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