I’ve been to Diamond Banc three times now, and every experience has been outstanding. Ethan has been honest, transparent, and professional from the very beginning. He takes the time to explain everything in detail, answers every question without making you feel rushed, and never pressures you into making a decision. That level of honesty is hard to find these days. What keeps bringing me back is the consistency. Every visit has been smooth, comfortable, and straightforward, and I’ve always felt like I was getting a fair deal. It’s clear that Ethan genuinely cares about building trust rather than just making a transaction. If you’re looking to sell jewelry or a watch and want to work with someone who’s knowledgeable, respectful, and trustworthy, I can’t recommend Ethan and Diamond Banc enough. After three great experiences, I wouldn’t go anywhere else. Highly recommend.
Response from the owner:Thank you so much for your thoughtful 5-star review! We truly appreciate you taking the time to share your experience. We’re so happy to hear that Ethan has consistently provided honest, transparent, and professional service each time you’ve visited Diamond Banc. Building trust and making our clients feel comfortable is always our priority, and your kind words mean a lot to our team. We sincerely appreciate your continued business and recommendation!

I met with Ethan this morning. I must admit I didn’t know what to expect. I’ve never sold a watch before and I didn’t know what to expect. I was afraid to walk into a seedy back room with watch hustlers. Instead, Ethan was professional, polite and knowledgeable. He pointed out the good and the bad of my watch, which I already knew but appreciated his honest demeanor. We worked out a price that was fair and I was very pleased. I walked out with a check that morning. The process was so painless and pleasant, I only wished they bought and sold cars too. Keep up the good work!
Response from the owner:Thank you for sharing this, we truly appreciate you taking the time. I’m glad Ethan was able to provide a professional, transparent, and comfortable experience from start to finish. That’s exactly what we aim for!

Response from the owner:Thank you, Scott! We appreciate your continued trust in Diamond Banc and are glad to hear about your positive experiences with Ethan and our team. Your recommendation means a lot to us!
