I bought a custom engagement ring, without really knowing anything about rings. Cat was super helpful in turning the few things I knew my then girlfriend cared about into the perfect ring to propose with. She was also super responsive during the process and took timing constraints really seriously.

Our experience with gem breakfast was wonderful. We were looking to create a custom engagement ring, and initially booked an appointment to come to the showroom to see a few rings we were interested in. When we were ready to take the next step, we went through the custom process with Sara. From stone selection to discussing the setting, details, and engravings, she helped us navigate through it step by step, while providing us with helpful suggestions and support along the way. We were nervous, but Sara was so patient and encouraging the entire time, and she even helped my fiancé keep the proposal a surprise for me at the end. We appreciate and are so grateful to her and everyone at GB who worked on our engagement ring stack — the final result was stunning and we would be more than happy to work with them again.

I'm obsessed with my celeste Zaha!!! A collaboration piece of my dreams between two bad ass women designers, with tons of old mine diamonds omgggg. Basically its perfect and comfortable in every way :D

Beautiful rings! I purchased the Celeste Rising Star Engraved Diamond Gold and Solstice Engraved Celestial Gold Bands and they both arrived right on time. The rings are gorgeous and exactly what I wanted. Thank you for working with me!

I had such a great experience from ordering to receiving my order. Thank you, Alyssa and the team.

My best friend and I got matching GB rings and I couldn’t be happier. The GB team was so responsive, kind, and genuinely excited to deliver our order. The rings themselves are incredible and I can’t wait to eventually get my own custom! Thank you to the GB team for putting a smile on my face every time I look at my ring.

I worked with Cat and Sara to create a custom engagement ring, and the process couldn't be any better. - Cat and Sara initiated the collaboration by hopping on the phone to walk me through the process as well as to translate my unorganized thoughts into an actual blueprint for a ring. - At every step of the process, I was given a perfect variety of options across different prices and design choices, allowing me to make decisions fully aware of the tradeoffs. - I always had transparent certainty of the ring's development with ghost hand mock-ups, CAD renderings, and 3D resin prints. - All of my silly, dumb, or panic-driven questions were professionally, compassionately, and sufficiently answered. - All of my hopes for this ring came true, and I am forever grateful to these SF-local experts making our SF-native relationship so happy.

I had an emergency request to get a stone on a deadline and Alyssa worked with me on every step of the way to get me the diamond by when I needed it. Couldn’t be be happier and can’t thank Alyssa and the team enough!! Highly recommended!!

I ordered a Celeste Major with Citrines & Pink Sapphires in peach gold. It is absolutely beautiful.

Another masterpiece from the GB kitchen 👏🏼🎉 I fell in love with a neon pink sapphire in a loose gem sale post and Cat and my husband made the Barbie ring of my dreams as an anniversary present. She is sassy, she is cute and she is BOLD 💖✨ Cat is a wizard. A Michelin gem chef. A magical being with endless ideas. The entire process is so fun and simple, but your results will be anything but 👏🏼

My fiancé and I worked with Gem Breakfast on a custom engagement ring. I absolutely loved the asymmetrical rings, which Sara used as a starting point for the design. The process of choosing a stone and working with Sara on the settings, side stone placement, and band engravings was so fun and collaborative. The end result was a ring so unique, stunning, and so much more meaningful than buying a generic ring from a large retailer. I also really love GB’s philosophy on engagement/custom rings — not needing to have a traditional diamond ring for an engagement, partners having a say on the ring they’ll be wearing, being able to change the ring if styles change, and treating yourself to a gorgeous ring if you’re feeling it! I would highly recommend working with the amazing Gem Breakfast team.

Wonderful creative process where they really worked with me to find an arrangement I was excited about and delivered just as pictured and described! A real joy to work with and so happy with my ring!

I wanted a one-of-a-kind engagement ring, and the team delivered! They were kind and informative every step of the way, and even though it was my first time really dealing with jewelry at all, they helped me make the best decision every step of the way. She loved the ring and everyone she's shown it to loves it too! I'm so glad I worked with Gem Breakfast to help me through such an important part of my life!

I recently lost one half of a pair of earrings that I usually wear in my second piercing. It was the perfect time to order a pair of Nova Diamond Star Earrings. They are lightweight, but take up a decent amount of space on the lobe and look very sweet.

We had a wonderful experience designing a custom engagement ring with Gem Breakfast! Our initial design session was with Cat, who showed us a ton of options in their adorable showroom. She helped size me and discuss all the things we did and didn’t want. We then worked with Sara to narrow down our stones and design. The whole process was really clear and fun, and the end result is an absolutely perfect ring! A cat face is cut out behind the sapphire :) Would definitely work with them again and highly recommend them to anyone interested in a custom ring design!

Three times working with GB now, and three equally amazing experiences. Sara and the entire GB team are unmatched in the care, dedication, and communication they put into each and every project! My inspiration was a laurel wreath, as I incorporated quotes from “The Song of Achilles” into my wedding vows, and the ring captures its essence perfectly! Smooth, subtle, yet intricate the closer you look at it. I can’t sing their praises highly enough!

I fell in love with the Celeste ring the minute I saw it! When I reached out with questions, the team sent a video comparing each version of the ring and I ended up choosing the Celeste Major! I wear it 24/7 and admire it all the time! Highly recommend :)

I love these 14k diamond studs. They are so sparkly, comfortable, and perfect for my 2nd and 3rd piercing . Packaging is so pretty too! Can’t wait to purchase a ring 👀🥳 thanks GemBreakfast:)

I loveee my Celeste Major ring!! The GB team answered all my questions and made the process so seamless. The ring is unique and detailed while being extremely wearable, comfortable, and fitting seamlessly with any stack. Even when I got the wrong size (my own fault) the team was so responsive and offered to work with me on a resize. The customer service is superb and I would buy again and again!

I’ve always admired Gem Breakfast’s fun, playful aesthetic and cool designs. When I saw they were offering a limited batch of antique/omc lab diamonds, I jumped at the chance to snag an oval (I rarely see antique-cut ovals). Then I worked with the lovely Alyssa to customize a simple bezel-set ring in 14k unplated white gold. This isn’t my main ering, but I find myself reaching for it more than my original!
