We regularly work with pieces from David Yurman, Cartier, Tiffany & Co., and Van Cleef & Arpels. On the watch side, our buyers are just as comfortable authenticating Rolex, Omega, Tudor, and Patek Philippe.

Before you sell or borrow, it helps to know exactly what you have. Our team also provides jewelry appraisals and estate jewelry appraisals, so you walk in with a clear, documented sense of value.

To sell your jewelry for the most money, work with a professional jewelry buyer who understands current market demand for diamonds, designer pieces, gold, and luxury watches. Avoid places that only pay based on scrap value. At Diamond Banc, our experts evaluate your item’s diamond quality, brand, condition, and global resale demand — not just its metal weight. Because we sell to a nationwide and international network of dealers and end buyers, we’re able to offer stronger, market-driven prices compared to typical local buyers.
The highest payouts typically come from established jewelry buyers with access to large resale networks rather than small retail stores or pawn shops. Diamond Banc is a nationwide jewelry buyer that competes in real-time markets, which allows us to make aggressive offers on diamond engagement rings, loose diamonds, Rolex watches, and designer jewelry. Our buying power and data-driven evaluations often result in higher offers than traditional “cash for gold” businesses.
The best place to sell your jewelry is with a reputable, transparent jewelry buyer that specializes in high-value pieces. Diamond Banc provides private, no-pressure evaluations in a professional office setting — not a retail counter or pawn environment.
It depends on your financial goals. If you no longer want the item and want the highest immediate payout, selling is often the better option. If you prefer to access short-term liquidity but keep ownership, a jewelry equity loan may be ideal.
The best local option is a specialized diamond buyer with professional grading expertise. Diamond Banc evaluates diamond rings based on cut, color, clarity, carat weight, certification, brand, and overall market demand.
