11 Certified sustainable Fine Jewelry Brands

At Gardens of the Sun, we’re all about digging deeper - literally and figuratively.

And we’ve made it our business to actually be ethical: from mercury-free gold sourced by indigenous women to transparency about every step of the process. 

Starting out, we had a big dream in a small studio. We knew the jewelry world could do better - less take-make-waste, more sustainability.

We wanted to prove that jewelry could be a force for good - from the way we source our gemstones and metals, to how we treat our team and everything in between. Our B Corp score of 82.3 might not have us at the top just yet, but it's a score that both marks our commitment to do better and be better, AND shows we're still learning, growing, and improving. It's a humble yet honest reflection of our promise to never settle for “good enough”.

Based in Indonesia, we work with mercury free gold, mined by incredible indigenous women. Our artisanal mining partners see better paydays and work under safer conditions, thanks to the standards we’ve set. Plus, we push boundaries on what it means to be transparent in the jewelry industry, giving you a clear view of our supply chain from start to finish.

This means we can proudly say our jewelry is crafted in a way that gives back at least as much as it takes.

Over a century of family heritage meets modern responsibility in Singapore. This commitment is reflected in their meticulous sourcing of gems and the personal touch they add to each handcrafted piece, so beauty is never compromised for ethics.
