When it comes to purchasing a diamond — whether for an engagement, an anniversary, or an heirloom piece — the question of ethics is increasingly top of mind. As laboratory-grown diamonds continue to gain popularity, many buyers wonder: are these man-made gems genuinely a more ethical alternative to natural diamonds?
At Prins & Prins, we believe in informed luxury. Let’s explore the real differences between natural and lab-grown diamonds — not just in their formation, but in the broader social and environmental impact they carry.
One of the most profound differences between natural and lab-grown diamonds lies in who benefits from their creation.
The natural diamond industry supports the livelihoods of more than 10 million people globally, generating over $16 billion annually in socioeconomic and environmental contributions. In countries like Botswana, Namibia, and Canada, up to 80% of the wealth generated through diamond mining remains in the local economy — transforming entire communities through investments in education, healthcare, infrastructure, and conservation.
These are not just luxury stones; they are catalysts for development, empowerment, and progress.
In contrast, lab-grown diamonds, while technologically innovative, are often produced in large-scale industrial facilities backed by a small group of venture capitalists and private investors. The profits tend to stay concentrated in the hands of a few, with minimal benefit to local communities. Furthermore, far fewer people are employed in the lab-grown diamond sector — meaning the impact on job creation and economic empowerment is significantly lower.
There is a common assumption that lab-grown diamonds are better for the environment. However, a closer look reveals a far more nuanced picture.
Thanks to decades of reform, the natural diamond industry has made major strides in sustainability. Today, the carbon footprint of a one-carat natural diamond is comparable to that of manufacturing a MacBook laptop. Many diamond producers are actively working toward carbon neutrality, and for every acre of land used in mining, an average of three acres are restored for conservation.
Conversely, lab-grown diamonds are created using highly energy-intensive processes that replicate the heat and pressure of Earth’s mantle — often requiring temperatures of over 2,700°F. This process consumes significant amounts of electricity and water, and most production still occurs in countries like China and India, where coal-powered electricity is dominant. While a handful of producers claim to use renewable energy, this is far from the norm.
At Prins & Prins, we understand that ethics in luxury is not just a trend — it’s a responsibility. That’s why we source our natural diamonds from trusted suppliers who adhere to the highest standards of ethical and sustainable mining. Our diamonds are conflict-free, traceable, and responsibly sourced, ensuring our clients enjoy the beauty of their jewellery with a clear conscience.
While lab-grown diamonds offer an alternative for budget-conscious consumers, they currently fall short of delivering the same level of transparency, community benefit, and environmental integrity as natural diamonds.
Beyond ethics, there’s another important consideration: value retention.
Natural diamonds are finite — formed deep within the Earth over billions of years. Their rarity, durability, and historical value make them enduring assets. Lab-grown diamonds, however, are mass-produced in increasing volumes, which continues to drive down their resale value. For clients seeking to pass their jewellery on as heirlooms or preserve long-term value, natural diamonds remain the superior choice.
As a trusted name in fine jewellery in South Africa, Prins & Prins is proud to offer exquisite natural diamonds that are not only beautiful, but also ethical, sustainable, and impactful.
