Hello, I’m Carl Blackburn, a custom jewelry designer working with couples throughout Rancho Santa Fe 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.
