16 best sustainable engagement rings made by eco-friendly brands

On the hunt for a stunning engagement ring with a conscience? We’ve compiled some of the best ethical and sustainable engagement rings to buy right now, from gorgeous gemstones to lab-grown diamonds.

For decades, diamonds have been the traditional choice of stone when it comes to choosing engagement rings. Recognised as one of the strongest, naturally occurring compounds on earth, diamonds are symbolic of the kind of enduring love and commitment that can last a lifetime. However, as society has grown more aware of the detrimental impacts diamond mining has on our natural environment, consumers are becoming more interested in less harmful alternatives.

It’s no secret that in recent years the topic of sustainability has dominated conversations in the fashion industry. Many brands have adopted environmentally friendly practices to show solidarity with this movement, which has become an undeniable focus for many retailers, including those working in the jewellery industry. With this push for change, many manufacturers have started to embrace more sustainable practices, from recycling metals to offering lab-grown diamonds in response to their rising popularity. In fact, lab diamonds have become so mainstream in recent years that they’re now widely available in high-street stores such as Swarovski and Pandora.

For those who don’t feel that a diamond is right for them, many are turning to colourful gemstones when it comes to choosing an engagement ring. These unconventional stones have been a hit amongst A-list celebrities such as Gwyneth Paltrow, Eva Longoria, and Halle Berry, who have all effortlessly rocked these colourful stones. The royal family is no exception - just take a peek at Kate Middleton's sapphire engagement ring as proof!

There's no doubt that an engagement ring can be a huge dealbreaker, making the quest for the perfect ring daunting. The good news? Broadening your options in this way will provide you with a wider selection of inexpensive and uniquely crafted rings, better suited to the distinct personal style of your partner.  

For those of you who are still not quite sold on the idea of foregoing a natural diamond ring, we’ve put together a simple guide to our favourite sustainable engagement rings on the market right now.
