What is Lab-Grown Diamonds

Artificially cultivated(as CVD) diamonds, also known as laboratory-grown diamonds, it takes a flake natural or lab-grown diamond loose stone as the “seed”, using high-purity methane, hydrogen and other gases to assist, in the microwave plasma generator, in a high temperature and low pressure way, to form carbon ions, these plasma will be like dust, little by little deposited on the “seed” diamond crystallization, the seed wafer will slowly grow and grow larger layer by layer.

Natural vs Lab-grown diamonds and Price

After the diamond “seeds” grow, through cutting, polishing and other processing processes, artificial diamonds can be cultivated. Like natural diamonds in terms of chemical and physical properties, it is also a real diamond, and it only takes half a month to cultivate a diamond of about 1 carat.

The growth of a natural diamond takes millions or even hundreds of millions of years. But if in the laboratory, it only takes 5-7 days for a large diamond of one carat to grow. Of course, the higher the carat number, the longer it takes to grow.

“Diamonds are forever, one piece will last forever”, this slogan is widely circulated all over the world, and it also gives diamonds a special meaning. However, with the development of technology and the emergence of artificially grown diamonds, diamonds may also be redefined. “Some internationally renowned jewelry brands and luxury brands have begun to use lab-grown diamonds in their products.”

The price of lab-grown diamonds is about 20%-30% of that of natural diamonds. In other words, if you can accept lab-grown diamonds as your wearing gemstones, then you have the possibility of “diamond freedom”.

Lab-grown diamonds are also certified

Many people still want to ask, is there an official certification for lab-grown diamonds? International authoritative jewelry testing institutions GIA, IGI, and HRD will also issue corresponding certificates in accordance with natural diamond standards. The difference is that “Laboratory grown diamond” will be specially marked on their certificates, which means laboratory grown diamonds.

Different from imitation diamonds moissanite and zircon (cubic zirconia), lab-grown diamonds and natural diamonds can not be identified by the naked eye or simple equipment, and professional instruments need to be used to comprehensively evaluate the characteristics of lab-grown diamonds through spectroscopy, crystal growth lines, cathodoluminescence and other methods, while cubic zirconia and moissanite are similar to diamonds in appearance and optical characteristics, but they differ greatly in physical properties and chemical composition, and are pseudo-diamonds.

China is the world’s largest producer of lab-grown diamonds, accounting for more than 40% of rough diamond production and 90% of global HTHP lab-grown diamond production capacity. Due to geographical restrictions, the upstream mining of natural diamonds has long been monopolized by foreign countries, according to De Beers statistics, the world’s main producers of natural rough diamonds are Russia, Botswana, Canada, etc., China’s natural diamond production is small, but China occupies nearly half of the upstream share of the lab-grown diamond industry chain.

What is moissanite

As a natural element mineral, moissanite is the second hardest gem in the world. The natural moissanite is a meteorite from outer space. In 1894, a French Nobel Prize winner, Dr. Henri Moissan, found a kind of carbon silicon bound particle from the meteorite falling in Arizona, the United States, which was extremely bright, and the outside of the material was very similar to diamonds, but there was no such component on the earth, so scientists began to develop it. In 1905, to show respect for Dr. Henri Moissan, this newly discovered gem was named moissanite. The stone is an artificial gem.

The difference between lab-grown diamonds and moissanite

Although lab-grown diamonds are produced in the laboratory, their properties are exactly the same as natural diamonds, while moissanite is completely different. Mainly manifested in the following aspects:
·Crystal structure: Cultivated diamond “cube”, Moissanite “hexagonal”
Chemical structure: lab-grown diamond “c”, moissanite “sic”
・Dispersion rate: Cultivated diamond “0.044”, Moissanite “0.104”
· Refractive index: Cultivated diamond “2.42”, Moissanite “2.65”
Density: Cultivated Diamond “3.52”, Moissanite “3.21”
Hardness: Lab-grown diamond “10”, moissanite “9.25”
Taking natural diamonds as a reference, cultivated diamonds are better than moissanite, the main reason is that cultivated diamonds = real diamonds, while moissanite is a man-made “gem” that is completely different from diamonds and is sold on the basis of diamonds; But from the perspective of wearing, the bright and shining effect of moissanite also attracts the favor of many consumers, and the price is cheaper, so it can be purchased as ordinary jewelry.

Should I buy lab-grown diamonds or moissanite? If the budget is insufficient and you want to buy a more shiny daily accessory, moissanite is also available. If you have a little more budget, you can choose lab-grown diamond jewelry.

Lab-grown diamonds become an affordable luxury

The price of lab-grown diamonds has continued to decrease along with technological upgrades, and high cost performance has increased its attractiveness to consumers. Around 2016, my country began to try small-scale production and sales of colorless and small-grained cultivated diamonds. With the maturity of domestic and foreign technology, the production cost and retail price of cultivated diamonds gradually decreased.

Because of its price advantage, cultivated diamonds have more abundant consumption scenarios. They can not only be used as diamond substitutes, but also penetrate into the high-end jewelry and mass jewelry markets. They are both practical and fashionable.

Compared with natural diamonds, the price of lab-grown diamonds has a greater price advantage, which can seize the existing market share of natural diamonds, attract price-sensitive people with weaker affordability, and push lab-grown diamonds further into fashion categories with growth potential.

With the improvement of residents’ living standards and people’s willingness to improve their quality of life after the epidemic, cultivated diamonds meet the needs of consumers due to their cost-effective, fashionable and customizable advantages. In the future, with the increase in the frequency of consumption of diamonds and the penetration of cultivated diamonds With the improvement of production rate, the terminal consumption market of nurturing diamonds is expected to further expand.

MW CVD Diamond

MW CVD Diamond is also a hard stone. It is lab created high carbon gemstone. By absorbing the advantages of PVD technology to improve CVD synthesis technology, MW CVD Diamonds is more stable and shining. It’s the diamond imitator, not cubic zircon, hardness ranking at 9.0. It has an RI 2.27 – 2.31, which is lower than moissanite. But because it contains carbon, it also has a very beautiful fire color and high brilliance. It cannot pass the diamond test. Since it can not pass the diamond test, only has product quality certificate.

MW Moissanite

MW Moissanite is a perfect choice. It’s more heat resistant than even diamonds, meaning that even if they were in a fire, they would still retain their sparkle and form. And since it has an extremely high level of brilliance and excellent light performance, it has much higher brilliance and fire than a diamond.

The hardness of moissanite is 9.25, it’s almost the same as diamond. Only for the diamond and moissanite, it can pass the diamond test. Each moissanite has its unique waist code, and it is certified by the international famous professional appraisal organization and the global gemstone Research Association (GRA).
