san francisco custom engagement rings,
served fresh daily
At Gem Breakfast, we design one-of-a-kind custom engagement rings right here in San Francisco. Our custom rings are for people looking for a marriage of bold design and exceptional quality.
We’ve been in business 8+ years and known for our ingenuity of design, unique stone selection and unmatched quality. Here there are no mass-produced menus, just small-batch fine jewelry crafted to your taste.
Whether you’re dreaming up a sleek solitaire, a vintage-inspired halo, or a ring that looks like it fell out of a starburst, our San Francisco showroom is where your imagination meets real gold, rare diamonds, and the world’s most unique gemstones.
Because you want something real, bespoke to you, and wrapped in details and meaning. We don’t do boring factory-made rings and to us “customized” isn’t by checking a checkbox.
We keep it small, intentional, and personal. You work directly with Chef Cat or Chef Sara and watch your ring go from concept to finished.
Our appointment-only showroom is in downtown San Francisco and is the beating heart of our jewelry kitchen. Come by for a private consultation, see our stones in person, and sip something sparkling while we design your dream ring together.
