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-certified. 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.
