Our system was designed to ensure the security of your items. We use bar coded tamper evident bags to secure your items. These bags CANNOT be opened after they have been closed.

How It Works

1. Call us at one of our many locations or call us toll free at 1-800-317-5510 to request a shipping envelope and bar coded tamper evident bag.

2. Once you have recieved the tamper evident bag, place your unwanted Jewelry, necklaces, or other jewelry into the bag. CONFIRM everything is in the bag!

3. Document your jewelry items on the bag, and fill out the information on the front of the bag.

4. Insert the tamper evident bag in the pre-addressed & INSURED shipping envelope.
5. Once the bag is recieved we will confirm the tracking numbers. After the items have been documented we will photograph the items. We will then send YOU a picture of your items SEALED in the condition that you sent them.
6. After you have CONFIRMED that these are your items IN the condition you sent, will we quote you a rough estimate. BEFORE THE BAG IS EVEN OPENED!
7. IF YOU AGREE TO THE PRICE, then we will open the bag.
8. Your items will then be tested for value.
9. After determining the value, we will contact you with the final price and issue you a check.
10. CASH THE CHECK!
