Very knowledgeable and honest business. As a test I let them analyze my earring from Kay's, and he accurately gauged the price. If you're interested in jewlery and in the Bay Area, you're only cheating yourself by not reaching out here first. Don't go to Kay's or a store in your local mall, 66Mint first, then make a decision from there. But you'll decide with 66. I'll bet money on it at this point.

I had an amazing experience with Marcus from beginning to end! I learned so much thanks to him educating me as well! My fiancé is in LOVE with her ring! Everyone should shop 66 mint!!!

I am not someone that is excited about shopping for jewelry... and I was definitely feeling anxious about shopping for an engagement ring. Marcus made the experience SO much better. He's just a good human being. You get a really good feeling from him, and everything you experience really reinforces that good feeling. He is an honest person, who cares about people, and his customers. Another thought: I was a little worried about going to a small business jeweler rather than a bigger shop. I felt a little intimidated to understand exactly how ring shopping works, and what all the letters mean when it comes to diamonds. Marcus was SO PATIENT with all of my questions. Honestly, he made the experience enjoyable. He also mentioned that the business was started by his great-grandfather and it's really nice to support a long-standing small business. We'd live in a better world if we all support small businesses more often!

A wonderful experience having our family’s jewelry appraised. From making an appointment to determined value, I’d recommend 66 Mint when you want a honest appraisal.

Absolutely over the moon with my ring and so is my fiancé. Excellent service from the top to bottom with 66mint. I got exactly what I wanted and was even able to help create it. Great communication done completely on schedule with zero hiccups. I would highly recommend 66mint and trust them that you’re getting exactly what you’re searching for. Thank you 66mint

Dealt in person with Marcus to sell estate jewelry. He was professional. candid and offered a fair price. Recommend him without question.

Marcus and his team are super responsive and helpful! Nothing but great experiences with 66Mint

I had a wonderful experience here. Marcus was responsive, friendly, and transparent from the time I contacted him till we completed the sale. He took the time to explain how he came up with his offer and offered a very fair price. Not your typical brick and mortar experience. He’s very professional and honest, all the things you would want in a personal jeweler. What a great find this was!

Marcus is wonderful. We got personalized, excellent service and perspectives. No pressure to buy or upsell, just expert guidance based on the info we provided. Plus, he’s very kind, responsive, professional, and can give you some pointers on local surf to boot!

I couldn’t be happier with my purchase! The entire experience working with 66mint was so easy. The photos & details on the website helped me decide which earrings I wanted. I was a bit nervous to buy fine jewelry without seeing it in person but decided if it wasn’t exactly what was pictured online I could send it back. I purchased my earrings on Tuesday and I’m wearing them on Thursday morning. They are better and more beautiful than I expected! They were packaged very securely and arrived with a handwritten note thanking me for buying from 66mint. That was an unexpected personal touch and I wouldn’t hesitate to order again from 66mint.

Excellent experience! I am very satisfied and pleased with my purchase. The customer service was top notch. I am a very nervous buyer and since this was a significant purchase of an item that I could not hold or examine in person, I was even more anxious. I asked many questions which were all promptly answered via text. I had been searching the internet for months and had visited some local jewelers. One jewelry chain even had rubies of similar size sent in so that I could build my own ring but they were very poor quality (heavily included and dark in color) and the cost of just a single loose ruby was more than the price of the ruby and diamond ring that I purchased. My ring is gorgeous! I will absolutely shop with them again!

My family has been buying jewelry from Marcus at 66 Mint for a very long time now, and I cannot speak higher about my most recent experience selecting an engagement ring for my now-fiancee. This was no small decision, and we even switched directions a couple times! Marcus was incredibly patient throughout, and is a true professional - he was kind, informative, and super responsive. If you are looking for gorgeous, unique pieces of jewelry look no further. Whether it's a generational ring with tons of history, or an entirely custom approach, Marcus has you covered with a ton of knowledge and expertise when it comes to fine jewelry. On top of this, the entire experience going downtown to his building was really fun, there's a thread of old school San Francisco that is alive and well at 66 Mint. I cannot recommend this business higher, and will undoubtedly be returning for future jewelry needs. Thank you so much!

Great selection of one of a kind rings! Marcus was very knowledgeable, patient, and not pushy when it came to choosing an engagement ring. Just the experience I was looking for. We look forward to designing our own wedding bands here. Come and support this family owned SF business that’s been around 100+ years!

Everything about my experience with 66Mint was amazing. I came with my younger daughter and she was warmly welcomed. I was looking for a specific piece and their communication and customer service about it was excellent, prompt and accommodating. As for their quality: just beautiful. When people see my purchase I always have the same response: stunning. I will definitely be returning.
