FAQs
Do you have a standardized consignment agreement for my review?
A clear and comprehensive agreement sets expectations and protects both parties throughout the consignment process.
What proactive steps and investments will you make to actively market my item?
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.
How long do you envision it taking to sell my item and get me paid?
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.

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.

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.

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.
