After Luohu Shuibei ushered in consumers' purchase of gold heat and live broadcast on the merchant line, it gradually attracted a group of consumers who came here to buy diamonds. Recently, in a jewelery wholesale market in Shuibei, reporters saw that there are many young couples who are together here. In addition to gathered in the golden area to buy wedding jewelry, some of them stay in shops that specialize in cultivating diamonds to cultivate diamonds. Essence

A Cheng and the wife who just received the certificate are one of them, they are all post -95s. After understanding the cultivation of diamonds online, use the weekend time to come to water shellfish to see the cultivation of diamonds. "Mainly want to circle the Da Carat Diamond Dream once at a more affordable price," said Acheng.

In the market, reporters found that some consumers could not help but amazed after comparing the price gap between the price of diamonds and natural diamonds: "Why are your big carat diamond cheaper than me?"

Cultivating diamonds is not a local phenomenon in Shenzhen. Last year, CCTV News once launched a voting activity on whether to buy diamonds on Weibo, and 50%of them chose to "buy cultivation diamonds." According to the "2021-2022 Global Diamond Industry" research report released by Bain Council, China's cultivation of the diamond consumer market accounts for 10%of the world and is still growing.

Cultivating diamonds can achieve quantitative production

Cultivating diamonds is not a "alternative" for "fake diamonds" or diamonds, but a laboratory that is consistent with the structure of natural diamonds to cultivate diamonds.

There are many things to cultivate diamonds and natural diamonds. First of all, they are exactly the same in appearance, and they cannot distinguish natural diamonds and cultivate diamonds by the naked eyes. In response, the reporter interviewed Emily, who was engaged in the jewelry appraisal industry in the late evening. Emily told the late night reporter: "Even professional jewelry appraisers have no way to distinguish the cultivation diamonds and natural diamonds from the appearance. But in professional appraisal agencies, they can still distinguish them obviously from the growth lines. "

Secondly, the basic attributes of the two are the same. Both chemical ingredients are carbon, both hardness are 10, the refractive index is 2.42, and the scattered is also 0.044. In addition, the price calculation model of the two is the same, and its price is determined based on carat size, diamond color, diamond cutting, diamond clarity, and later process decisions.

At present, the main difference between the cultivation of diamonds and natural diamonds is the market price. "The price gap between the same and quality of the price of diamonds and natural diamonds with the same quality and the same quality is about 6 times." Said Mr. Lin, a merchant, wholesale market, said.

This huge price difference is derived from the different growth environment of the two. Natural diamonds were formed in the mantle layer of the earth 15 to 200 kilometers a few years ago. Later, the crustal activity was brought to the surface by the magma to the surface. Resources have certain scarcity.

Cultivating diamond growth in modern laboratories is the product of technological development. It is a "thin piece" diamond as a "seed", and then the technicians are used to imitate the high -temperature and high -pressure environment formed by natural diamonds to precipitate the dissolved carbon to the diamond seeds, and the cultivation of diamonds will eventually be born. At present, the growth cycle of cultivation of diamonds is about 3 to 7 days, and quantitative production can be achieved.

Due to the continuous improvement of cultivation technology and the continuous expansion of production scale, the current prices of cultivation of diamonds have declined. Data show that the price of artificially cultivated diamonds in 2016 was about 80%of the price of natural diamonds, but in 2022, this number had dropped to 20%.

Mr. Lin believes that the current price of diamonds still has more room for decline: "The shape of natural diamonds is irregular, and the cost in polishing and cutting is relatively high. At present The price of cultivation of diamonds will be lower. "

More and more consumers accept the cultivation of diamonds

Diamonds have been given many romantic symbols because of beauty and rare, and lovers are regarded as loyal and long -term representatives. When you are new, young people often choose diamond rings as autonomous to witnessed love and marriage. However, the expensive price of natural diamonds has also discouraged many consumers.

Taking the price of natural diamonds as an example, the price of natural diamond rings is very large. According to the different color, clarity, and cutting process, the price range is 20,000 yuan to 70,000 yuan. It reaches more than 200,000 yuan. This is a lot of expenses for young people who just set up a family.

The appearance of cultivating diamonds has brought more choices to young people. Mr. Lin said: "The price of about 20,000 yuan has been able to buy one -carat cultivation diamond ring with excellent appearance, so many young people will be more willing to buy through buying by buying. Cultivate a diamond ring to save a sum of money for other expenses. "

With the increase in the popularity of the cultivation of diamond brands and the increase in the content of the cultivation of diamond science, consumers' stereotypes of the cultivation of diamonds are also being rewritten. Among them, a group of consumers can accept the cultivation of diamonds. Some consumers told a late night reporter: "I think natural diamonds and cultivation diamonds are like natural pearls and artificial breeding pearls. I can accept the cultivation of diamonds."

The other consumer was because the budget was limited to the cultivation of diamonds. "The budget is limited, and I have no vanity." Miss Huang, who was planning to buy diamonds online channels. The increased consumer market also brought vitality to the jewelry market of the shellfish. "Mizuki currently has about a dozen merchants who cultivate diamonds, and overall growth trends." Mr. Lin said.

Cultivate diamonds gradually move towards branding

As the market for cultivating diamonds has continued to expand, the cultivation of diamonds has gradually moved towards the road of branding. In 2016, the Austrian imitation crystal manufacturer Brand Swarovski founded Diama, Diama, the world's largest diamond producer in 2018. Coincidentally, Pandora, one of the world's largest jewelry dealers in 2021, announced that it will stop using mining diamonds to make jewelry and will only use diamonds produced in the laboratory in the future.

At the same time, the cultivation of diamonds in the domestic jewelry market is gradually forming. In August 2021, the domestic first -line jewelry brands such as "Old Temple Gold" and "Yiyi Gold Store" launched their own cultivation diamond brand "Lu Chan" and opened trial operations in the online Tmall flagship store. This is domestic. The first breeding diamond brand launched by the head jewelry dealers.

Looking at Shenzhen, as a city with the nation's largest jewelry trading market, Shenzhen also explored its own path in cultivating the branding of diamonds. At present, Shenzhen has a number of local cultivation diamond brands such as Xiaobaiguang, Kelixi, TOPMIYA, etc., and extends to the country based on Shenzhen, opening experience stores such as Beijing, Shanghai, Nanjing and other places. In addition to physical stores, the laying of online channels is more important for cultivating diamond brands.

For emerging industries, it is extremely important to cultivate consumer habits and cognition. At present, many consumers still do not recognize the cultivation of diamonds. At the same time, the plunge of Mosan's diamonds in the past few years has also affected the market's confidence in cultivating diamonds. Mr. Li, a consumer who came to buy natural diamonds to buy natural diamonds, said: "Cultivating diamonds cannot be bought, it is not worth the future." In this regard, merchants who cultivate diamonds are also thinking about response strategies, such as gradually weakening the scarcity of diamonds. Mainly emphasize decoration and accessories attributes. At the same time, these merchants are also focusing on creating a brand image, increasing the added value of the brand, and enhancing consumer purchasing confidence.
