Hello, I’m Carl Blackburn, a custom jewelry designer working with couples throughout Oceanside and the greater San Diego area. For more than three decades, I’ve helped people create engagement rings that feel deeply personal — rings designed around your ideas, your style, and the life you’re building together. In many jewelry stores, you work with a salesperson. Here, you work directly with me — the person designing your ring. I guide you through every step of the process, from the first conversation and CAD illustrations to the final handcrafted piece. The goal is simple: to create a ring that feels unmistakably yours. Below are a few examples of engagement rings created for past clients. Each one began with a conversation.

Oceanside carries a distinct kind of coastal character—less polished, more lived-in, with a mix of historic charm, surf culture, and a steady creative resurgence shaping its identity. The iconic pier stretches into the Pacific as both a landmark and a daily backdrop, while the harbor, local markets, and emerging food scene give the city a sense of movement and renewal. It’s a place where couples often find themselves thinking less about convention and more about what feels genuine to them.

That mindset naturally carries into how they approach something as meaningful as an engagement ring. Rather than selecting from what’s expected, many are drawn to the idea of creating something that reflects their story, their pace, and the life they’re building together. The process becomes less about the purchase and more about the experience itself.

Working from his San Diego boutique, Carl Blackburn partners closely with Oceanside couples to bring that vision to life. Each project begins with a conversation and evolves through a collaborative design process that prioritizes comfort, craftsmanship, and individuality—resulting in a ring that feels personal from the very first sketch to the moment it’s worn.
