"We wanted to use my late husband's yellow gold wedding band as part of our son's wedding band, but didn't want it to be sent away to be created. Alloy was fantastic to work with in creating a design and took such care of the heirloom ring in the process. The end result was exactly what we had hoped for and more!"

"Aram (owner) really cares about his work and craftsmanship. You can really tell he wants to give you an excellent product. After getting my ring sized, I had my and my husband's wedding bands custom designed here — and the experience was exceptional from start to finish."

Why Alloy Custom Jewelers?

Alloy Custom Jewelers is a modern jewelry design studio in Cedar Falls, Iowa, led by designer and founder Aram Susong. We approach jewelry as architecture in miniature — every line considered, every proportion intentional. Our design-forward philosophy focuses on how a piece truly lives on the hand, how light moves through a stone, and how metal carries weight day after day. Working collaboratively with each client in our calm, focused showroom, we offer private appointments to give every project the attention it deserves. Whether you're designing a custom engagement ring, repurposing a cherished heirloom, or seeking expert jewelry repair, Alloy is committed to delivering exceptional craftsmanship and a deeply personal experience.

Engagement rings are the heart of our business and we take pride in helping craft a ring that will represent your love story and last a lifetime. We have a large selection of engagement ring styles in stock at all times and can work with you to design a fully custom engagement ring as well.

Our 3D ring builder is the best of both worlds — you get to design a fully custom ring and we can have it ready for you in just a couple of weeks at a great price, fully customized around your center stone.
