The Truth About Lab Grown Diamonds and Sustainability: 8 Things to Know (2024)

Lab-grown diamonds have been gaining popularity in recent years as a sustainable and ethical alternative to traditional mined ones. They are created in a controlled laboratory environment using advanced technology and are chemically and physically identical to natural diamonds.

1. What are Lab Grown Diamonds?

Lab-grown diamonds, also known as synthetic diamonds, are created through a process called chemical vapor deposition (CVD) or high-pressure-high temperature (HPHT). In CVD, a diamond seed is placed in a vacuum chamber and a gas mixture is introduced, which is then ionized into plasma.

This plasma then causes carbon atoms to adhere to the seed, layer by layer, until a diamond is formed. HPHT involves subjecting a seed to high pressure and high temperature in the presence of a carbon source, which then causes the diamond to grow.

2. Environmental Impact of Lab-Grown Diamonds Compared to Mined Ones


One of the main arguments for a lab grown diamond is its reduced environmental impact compared to mined ones. Traditional mining involves extensive excavation, land disturbance, water use, and energy consumption.

Mining also generates significant amounts of waste, which can lead to soil and water pollution. In contrast, the production of lab-grown ones requires much less land, water, and energy. The emissions and waste produced during the process are also much lower.

3. The Process of Creating Lab Grown Diamonds

Creating lab-grown diamonds involves a highly controlled and regulated process. They are grown in a laboratory setting, under strictly controlled conditions. The process is highly automated, using advanced technology to create a consistent and high-quality product. The resulting pieces are then cut and polished to create the finished product.

4. The Social and Economic Impact of the Diamond Industry

The diamond industry has a significant impact on the economies and societies of many countries. It provides employment and generates revenue, but it can also lead to social and economic inequality.

In countries where they are mined, the profits often go to a small group of individuals or companies, leaving the rest of the population without access to the benefits. In addition, the industry can contribute to corruption, conflict, and human rights abuses.

5. The Affordability and Accessibility of Lab-Grown Diamonds


One of the advantages of lab-grown diamonds is their affordability and accessibility. Because they are produced in a controlled environment, their supply is more predictable, which can lead to lower prices. This makes them a more affordable option for many consumers.

In addition, their availability means that consumers have access to a wider range of options when it comes to choosing a diamond.

6. The Future of the Diamond Industry and Sustainability

The diamond industry is undergoing a significant transformation, with lab-grown diamonds playing an increasingly important role. As consumers become more aware of the environmental and ethical concerns surrounding traditional mined ones, the demand for them is likely to increase. The industry will need to adapt to this changing landscape, with a focus on sustainability and transparency.

It is important to note, however, that not all of them are created equal. Some companies may use less sustainable production methods, or may not be transparent about their processes. Consumers should do their research and choose a reputable company that is committed to sustainability and ethical production practices.

As for the phrase “lab-grown diamond”, it is worth noting that there has been some debate about the language used to describe them. While some prefer the term “lab-grown” or “synthetic”, others argue that these terms carry a negative connotation and prefer “cultured” or “created”. Ultimately, the language used is up to individual preference, but it is important to be clear about what is meant to avoid confusion.

7. How to Distinguish Between Lab Grown and Mined Diamonds?


One of the most common questions that consumers have when it comes to lab-grown diamonds is how to tell them apart from mined ones. While they are virtually identical to their mined counterparts in terms of physical and chemical properties, there are a few key differences that can help you distinguish between the two.

  • First and foremost, the price can be a giveaway. Lab-grown diamonds are generally less expensive than mined ones, especially those of a similar size and quality. However, this alone is insufficient to determine whether a diamond is a lab grown or mined.
  • Another way to tell the difference is by examining its growth patterns. Lab-grown diamonds typically have a more consistent growth pattern than mined ones, which can have irregularities due to the natural growth process.
  • You can also look for tiny inclusions or imperfections within the diamond itself. Mined ones often have small impurities or flaws, while lab-grown ones tend to be more flawless due to their controlled growth process.
  • Ultimately, the most reliable way to determine whether a diamond is lab grown or mined is through a certification process. Reputable laboratories can analyze its properties and provide a certificate that identifies whether it is natural or lab-grown.

8. Consumer Attitudes Towards Lab-Grown Diamonds and Sustainability


As more and more consumers become aware of the environmental and ethical concerns surrounding mined diamonds, there has been a growing interest in lab-grown ones as a more sustainable and responsible alternative.

In a survey conducted by the Diamond Producers Association in 2019, 70% of respondents said they were interested in purchasing a lab-grown diamond, while 16% said they would not consider it, and 14% were undecided. The survey also found that the primary reasons for considering them were their affordability and the belief that they are more sustainable and ethical.

However, not all consumers are convinced that they are the answer to the problems associated with mined diamonds. Some argue that they are not truly sustainable, as they still require significant energy and resources to produce. Others are concerned about the potential economic impact on communities that rely on the diamond mining industry.

Ultimately, the decision to purchase a lab-grown diamond is a personal one that depends on individual values and priorities. However, it is essential for consumers to be informed about the options available and to choose companies that are committed to sustainability and ethical production practices.

By doing so, we can all contribute to a more responsible and sustainable diamond industry.
