Frequently Asked Questions

  • What does Worthy do?
    Worthy is an online auction house where private individuals can sell their diamonds and luxury watches to professional, trustworthy buyers.

  • What is The Worthy Jeweler Network?
    The Worthy Jeweler Network is the place for jewelers to quickly sell their pre-owned inventory & buy authenticated diamond jewelry for wholesale value.
  • How does selling on the platform work?
    1. 1. Briefly describe the item and Worthy’s pricing engine immediately provides an initial indication of the wholesale value.

    2. 2. We then pick up the item and deliver it fully insured to NY for grading by GIA (or IGI) and for photographing with state of the art 3D cameras.

    3. 3. We offer an Advance Payment that is based on the grading. Once you accept the advance offer, the payment is immediately transferred and is considered the reserve price. In the case you choose to set a higher reserve price, you will not be eligible for the advance payment offer.

    4. 4. After setting the reserve price for the item as well as the duration of the online auction (1-30 days), Hundreds of jewelers and traders are invited to bid. You can watch the live auction and invite additional buyers to bid.

    5. 5. When the auction ends and the highest bid is above the reserve price, we transfer the bid amount and any amount that is in excess of the Advance Payment (if accepted) to you. If the auction ends below the reserve price, you have the option to reject the deal and have the item returned to you.
  • What is an Advance Payment?
    It is an amount offered to you prior to the auction, based on the grading results. If accepted, the amount is transferred to you immediately, and determines the reserve price of your auction. If the leading bid of the auction is higher than the reserve price, you receive the excess amount. Accepting the Advance Payment guarantees the sale of your item at that price.
  • What is a reserve price?
    The reserve price is the lowest price that you are committed to accepting for your valuable. If the leading bid at the end of the auction meets or exceeds this price, the sale will be approved automatically. If the leading bid does not reach the reserve price and you did not select the advance payment option, you may reject the offer and have your valuable shipped back to you fully insured, free of charge.
  • How do I send my valuables to you?
    Immediately following the initial market value calculation, you are provided with a fully insured, pre-paid shipping label addressed to our headquarters. You can either drop off the package at a FedEx location, or arrange for a free FedEx courier pickup.
