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!
