At Old Main Gem Co., we believe jewelry should tell a story — your story.

We specialize in custom jewelry design that begins with a moment, a memory, or a material that holds meaning. Whether you’re drawn to lab-grown diamond engagement rings, a ring made from dinosaur bone, or a completely new idea, we’ll help bring your vision to life.

Our process is thoughtful, collaborative, and tailored. No templates — just one-of-a-kind, handcrafted jewelry designed for meaning and made to last. Whether you’re in Utah or connecting with us online, we’re your personal partner in crafting bespoke rings, necklaces, and heirloom-worthy pieces.

We work with sustainable diamonds, uncommon materials, and most importantly — your story. Because at Old Main Gem Co., we don’t just make jewelry. We make jewelry that feels as meaningful as it looks.
