“Cultivated diamonds”- Industrial Materials to Jewelry

Release time:



With  development of science and technology,the technology and methods for cultivating diamonds have become increasingly mature. In recent years, cultivated diamonds have been entering the field of vision of the jewelry industry in various forms,. consumers and natural diamond merchants don't have open and inclusive attitude for cultivated diamonds.

Diamonds are mainly composed of carbon, and may contain various trace elements.with successful marketing, the diamond-"king of gems" has given a meaning of love and loyalty,wich making it one of the most coveted luxuries for every woman. Diamonds are mainly produced in Africa, Australia and Canada, while China's diamond resources are relatively limited, mainly located in the Yuanjiang River basin in Hunan, Mengyin in Shandong, and Wafangdian in the southern part of Liaoning.

With the improvement of people's living standards, the pursuit of material life is also increasing, and the demand for diamonds is also growing. The mining of many large natural diamond mines has gradually entered the countdown.   With natural diamond mining increasingly damages the earth's environment and mining costs continue to rise, natural diamonds will gradually be exhausted in 40 years. Currently, cultivated diamonds are slowly increasing market supply, after 40 years,cultivated diamonds will surpass and replace natural diamonds, just like farmed pearls have replaced natural pearls.

such as "synthetic" and "artificial" as prefixes has led many consumers and even natural diamond industry practitioners to believe that cultivated diamonds have high production volume,high quality, and low prices. Rome wasn't built in a day, and diamonds are not so easy to "create" either. The emergence of cultivated diamonds seemed to transform them overnight from industrial diamonds into substitutes for natural diamonds in jewelry. However, this is not the case. Cultivated diamonds have a long history of industrial applications, and the use of cultivated diamonds for jewelry can be traced back to the last century. In 1953, General Electric (GE) in the United States successfully synthesized cultivated diamonds using the high-pressure high-temperature (HPHT) method. Currently, there are mainly two methods for cultivating diamonds on the market: HPHT and chemical vapor deposition (CVD). The HPHT method mainly grows small diamonds, while the CVD method mainly grows large, high-quality diamonds.

In the early days of the market, HTHP cultivated diamonds were mainly yellow and various colors, but their clarity was not high enough and their prices were too high to gain market recognition, resulting in poor sales. , IIa company in Singapore used the CVD method to produce colorless cultivated diamonds. CvD diamonds began to trial sales on the Gemesis website in the United States, which attracted the attention of the jewelry market.At that time, most CVD diamonds were in the F to I color range, with clarity ranging from VVS to S1.

after decades of improvement, cultivated diamond technology for jewelry purposes has become quite mature, and can produce diamond sizes ranging from small diamonds to dozens of carats, colors ranging from pure white to various colors, clarity ranging from purest to minimal impurities.

In fact, the way cultivated diamonds entered the consumer's field of view was not good, as they attracted high attention from consumers and jewelry industry practitioners by pretending to be natural diamonds.in the early days, when De Beers sold cultivated diamonds,he would emphasize that cultivated diamonds were only sold as accessories, and would punch a hole in the waist of the diamond. At that time, their promotion still had the meaning of belittling cultivated diamonds.However, De Beers broke its long-term sales policy in September 2020 when it began selling cultivated diamonds.De Beers established the Lightbox brand  for selling cultivated diamonds.De Beers' retail prices without certificates do not leave enough profit margins for each link in the supply chain, mainly because many manufacturers have technological limitations that prevent them from having high production volume while meeting high quality standards. The production volume of cultivated diamonds currently cannot meet the market demand. technological iterations will eventually lower the cost of production, but this requires time to accumulate. Undeniably, De Beers' market price can serve as a reference price for the industry, and cultivated diamonds will maintain this price for quite some time until the synthetic technology becomes more advanced and cost-effective, which may then lead to a possible decrease in cultivated diamond prices.

The price of natural diamonds has been relatively stable, and many consumers recognize and accept it due to the natural, scarcity, and emotional value of diamonds themselves.Among them, scarcity prompts consumers to have strong expectations for the value preservation and appreciation of diamonds. natural diamonds will indeed become scarce in the future, as most natural diamond mines will be depleted in about 10-15 years, and the remaining few deposits will be exhausted in 40 years.

diamonds with a "natural" identity become more valuable as they become scarcer?According to relevant data, the mining cost of natural diamonds is increasing. Among the diamonds that are mined, the price of large-sized, high-quality diamond roughs has been rising, while the price of small-sized, low-quality diamond roughs has been constantly declining. The retail prices of natural finished diamonds with medium-low quality and medium-small size are also constantly decreasing, and their sales volume is declining. This phenomenon is not only due to the impact of the international economic downturn in recent years but also related to the continuous decrease in the price of cultivated diamonds, the continuous improvement in quality, and the continuous increase in market share.

diamonds have poor cashability,wich the ways of recycling are generally limited to pawnshops and jewelry retail stores. Jewelry retail stores only accept consumerExchange purchase,diamonds cannot be directly cashed in like gold.small diamonds are not recycled, and the recycling price of large diamonds is only about 30% of the purchase price., it can be seen that even if diamonds are labeled as "natural," not all natural diamonds can achieve value preservation and appreciation.From the current market situation, the growth and decline trends of natural diamonds and cultivated diamonds are already very clear and irreversible. When the selling price of natural diamonds is lower than the mining cost, diamond mines will stop mining, and cultivated diamonds will gradually surpass and replace natural diamonds. The value of diamonds is not determined by their origin. In the future, high-quality, large-sized natural diamonds will be very scarce and expensive. Compared with other natural diamonds that do not have the ability to preserve value, cultivated diamonds will become a better alternative.
