserves are not high, the mining cost is high, and mining is difficult.
Carat 1
The size of a diamond is proportional to its carat weight. When rough diamonds are cut and polished into finished diamonds, up to 2/3 of the total carat weight may be lost. Since larger rough gems of high quality are found less frequently than smaller rough gems of high quality, a single two carat diamond will be more expensive than two one-carat diamonds of the same quality.
Color H
A diamond’s color is an important element of its quality. In a white diamond, the less body color present, the greater the value of the diamond. The GIA grades diamonds on a scale of D (colorless) to Z (noticeable color).
The predominant color you see in a diamond is yellow, which is caused by the trace element nitrogen.
Clarity SI1
Clarity refers to the presence of imperfections, flaws and blemishes inside or on the surface of a diamond.
The GIA grades diamond clarity under 10X magnification on a scale that ranges from Flawless (FL) to I2-3 (Included). Diamonds with the least amount of flaws having the highest clarity grading.
A diamond’s clarity has a significant impact on its value.
Cut Very Good
The cut of a diamond influences how effectively it reflects light. Well-cut diamonds appear fiery and brilliant and allow light to enter the stone and be reflected around the facets before exiting the stone through the top. Poorly-cut diamonds can appear lifeless and dark, despite their clarity or color grade.
Not only do well-cut diamonds appear more brilliant, they also tend to appear larger than other diamonds of the same carat weight.
