If you consider yourself a conscious consumer, a minimalist, or simply care about the impact your purchasing decisions have on the world around you, then you know that less is more. This could not be more true than when it comes to jewelry. Most of the fine jewelry you purchase will probably still be in your possession for many years to come, so you want those pieces to be special, beautiful gems that you really love and feel represent you. And of course, that means prioritizing ethics, sustainability, and transparency in the production process, too.
Here’s what to look for from ethical, sustainable fine jewelry brands
Lab-grown diamonds. Unfortunately, if you’re buying diamonds, you have to use your discretion. We recently wrote about how it’s practically impossible to 100% ensure ethical sourcing of mined diamonds, even with things like the Kimberley Process and “beyond conflict-free” claims. That’s why it’s understandable that lab-grown diamonds, which don’t have the traceability problem and are also less taxing on the environment, are growing in popularity. And yes—they are real diamonds!
Recycled and/or ethically sourced gems. Some of the brands below use recycled diamonds and other types of gemstones, taken from old pieces or “scraps” from larger stones and then redesigned. This is an excellent low-impact option as well. After recycled, go for ethically-sourced gems. Brands who source from transparent and ethical mines are still a much better option than traditionally-mined companies (where you can be almost certain that human and environmental degradation is happening in order to get that gem to you). Don’t be afraid to ask the brand questions about their pieces and request verification!
Recycled metals or ecological gold: Recycled materials are almost always better than virgin. We need to recycle as much as possible and toward a truly circular economy that doesn’t just dig up resources and then throw them away. But recycled gold does come with its own troubles, so you could also choose ecological gold when possible (though there are very few brands creating with ecological gold as of right now).
Vintage / Secondhand pieces: Unlike clothing, which continues to slowly degrade over time, well cared for fine jewelry can actually become even more beautiful and valuable as it ages. And of course, since there aren’t additional resources needed to create a new piece, this is one of the most sustainable options available!
Excellent customer service and return policies. Buying fine jewelry online means you’re probably spending a lot of money on something that you might not even be able to see, hold, or try on in real life before you buy it. What happens if you get it and it doesn’t look like what you thought it would? Before you drop a chunk of change, make sure the brand you’re buying from has a readily-accessible customer service department, and a clear return/exchange policy that will work with your situation should you need to use it. Some of the brands below also have at-home ‘try before you buy’ programs you can take advantage of.
Buy what you love! Lastly, when it comes to purchasing ethical and sustainable jewelry, buy pieces you really love. Pieces that you feel represent your personal vibe and could see yourself wearing for a really long time or even passing down to a younger loved one.
