Great service thank you!
Bob Van M.
My experience with Xammany was excellent. I had many small pieces and she took the time to test every piece for authenticity. When we finished we agreed on a price and I was issued a check on the spot. I thoroughly enjoyed my experience and if you need your jewelry appraised for a more than fair evaluation I would highly recommend Xammany and her services. Very happy with my results.
Xavier L.

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.

The Diamond Banc Pawn Loan Difference

  • HIGHEST LOAN OFFERS |  The more a lender specializes in jewelry, the more they can offer for your items. Pawn shops take a wide range of items on collateral such as golf clubs, power tools, electronics, etc. In contrast, Diamond Banc offers pawn loans in their area of expertise: jewelry, watches, diamonds, and precious metals. We specialize and focus on one area of pawn loans, enabling us to offer the maximum amount. Our jewelry experts have been in the industry for decades and complete continuous training and education courses to recognize every value-adding factor when evaluating your items, to maximize your loan pawn amount. David, our local Miami FL Market Director is an expert with a decade of experience in fine luxury jewelry and specializing in watches. David’s extensive training and knowledge allow her to provide the maximum jewelry pawn loan offers in Miami.  
  • CREDIT LINE FLEXIBILITY | Much like a traditional bank, Diamond Banc also enables our clients to borrow funds and access a continual line of credit. Our flexible repayment terms mean that as long as your loan pawn is in good standing, Diamond Banc allows customers to draw funds up and down against their items, like a credit line, or credit card. We have several local Miami small business owners that have received a pawn loan in the past and now know the funding they can access using their jewelry, watches, or diamonds.
  • HASSLE-FREE REPAYMENT | In the decade following Diamond Banc’s inception, we quickly realized that every situation is different. Some of our clients need immediate funding for a personal financial situation while some of our clients want to borrow funds for a business opportunity. Consequently, Diamond Banc in Miami strives to be flexible to meet all of our customers’ needs. We can work with you to create an easy repayment plan for you and your financial needs. Diamond Banc also allows you to pick your monthly payment date. Compared to a traditional pawn, Diamond Banc allows you to make principal payments above the monthly interest payments, which will lower your total principal amount and monthly interest loan pawn payments, resulting in a faster repayment process.
  • BEST LOAN TERMS | Diamond Banc in Miami will offer you the best local option of a high pawn loan amount and low borrowing costs of funds. In fact, we are so confident in our loans that we encourage our customers to shop around Florida to make sure they feel equally as confident in our offers. Our offers never expire, meaning that you have a chance to compare our offers with other pawn shops. Check with the others who offer pawn jewelry loans first, then come see the vast difference doing business with Diamond Banc Miami will make.
  • CONTACTLESS, DIGITAL, & AUTOMATIC REPAYMENT OPTIONS | Never worry about forgetting your loan pawn payment! Diamond Banc offers an automatic payment option, which makes it easy to pay your loan back quickly. We set up your account to automatically ensure your monthly payment is made, without adding another thing for you to remember. We know our clients are busy and we aim to make the pawn loan process an easy, seamless experience.
  • BUSINESS & PERSONAL USE LOANS | Loans from $500 to $275,000 are available for business or personal use. Our vast flexibility means we can offer a myriad of values to our customers.
