Sell Your Jewelry for More with Diamond Banc’s Seller’s Agent Service

We actively market your jewelry to a national audience to ensure it reaches the right buyers. Once your piece is sold, you receive the preferred selling price that was initially agreed upon. Our team manages every aspect of the process to enhance your jewelry’s value, presentation, and appeal before it goes to market. This approach aligns our goals — maximizing the value of your jewelry. We are only compensated once your item is successfully sold.

Maximize Your Earnings

Earn up to 15% more than our immediate purchase offer for your jewelry.

Receive an interest-free advance of up to 50% of our original purchase offer, up to $25,000.

Selling Timeline & Terms

• 20-business-day selling window to reach the target proceeds.
• If your item doesn’t sell within 20 days, you have until day 30 to repay the advance.
• If the advance isn’t repaid by day 30, ownership transfers to Diamond Banc, and the remaining balance of our original purchase offer will be paid to you within 5 business days.

Nationwide Marketing Strategy

We implement an exclusive nationwide marketing strategy that prominently showcases your jewelry on multiple platforms and among a network of qualified buyers. Throughout this process, we maintain the highest level of confidentiality regarding our clients’ identities.

The Sellers Agent Service

Selling your jewelry is an important decision, and our Sellers Agent Service is specifically designed to help you achieve the maximum possible return on your item.

Eligibility Requirements

• Item verification protocols must be completed before seller advance funds are released.
• The Seller’s Agent program applies to items valued at $5,000 or more.

What Sets Diamond Banc Apart from Traditional Consignment Options?

When you entrust your jewelry to us, we act as your dedicated sellers’ agent. Our experienced team uses a comprehensive marketing strategy to showcase your jewelry across multiple platforms and connect with a broad network of qualified buyers. This ensures exceptional exposure and helps you achieve the highest possible selling price.

We understand that your goal is a successful sale and prompt payment. While many consignment services make bold promises about high returns, the reality is often disappointing, with unsold pieces and consignors waiting for results that never come.

At Diamond Banc, our focus is on results, not rhetoric. We lead with integrity and apply a modern, data-driven approach to jewelry marketing. Our team invests time, resources, and expertise to ensure your item is positioned for success. Because our compensation depends on your success, our goals are completely aligned with yours.

When evaluating potential consignees, it is important to ask the right questions. The division of profits matters little if the consignee cannot achieve an acceptable sale price or, more importantly, complete a successful transaction. Many consignors assume a quick and profitable sale, only to be disappointed later.

Choose Diamond Banc as your trusted jewelry consignee and experience how our Sellers Agent Service turns potential into profit. Do not settle for empty promises. Work with a team that values transparency, delivers consistent results, and is dedicated to achieving the maximum return on your jewelry.

Contact Diamond Banc today to learn more about how our service can help you unlock the full financial potential of your fine jewelry.

A Partnership Centered on Shared Success

From the start, Diamond Banc works with you to establish your preferred selling price and align every step with your goals. You never pay a fee until your jewelry sells—ensuring our motivation is entirely focused on maximizing your return. This performance-based model means our success depends on achieving the best outcome for you.

Expert Marketing & Complete Consignment Management

Selling your fine jewelry should be effortless and rewarding. Our experienced team manages every step—from authentication and professional photography to listing and negotiation. We market your item across the most reputable national and industry-specific platforms, connecting directly with verified jewelry buyers and jewelry collectors. Our goal isn’t just visibility—it’s real, measurable results. Every detail is handled with precision, care, and confidentiality.

Access Funds Before Your Item Sells

Need cash quickly while your item is being marketed? Diamond Banc offers interest-free advances of up to 50% of your estimated proceeds. When your item sells, you receive the balance immediately. If your piece doesn’t sell within the initial timeframe, you have flexible options to either repay the advance or continue under updated terms—always with transparency and clear communication.

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.

I absolutely will continue to patronize Diamond Banc and will highly recommend for their excellent service.
