Our vast network of over 20,000+ buyers & collectors ensures that we can make industry-leading offers for your items.

What if I don’t accept the final purchase offer?

If you elect not to accept our purchase offer, we will expedite your jewelry back to you under a fully-insured shipping label.

What types of jewelry do you accept?

Diamond Banc actively purchases diamonds 0.50ct+, engagement rings, diamond jewelry, estate jewelry, & signed designer jewelry from designers such as Cartier, Tiffany & Co., Harry Winston, Van Cleef & Arpels, Graff, and more.
