The Best Ethical + Sustainable Engagement Rings

The Best Ethical + Sustainable Engagement Rings

Thinking of popping the question? I recently got engaged, so I can confidently say sustainable engagement rings have a soft spot in my heart. My fiancé did right by me and proposed using an ethical engagement ring and I couldn’t have been happier – he custom made it and everything too! I get compliments on it everywhere I go, but most importantly, I can feel good wearing it. If you’re an environmentalist, or the person you’re proposing to is, you’ll want to get them a ring that’s as beautiful as it is good for the environment.

Believe it or not, a lot of engagement rings are anything but sustainable or ethical. Harvesting diamonds has a history of fueling conflict and mining precious metals is often detrimental to the environment. Not to mention miners are often denied fair wages, safety provisions or health benefits. Metal mining, gold mining in particular, is one of the most environmentally destructive kinds of mining around.

For socially and environmentally conscious couples, an ethically sourced engagement ring is a must. Thankfully, there are several brands that create sustainable engagement rings using recycled or fair trade metals as well as conflict-free diamonds and jewels. Many of these brands also give back by helping local communities and funding environmental projects.

What is the most ethical stone for an engagement ring?

In many instances the most ethical stones for engagement rings are actually synthetic alternatives made in laboratory. Before you tune out completely or say “Well that is not the same”, from a chemical and physical point of view they are actually completely identical! Not only that, but it also has the added bonus that they are much better for the environment and have significantly higher ethical standards. Always look for conflict-free, lab grown diamonds if you can.

What is an ethical engagement ring?

For me, there are several easy ways to ensure that an engagement ring is ethical and you can show off your gorgeous rock without guilt! The first thing I would always look for is a vintage or second hand ring, however, not everyone is comfortable with that and that is totally fine. An engagement ring is an important symbol in so many cultures so I would always recommend doing what is best for you and your partner. 

Other ethical options are those which have recycled metals, repurposed gemstones or even lab grown diamonds. Whatever your style or taste there are some great options out there. If in doubt, I would always recommend going to a smaller store, as this will often have higher ethical standards as well as having a higher chance of finding some gorgeous and unique rings that will be special to just you and your loved one. 

The Best Ethical + Sustainable Engagement Rings

What is a sustainable ring?

Unlike many other sustainable items, when it comes to sustainable engagement rings, it is much less about the impact of plastic packaging and more about the impact of mining the metals and gemstones, as well as the ethical impacts on the workers involved in this process.  

I’ve gone ahead a listed several brands that make sustainable engagement rings below – but you can always check out Etsy for some beautiful vintage rings as well.

What are the most ethical diamonds?

If you are dead set on the idea of having a diamond, there are really three options available to you. The first is you can opt for a vintage ring, which can be really lovely, especially if you are keen to find a really unique and maybe quirky design. The resources and energy it took to harvest this diamond are already depleted, making it a much more eco-friendly option.

If this isn’t so much up your street, there are plenty of places out there where you can have ‘new’ rings designed using recycled natural diamonds. Both of these options are far more sustainable as they require no new mining of diamonds and therefore require no additional environmental devastation and human exploitation.

The alternative if you don’t want to opt for a previously owned item is to look into lab created diamonds. This is particularly good if you are on a bit of a budge. Lab grown diamonds are a much more affordable option while being physically and chemically identical. 

The Best Ethical + Sustainable Engagement Rings

Why are diamonds not ethical?

Diamonds have an incredibly complicated political history, for which wars have even happen over! This is why you may have heard the phrase blood diamond. Thankfully, there is the Kimberly Process which ensures that at least a minimum level of ethical standards are upheld, although some argue this still isn’t enough. I would need an entire blog post to explain this fully however, they are often sourced through slavery and bloodshed. On top of that, any kind of mining has a detrimental impact on the environment so this adds to the complications of the diamond. 

What is the most eco-friendly gemstone?

When it comes to eco-friendly gem stones there are three main options. First, and the most eco friendly is to go for a vintage or recycled gemstone. The carbon footprint of this will always be as minimal as possible.

Alternatively, if you are dead-set on having a new gemstone you can opt for a lab grown diamond or a Moissanite gemstone. Lab Grown diamonds are chemically and physically exactly the same as natural diamonds and only differ from their origins, with lab grown being the far more sustainable. It is additionally much quicker to create a lab grown diamond which takes around 2 weeks compared to millions of years for a natural diamond.

If you are looking for a non-diamond alternative you can also look into moissanite, which was developed as a more sustainable alternative to diamonds and is more affordable. Moissanite doesn’t have the same chemical make up as a diamond.

Where can I buy an ethical engagement ring?
