Let’s Have a Deal
Here’s why Boston area customers choose Deal Zone when selling gold, jewelry, and other precious metal items:
We accept natural (earth-mined) diamonds starting from 0.25 carats. If your diamond has a GIA certificate, we can provide an immediate appraisal. If no certificate is available, we will most-likely need to evaluate the diamond in-person to offer a quote.
Our offers are based on the current market value of diamonds and the specific characteristics of your stone, such as the Four C’s (Carat, Color, Clarity, and Cut). For branded diamonds from renowned designers like Cartier, Tiffany, or Van Cleef, we offer a separate appraisal process, taking the brand aspect into account.
Payment is immediate. Once we agree on a price and verify your items, you’ll receive cash on the spot. It takes 10-30 minutes to evaluate most diamonds. Certain stones (especially if mounted) might require a bit more time to evaluate. If you send your diamonds by mail, payment is typically issued within 24 hours of receiving and verifying the items.
No, we operate transparently. There are no hidden fees or commissions. For items sent by mail, we also offer free prepaid shipping.
Walk-ins are welcome during business hours. If you would prefer to visit outside regular hours, appointments may be available by call, text, or WhatsApp.
Please bring your diamond item and a valid government-issued photo ID. If you have a GIA report, original paperwork, receipts, or any supporting documentation, bring those as well, as they may help speed up the evaluation process.
No, a GIA certificate is not always required. However, if your diamond has a GIA grading report, it can help us provide a faster and more accurate initial quote. If there is no certificate, we may need to inspect the diamond in person before making an offer.
Many diamond evaluations can be completed in about 10 to 30 minutes, depending on the item. Loose certified diamonds are often faster to review, while mounted stones or more complex pieces may take longer.
