FAQs

A clear and comprehensive agreement sets expectations and protects both parties throughout the consignment process.

Merely displaying your jewelry in a case or placing it on a website is not sufficient in today’s competitive market. Look for a consignor who demonstrates a strategic marketing approach to maximize exposure and increase the chances of a successful sale.

Insurance coverage is crucial to protect your jewelry from unforeseen circumstances. Ensure that the consignor offers adequate insurance coverage and understands the importance of safeguarding your valuable item.

While specific timelines may vary, it’s important to have a general understanding of the consignor’s expected timeframe. This will help manage your expectations and ensure a timely sale and payment process.

What Sets Diamond Banc Apart from Traditional Consignment Options?

When you entrust your diamond to us, we become your dedicated sellers’ agent. Our experienced team employs a comprehensive strategy to market your diamond across various platforms, connecting with a vast pool of potential buyers. This gives your diamond unparalleled exposure, maximizing its sale value.

We understand that your primary goal is to secure a successful sale and receive prompt payment. While many consignment sellers may promise high returns and boast of lofty selling prices, the reality can often be disappointing, with many diamonds remaining unsold and consignors left without payment.

At Diamond Banc, we believe actions speak louder than words. We prioritize integrity and embrace a modern, innovative approach to marketing your diamond. By investing our time and resources, we are committed to ensuring its successful sale. By aligning our interests with yours, you can trust us to strive for the maximum return on your investment.

When searching for a potential consignee, it’s crucial to ask the right questions. Focusing solely on the cut of the profits is irrelevant if the consignee cannot deliver an agreeable selling price or, more importantly, ensure a successful sale. Unfortunately, assumptions of a successful sale are all too common, often leading to disappointment.

Choose Diamond Banc as your trusted consignor, and experience the difference our Sellers Agent Service can make. Let us transform your diamond into its maximum return. Don’t settle for empty promises—rely on a consignor with a proven track record, a commitment to transparency, and a genuine dedication to achieving successful sales.

Contact Diamond Banc today to explore the possibilities and discover the financial potential of consigning your diamonds with us.

3 Must-Haves When Consigning a Diamond

When considering where to consign your diamond, there are three essential factors you should prioritize. These must-haves ensure a successful and rewarding consignment experience:

Laser Inscription & GIA Certification:

For a natural diamond to be sellable, it must have a laser inscription and be GIA-accredited. This provides authenticity and adds value to your diamond. If your diamond does not possess these attributes, a reputable consignor should quickly offer to facilitate the process for you. Without proper certification and laser inscription, proceed with caution.

Standardized Consignment Agreement:

A standardized consignment agreement is crucial to establish clear terms and protect both parties involved. This agreement should outline important details such as the insurance value of your diamond, payment terms, any applicable fees, and the protocol for retrieving your item. Reviewing and understanding this agreement is vital to ensure a smooth consignment process.

Confidence in the Consignor:

When entrusting your treasured diamond to a consignor, it is essential to have confidence in their expertise, integrity, clientele, energy, and drive to turn your item into a check in your hand. Just as you would hesitate to leave your valued possessions with just anyone, a consignor in the jewelry business should inspire trust. Ask hard questions and seek answers that provide you with the assurance you need to make the right decision.

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 diamond 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.

What Clients Are Saying…

My experience with Diamond Banc was deeply satisfying as the people, especially Cade, the agent who helped me through the process, sincerely valued the kind of service they are providing to their clients. There was lingering skepticism on my part as I’ve never secured a loan before using my precious metals as collateral. Nonetheless, just right before signing the contract, Cade and his director (my apologies as I forgot his name, if he had mentioned it) gave me the assurance that their company is genuinely committed to provide excellent service. I will definitely recommend Diamond Banc as a go-to company to source funding using gold bullion as collateral. Furthermore, I’m sure I will consider Diamond Banc for future transactions.

For the first time in my life I had some jewelry to sell. I didn't know anything about it, what it really was, or what it was worth. I did some research online and discovered the Diamond Banc. I researched them to make sure they were legit and a good place to deal with. I read the reviews, they all sounded good. A+ with BBB. Appeared to be very reputable. I made an appointment, got there 45 mins early. Was offered a drink and a comfy chair! I had 3 people check on me while I was waiting. Very nice and polite people. When my appointment time came I was introduced to Christine. I was worried that I would be met by some smug uptight fancy pants that would probably treat me like a peasant and tell me my jewelry was junk. ABSOLUTELY NOT! Christine was a real human just like me! Very nice, polite, funny, and informative! That girl was top notch on her work. She went over the jewelry and explained everything in a way that anyone could understand. She was very funny and so laid back! A very welcome person to find walking into a fancy place like that. We came to an agreement on the jewelry and had a nice conversation about whatever came to mind. If I ever have anything to sell again I will definitely go back! Very fair, friendly, and informative. My experience there was A+++.

Miguel Rodriguez, Director of Diamond Banc of Scottsdale. He’s not only a phenomenal person but in awe of his expertise and knowledge of diamonds, gold and silver. He went way over in time for us to explain every detail of my diamonds and showed me all the testing that they do. I was amazed at how technical it is. He gave us an extremely fair price on my jewelry and I left extremely happy person. I can highly recommend him. My husband and I enjoyed his company and would gladly return if we ever need his expertise again..

Selling diamond rings online can feel like massive leap of faith, so naturally I was very nervous about the process. However, this company completely exceeded my expectations. They were super accommodating, answered all of my questions thoroughly, and immediately resolved a minor trust concern I had early on, which completely put my mind at ease. On top of that, the payment was deposited into my account the very next morning, as promised! Special thanks to Jordan and Cade who were both easy to talk to and made the entire experience seamless. I highly recommend Diamond Banc
