Best Ethical Engagement Rings – Where to Buy Sustainable Diamond Rings

Searching for the perfect engagement ring can be a stressful endeavor at the best of times. Choosing the right style and size, while knowing it’s a “forever” ring, can be difficult enough. But adding in the ethical implications of your new bling may just be enough to make your head spin!

It’s no secret that diamonds and the methods by which they are harvested are far from ideal. From employing child labor to their detrimental impact on the environment, any eco-conscious couple would do well to find an alternative way of declaring their eternal love than buying a conflict diamond.

But what’s the alternative?

Luckily, lab-grown diamonds are becoming more widespread and accessible. And the good news is that they’re virtually indistinguishable from earth-mined diamonds. But the best bit for any soon-to-be engaged couple is that they won’t cost you the earth either. Lab-grown diamonds can be up to 40% cheaper than their traditional counterparts.

Of course, new lab-grown diamonds aren’t the only way to say “I do”. There are also certified conflict-free diamonds, or why not buck the trend and opt for a different stone altogether? Ethically sourced or lab-grown gemstone rings can offer a colorful alternative. You also could look to antique shops for a unique vintage piece, or upcycle an old family heirloom into a new bespoke ring.

Choosing an ethical diamond ring to propose with will have all the more meaning when you know you’re not contributing to human or environmental harm with your purchase.

Why Buy an Eco-Friendly Engagement Ring

Buying an ethical engagement ring is now more accessible than ever with brands such as those featured above providing transparency around their materials and sourcing. But if you’re still not convinced that eco-friendly engagement rings are the right way to go, let’s have a more in-depth look at why you might want to reconsider.

Environmental Impact of Earth Mined Diamonds

The environmental impact of earth-mined diamonds is immense. If you’ve ever seen a photo (like the one below) of a diamond mine, you’ll immediately see why.

Large amounts of land are dug up to search for diamonds. This destroys natural habitats, causes population displacement, disrupts ecosystems, and in turn, the local wildlife. These mines are often abandoned when they’re no longer profitable, and left as gaping holes in the landscape.

Add to that the large fossil-fuel-driven machinery needed to work the mines, the waste rock left over from the mining process which can leak heavy metals into the environment, and the excessive water consumption (in areas typically already in short supply) needed to mine diamonds, and it paints a pretty bleak picture.

Human Impact of Earth Mined Diamonds

The impact of conflict diamonds on communities is a complex issue. Known as “blood diamonds”, the process of mining these diamonds is littered with human-rights abuses, including child labor, unfair wages, unsafe working conditions, and violence.

Then there are the communities misplaced when diamond resources are found in an area. This displacement is often forceful, and violent – to the extent that one displacement of a local tribe in Botswana has been labelled as a genocide.

The trade of these conflict rough diamonds is also said to have funded Civil Wars in several African countries, killing millions of innocent people in the process.

What About Conflict-Free Diamonds?

The Kimberley Process was established as a benchmark for conflict-free diamonds, however, it has been criticized as being an imperfect solution, albeit the most comprehensive one available at present.

Some argue that, when conducted sustainably, earth-mined diamonds can provide a much needed income source for local workers and improve living conditions in the communities in which they operate.

Conflict-Free Diamond Mining & The Environment

While the primary consideration for conflict-free diamonds are the people who mine them, and the communities around the mines, attention is also given to environmental impact and guidelines are put in place to minimize these.

Human & Environmental Impact of Mining for Gold

Like diamond mining, gold mining is a destructive activity that has lasting environmental and humanitarian concerns. It can displace local people, contaminate water supplies, destroy ecosystems, and have unsafe working conditions. To mitigate this damage, the environmentally friendly engagement rings featured in this article utilize primarily recycled gold, or sustainably mined gold.

Gold can be recylced infinitely without degradating the quality, so it makes sense to reuse already-mined gold in this way.


What is an ethical engagement ring?

An ethical engagement ring is one that is sourced using materials that cause as little harm to the environment as possible, and one that is manufactured using fair labor and low-impact manufacturing practices.

Ethical rings are often created using lab-grown or conflict-free diamonds, along with sustainable materials such as recycled gold or platinum.

Are diamond rings ethical?

Diamond rings are classed as ethical when they are sourced by conflict-free mines that ensure the safety of miners, pay them a fair wage, and give back to the community. Diamond mines, whether well managed or not, still have environmental impacts, so arguably the more eco-friendly option is to purchase a lab-grown diamond ring.

Final Thoughts on Sustainable Engagement Rings

Choosing a ring to symbolise your love doesn’t have to come at the cost of human lives or environmental damage.

Now that you know how easy it is to choose ethically sourced engagement rings it really is a no-brainer to do the right thing. And the bonus is that you’ll get to choose or design an eternaly beautiful piece that may just end up costing you less than a traditional ring.
