Transform your timeless moments into exceptional jewelry with a one-of-a-kind piece as distinctive as you.
We use our expertise to guide you seamlessly through the purchase of heirloom-quality jewelry you’ll love to wear or give – made with ethically sourced materials you’ll feel great about.
Mercurius believes that the origin of each part is inseparable from the complete beauty of the finished object, so the team carefully sources all materials – including Fairmined Certified gold, traceable colored gemstones, and post-consumer recycled and lab-grown diamonds.
From design to final production, all pieces are lovingly created at our studio on Huchiun Ohlone land in Oakland, California, with a commitment to ethics and transparency.
Crafted from unique materials that showcase the abundance, mesmerizing patterns, and stunning variation of the natural world, the timeless and talismanic jewelry invokes a sense of magic and elemental balance.
A ring worn daily is an intimate and powerful piece of jewelry, reminding you of what you value most each time it catches your attention. Especially when that ring is symbolic of vows you’ve made to each other or yourself.
Ethically sourced, thoughtfully designed, and expertly crafted – our Commitment Collection is created to be well-loved and worn for a lifetime.
All Commitment Collection Rings are made to order, tailored just for you.
Founded in 2007, Mercurius is an Oakland-based ethical fine jewelry brand that borrows its name from the centuries-old philosophy of Alchemy. Husband-and-wife team Alisa and David Thorp are captivated by alchemical theory, which posits that elements in perfect balance – air, fire, water, and earth – are forces of nature that can unleash the spirit within matter and reveal something greater than the sum of its parts.
