About Old Main Gem Co.

I started Old Main Gem Co. to give memories a place to live — creating jewelry that captures the moments that matter most. Inspired by my childhood in Logan near Utah State's Old Main building, I believe every piece should tell a story that's uniquely yours.

At Old Main Gem Co., we don't just make jewelry — we make it together. Every piece begins with a conversation, working closely with you from the first sketch to the final polish. Using only high-quality materials, ethically sourced gems, and expert craftsmanship, we create keepsakes that reflect both your story and our commitment to excellence.

This isn't just custom. It's keepsake. Where sentiment meets style.

Why Clients Choose the Old Main Way

Traci Diamond Ring Review

TRACI L.

This is hands down the sparkliest ring I’ve ever seen. I get compliments from strangers constantly — it truly catches the light (and everyone’s attention). My husband surprised me with it, and he said the design process was smooth and way faster than he expected. We couldn’t be happier.

Sandy Redesign Review

SANDY C.

The original stone lacked the color and clarity I really wanted. This new one is bigger, brighter, and completely changes the look of the ring — in the best way.

ELISE R.

I got this as a birthday gift to myself, and it’s perfect. The peridot has such a bold, beautiful glow, and the design feels so unique and special.
