How does the transaction work?

There are two ways you can work with Diamond Banc to get a loan secured by your fine jewelry, diamonds, & watches:

  1. If you are looking to receive an immediate offer & same-day funding, we encourage you to visit one of our offices nationwide. Schedule an appointment at a Diamond Banc location near you, have your jewelry evaluated on the spot, and get paid immediately. Typically, this process takes less than 40 minutes.
  2. Fill out our online submission form above & receive a quote within 24 hours from one of our expert diamond buyers. Our team will provide you with a fully-insured shipping label to mail your diamond to our headquarters. From the moment your diamond arrives at our headquarters, it remains on continuous video surveillance until the package is opened and your items are verified. If you accept our offer, payment will be issued immediately via wire transfer. If you elect not to accept our offer, your diamond is expedited back to you with a fully-insured shipping label.

What is the minimum and maximum amount of money I can get?

Diamond Banc regularly makes loans from $500-$250,000+ secured by fine jewelry, diamonds, and watches. Our loan offers are based on the liquid wholesale value of your item.

To learn more about our Jewelry Equity Loans & how we determine how much your item is worth, watch this video from our founder, Mills Menser.

How long does it take to fund the transaction?

In most cases, transactions are funded same-day via check or wire transfer.

Do I have to make monthly payments?

Yes. You will be required to make monthly interest payments during the duration of your loan. If you elect to make a payment larger than your minimum monthly interest payment, that amount will be applied toward your principal balance. 

Do you provide insurance?

Yes. Your items are fully insured while in our possession.

Will defaulting on my loan affect my credit score?

No. Diamond Banc does not report to any credit bureaus. Our loans are completely confidential. In the event the borrower elects not to repay their loan, there is no negative recourse to the borrower outside of surrendering ownership of the pledged collateral.

 How is my item stored and secured?

All assets are stored on-site in one of our state-of-the-art, alarm-protected, 24-hour security-monitored, fireproof vaults. Your items are fully insured while in our possession.

How long do I have to make payments?

Diamond Banc offers 30-day loans that can be extended for as many 30-day periods as the client needs. There is no minimum loan period, as our loans can be paid off in full at any time without penalty.

Beautiful storefront, just be aware you need to park on 7 and take the elevator to the bottom floor then sign in and take the elevator to 11. Xamoney met me at the entrance and showed me to her office.

Aventura’s #1 Jewelry Equity Lender

What sets Diamond Banc’s jewelry equity loan program apart is its flexibility and ease of access. The process is straightforward and streamlined, with minimal paperwork, and no credit checks or income verification required.

Once you accept the loan offer, loan documents are signed, and your jewelry is securely stored. You will receive your funding via wire transfer or via check, typically within the same day.
