Clients love working with Diamond Banc based on the transparency and guidance that we deliver.
We show you wholesale comparable diamonds to yours, what dealers are asking for them, and what dealers are selling them for and we show you this on the largest dealer-to-dealer trading platform in the world. We explain why we’re making the offer that we’re making, and allow you to understand that you’re truly getting the most they can for your diamond.
Our ultimate goal is to ensure you feel confident in your decision to sell your diamond by providing you with the transparent diamond education you deserve.
Once you accept our purchase offer, we issue payment via check or wire transfer immediately.
Bring any original documentation you have for your diamond, such as GIA or other grading reports, purchase receipts, and previous appraisals. While documentation can help streamline the evaluation process and potentially strengthen your offer, it is not required. Diamond Banc’s experts can evaluate your diamond on-site using professional gemological equipment.
Yes. Diamond Banc purchases certified and non-certified diamonds. While a grading report from GIA or another major lab can enhance value and buyer confidence, Diamond Banc’s experienced diamond buyers perform a comprehensive in-house evaluation to accurately assess quality, authenticity, and market demand.
Diamond Banc buys a wide range of diamond shapes including round brilliant, oval, cushion, emerald, princess, radiant, pear, marquise, and more. The company specializes in diamonds 0.75 carats and larger, with particularly strong demand for 1.00 carat and above stones. Larger diamonds and high-quality stones typically command the most competitive offers.
Diamond Banc determines pricing based on current global diamond market conditions, not outdated retail pricing. Each diamond is evaluated according to the 4 Cs—cut, color, clarity, and carat weight—along with factors such as fluorescence, certification, and overall market demand. By leveraging real-time wholesale data and an extensive network of buyers, Diamond Banc provides competitive, transparent offers.
At this time, Diamond Banc does not purchase lab-grown diamonds. The secondary market for lab-created stones is highly volatile and limited compared to natural diamonds. Diamond Banc specializes in buying natural diamonds and fine jewelry, where there is strong and consistent global resale demand. If you are unsure whether your diamond is natural or lab-grown, Diamond Banc can help determine this during your evaluation.
Some local jewelers may buy diamonds, but many primarily focus on selling new inventory rather than purchasing from the public. Traditional jewelry stores often make conservative offers since buying pre-owned diamonds is not their core business model. Diamond Banc specializes in buying diamonds directly from consumers, leveraging a national network of professional buyers and real-time market data to provide stronger, more competitive offers.
You can sell your diamond through several channels, including local jewelers, pawn shops, online marketplaces, auctions, or specialized diamond buyers. For the strongest combination of security, speed, and value, working with a professional diamond buying firm like Diamond Banc is typically the most efficient option. Diamond Banc provides a complimentary evaluation, explains how your diamond is valued, and presents a transparent offer with no obligation to sell.
If you’re searching for a trusted place to sell your diamond, Diamond Banc has locations across the country in major metropolitan markets. With private offices nationwide, Diamond Banc combines national buying power with local, personalized service. Clients benefit from in-person consultations, secure transactions, and immediate funding options—all backed by a company that specializes exclusively in buying high-value diamonds and fine jewelry.
Diamond values depend heavily on quality, size, and current market demand. While certain high-quality and larger natural diamonds have remained strong or appreciated over time, the overall diamond market has experienced fluctuations due to global supply, economic conditions, and the growth of lab-created stones. The best way to determine your diamond’s current value is through a professional evaluation with a specialized buyer like Diamond Banc, who bases offers on real-time wholesale market data.
Online marketplaces can provide exposure, but they often come with listing fees, commission costs, shipping risks, and uncertain timelines. Many sellers find that working directly with a professional diamond buyer like Diamond Banc offers a more secure and predictable experience. Diamond Banc provides both in-person and remote selling options, allowing clients to receive a professional evaluation and competitive offer without the uncertainty of managing a private sale.
The best price typically comes from working with a buyer who understands the wholesale diamond market and has access to active resale channels. Diamond Banc evaluates diamonds based on current global demand and competitive wholesale pricing—not outdated retail appraisals. By specializing in larger, high-quality natural diamonds, Diamond Banc is able to present strong, data-driven offers designed to maximize client returns.
Yes. Diamond Banc offers immediate payment once an offer is accepted. After completing the evaluation and finalizing the agreement, clients can receive funds the same day via wire transfer or other secure payment methods. The process is confidential, streamlined, and designed to provide both convenience and peace of mind.
