Our experience with Diamond Banc was very positive. The process was as secure as possible, the information was timely and accurate, pricing was fair based upon wholesale market factors, and it was executed smoothly. We would happily do business with them again.

Worked with Mia to sell an engagement ring. It only took a few minutes for the appointment and they gave me a great price. Much better than trying to sell on marketplace etc.

I went to Diamond Banc to sell my wedding ring, and Mia immediately offered me the best market price. I didn’t even need to visit any other jewelry buyers. She was incredibly sweet, friendly, and made the whole process easy and comfortable.
Excellent to work with! I will always work with them
Work with Mia on a ring I never wear anymore. Gave me a super deal. I would definitely check out Diamond Banc if you have a old ring that’s valuable and want the best deal in town.
Smooth and easy transaction.
I think they were fair, And everything was done right there in front of me. And Great service…
Mia was amazing! We went in to sell a few pieces of jewelry for what we expected to be a small amount of money. We walked out with a large check in hand! The process was seamless and simple. Don’t sell your gold to a pawnshop! Sell it to Diamond Banc!!
Diamond Banc responded quickly, and the process was quick and easy. I had a great experience, and I will be returning. I recommend Diamond Banc!
I had a wonderful experience selling some jewelry pieces with Diamond Banc. Mia was informative and fast. I was in and out with a check in under 30 minutes.
The process was very quick and seamlessly easily and the staff are very friendly! Highly recommend.
I don’t have a lot of experience selling higher valued personal items and when I have it’s always been private sales or just a quick pawn shop stop. However I had a nice 14k gold necklace I’ve had for a couple decades that had a broken clasp and wasn’t my style anymore so I made the decision to sell it. Did some research and found this company and I kid you not it was so simple and kept the icy corporate sales feel out it. Mia is super personable, knowledgeable, and efficient. I had an email quote and same day appointment set up within an hour of my inquiry, went to office, had my appointment which took about 15-20 min since I did the quote ahead of time and I walked out with my check. Will be going back for any future sales I plan to make involving jewelry or precious metals. They absolutely deserve the 5 star ratings they receive.
Lyndsey was very helpful and knowledgeable about the ring I was selling. She explained in detail how they came up with their offer for the ring. The offer was fair and higher than any of the other places I went to.
Schedule a meeting with Mia. She was very informative. Explained the market very well and gave me a great price for my jewelry. I was very pleased with the experience and service.
Mia made the entire process from booking the appointment to walking out the door easy as pie!!!! Took her card to tell all my friends & if I need to sell some more pieces! 10 outta 10 recommend
Mia was such a pleasure to work with!!!! Professional, passionate, and dedicated to her craft. Diamond Banc is lucky to have her!
Mia was GREAT to work with! Great with customer service and very personable!! Bought my 14K gold Diamond ring for a good price!!!
Mia was so nice! She was very polite and very kind
Very good experience. Fast and professional.
Meeting with Mia Cossey was an absolute pleasure. Very knowledgeable and honest with additional advice on related matters. I will definitely return.
I had such a pleasant experience working with Mya! She was quick , efficient and very fair with her offer! Diamond Banc has earned a life long customer.
I recently sold a watch. Lyndsey was very polite, knowledgeable and quick. I feel I received a fair price for my item. I recommend Diamond Banc and will return in the future.
My experience was very pleasant and relaxing. I left feeling completely comfortable with my decision. Thank you for your help.
Professional, trustworthy service. I would use them again without hesitation.
Easy to work with Diamond Banc had many pieces went as professional as it could. With rarities, Scotsman and others found not as nice to deal with.
Quick and easy process with great value transaction
I had an absolutely fabulous experience here. Mia is amazing and super knowledgeable and helpful. I felt like I got an amazing deal for what I brought in and she was quick, polite, and super friendly. Definitely recommend 10/10. I will be going here for all my future jewelry sales.
I recently had the privilege of selling a diamond that I had inherited from my late brother. I was a bit skeptical, being this was my first diamond sell. Mia was extremely welcoming and made the process very easy and comfortable. I was able to share the story of my late brother and how I came in possession of such a great gift. She was warm and welcoming and offered her condolences. She made the atmosphere feel less business like and more personalized. I absolutely will continue to patronize Diamond Banc and will highly recommend for their excellent service.
Very good experience!
Transaction was handled professionally and courteously. Correspondence was prompt and meeting efficiently conducted. Highly recommend dealing with this business
Very professional service and super friendly people with big smiles !
I had good experience with you and enjoyed my self you have a nice office it was fun thank you
They were awesome helping me with some jewelry I had to see if they were worth anything and helped me with a watch if it was fake or not. They were AWESOME!! In every thing.
Mia (Lindsey) was very professional and informative during the entire process.
Excellent customer service! Everything went so quick and smooth. They were very kind and patient with us even when we brought our tired and fussy toddler to our. A appointment.
