Earth’s Treasury features one of the widest selections of ethically sourced colored gemstones available online. We work closely with professional artisans who craft beautiful jewelry using gemstones that come directly from the mine to the market.

At Earth’s Treasury, we love the process of working with clients to help make their custom natural gemstone jewelry vision come to life. Whether you prefer a classically styled piece or a truly unique custom design, we can make it happen. We will work with you through the design, prototyping, casting, and production processes to craft your dream piece of jewelry.
While our collections contain colored gemstones from all over the world, our true passion is for North American gemstones. We work with American miners to source stones such as the brilliant Montana sapphire, gorgeous Oregon sunstone and colorful tourmaline from California and Maine. There is a remarkable diversity of colored gemstones available right here in America, many of which are rarer and more valuable than diamonds!
If you have any questions about our collection, don’t hesitate to reach out to us. We’re here to help you through the process of finding the perfect natural gemstone jewelry or loose gemstones online.
