The remarkable increase in synthetic diamond production, coupled with a continuous decline in prices, is making a significant impact. What was once a topic confined to technical discussions in specialized industry publications has now entered the mainstream media spotlight as the presence of synthetic diamonds in the market garners increasing attention.
The sales trend of synthetic diamonds, often referred to as “lab-grown diamonds” in the trade, appears poised to sustain its impressive growth. Current reports estimate production at around 6 to 7 million carats, with forecasts indicating further expansion.
For example, France 24’s report titled “Lab-grown diamonds put natural gems under pressure” highlights key distinctions between natural and lab-made diamonds, emphasizing their formation age and cost differences: «the glittering diamonds sparkle the same but there are key differences: mined natural gems are more than a billion years old, while laboratory-made rocks are new and cost less than half the price».
Additionally, the report shows how «in Smit Patel’s gleaming lab, technicians drop crystal diamond “seed” slices into reactors mimicking the extreme pressure far underground». Furthermore, it notes that «Lab-grown diamond exports from India tripled in value between 2019 and 2022, while export volumes rose by 25 percent between April and October 2023, up from 15 percent in the same period a year earlier, according to the latest industry data».
Indian synthetic diamond exports have seen a substantial increase, as noted by the Gem and Jewellery Export Promotion Council (GJEPC), with a 42 percent year-on-year growth in carat exports between April and October 2023.
The Times of India discusses the trends in “lab-grown” diamonds in the article “Are lab-grown diamonds going out of trend? Here’s what jewel experts have to say”. It notes the recent surge in popularity is due to marketing and promotion inspired by sustainability and ethical concerns.
However, experts foresee a decline in demand as consumers recognize drawbacks like rarity and transparency issues. While synthetic diamonds offer affordability and environmental benefits, they may face challenges when competing with the enduring appeal and inherent value of natural diamonds.
From an American perspective, a December CBS News article reflects the growing popularity of man-made diamonds due to their resemblance to natural stones and affordability, with sales increasing from less than 1% in 2015 to approximately 20% globally. Again the theme of ethical concerns and alleged better environmental impact, the legend reduction of labour exploitation is stressed.
According to the article, the sanctions on Russian diamonds further boost demand. As more producers enter the market, prices drop. “Lab-grown”diamonds lack resale value but offer affordability.
Even in Chinese news, synthetic diamonds are being discussed, «a rare commodity with a price only a third of natural diamonds».There is no shortage of a certain degree of national pride.
For instance, it is claimed that in the HUAYU Microwave laboratory in Chengdu, a thin square sheet of about 0.3 millimeters transforms into a 1-carat artificial diamond after 15 days. This process represents a significant technological advancement and requires careful attention. In the future, Chengdu Huayu Microwave will focus on globally innovating the entire industrial chain.
It seems that countries around the world have different opinions regarding synthetic diamonds, especially when it comes to ethics and environmental impact.
Building on a recent National Geographic article, synthetic diamonds are frequently praised for their perceived social and environmental benefits compared to mined diamonds. However, experts hold diverse viewpoints on this matter. Despite lab-grown diamonds being cheaper and promoted as eco-friendly, some contend that mining contributes to socioeconomic advantages for many African countries involved in the diamond mining industry.
