Lab-Grown Diamonds: An Emerging Ethical Alternative of Purity, Design, and Sustainability

Highlights:

• Introduction
• Minimizing environmental impact without quality compromise
• Consistency in production and innovation in design

Composed of pure carbon atoms arranged in the crystal structure that defines a diamond, lab-grown diamonds possess identical physical, chemical, and optical properties of mined diamonds. However, contrary to mined diamonds, which have been historically associated with issues such as environmental degradation, labor exploitation, and human rights abuses, lab-grown diamonds offer a guilt-free alternative. They are produced with minimal environmental impact and without the ethical concerns that often shadow the diamond mining industry.

The technology, first used by Union Carbide and General Electric in 1951, has made lab-grown diamonds available to meet a customer base that seeks a lavish collection of diamonds, particularly those produced by chemical vapor deposition methods. Alongside their insignificant environmental impact, these diamonds are of higher quality, less costly, and often larger than the mined diamonds. In a way, these diamonds have democratized luxury in the jewelry business, with educated consumers revolting against monolithic pricing of mined diamonds that are not traded, indexed, or banked.

Minimizing environmental impact without quality compromise

The process of mining natural diamonds is harmful to its ecological footprint and involves extensive land disturbance, water usage, and energy consumption. Contrary to traditional mining, which involves significant land disruption, habitat destruction, and water usage, lab-grown diamonds are created in controlled environments using advanced technology. This process eliminates the ecological impact associated with mining, such as soil erosion and wildlife displacement. For example, Diamond Foundry utilizes plasma-enhanced chemical vapor deposition (CVD) technology to replicate the natural diamond-growing process. Their facilities are designed to mimic the conditions under which diamonds form in the Earth's mantle but in a controlled setting. Furthermore, it reduces carbon emissions by overcoming the energy-intensive processes of extracting and transporting natural diamonds. MiaDonna utilizes renewable energy sources such as wind and solar power to run its diamond-growing facilities. It reduces its carbon footprint avoiding the energy-intensive processes of mining, transporting, and cutting natural diamonds, conserving natural resources, and reducing overall environmental impact. Truly Brilliant Collection also aims to produce 50% of certified lab diamonds, made from renewable energy resources by 2050.

Moreover, lab-grown diamonds are produced through advanced technological processes such as Chemical vapor deposition or high-pressure high-temperature methods. In CVD, a diamond seed crystal is placed in a controlled environment where carbon-rich gases like methane are introduced. These gases break down and deposit carbon atoms onto the seed crystal, layer by layer, forming a diamond over time. HPHT involves subjecting a diamond seed to high pressure and temperature conditions like those deep within the Earth, encouraging carbon atoms to crystallize and form a diamond. These methods show that lab-grown diamonds can achieve high purity levels with minimal impurities, rivaling the clarity of natural diamonds.

De Beers introduced its lab-grown diamond brand, Lightbox in 2018 after an initial doubt that these diamonds could capture the market. Till 2020, a 3.5% share of the diamond market came from these diamonds. It has reached 5% in 2021, i.e., $3.9 billion in the U.S. Furthermore, the global lab-grown diamond industry is expected to reach $59.2 billion in 2032 with a CAGR of 9.6%.

Consistency in production and innovation in design

The controlled production environment of lab-grown diamonds provides a consistent supply of gems that meet market demands. They can be produced in various sizes, shapes, and colors on demand. This flexibility in supply enables jewelry designers and retailers to cater to diverse consumer preferences and create customized pieces without the constraints imposed by the availability of natural diamonds. A Russia-based diamond company, Alrosa estimated that in 2021, sales of raw and polished diamonds garnered a revenue of $4.16 billion, while rough diamond sales accounted for $3.97 billion. In the same year, WD Labs acquired J2 Materials which allowed WD Labs to grow high-quality and high-performance diamond substrates for several applications.

Designers are also increasingly drawn to the unique characteristics of lab-grown diamonds, like their ability to be produced in vibrant colors or larger sizes that are rare or costly to obtain naturally. This creative freedom allows designers to experiment with traditional jewelry design, offering consumers a range of distinctive and innovative pieces that display the brilliance and allure of lab-grown diamonds. For instance, Vrai (formerly known as Diamond Foundry) specializes in creating engagement rings and fine jewelry using lab-grown diamonds that are sustainably produced. Their designs emphasize modern aesthetics and ethical sourcing, appealing to consumers looking for high-quality, environmentally conscious alternatives to traditional mined diamonds.

Closing lines

Initially viewed as an alternative to natural diamonds, lab-grown diamonds are now increasingly perceived as a desirable choice. Organizations like the Gemological Institute of America (GIA) provide certification and grading for lab-grown diamonds, further legitimizing their status and assuring consumers of their quality and authenticity. Established diamond companies and retailers have begun to embrace lab-grown diamonds as part of their offerings, recognizing the shifting preferences of consumers and the potential for growth in this segment. This shift in perception, conscious eco-friendly choices of educated buyers, and creative interest of designers have added to the expansion of the lab-grown diamond industry allowing it to capture a significant share in the broader jewelry industry.
