ABOUT DIAMOND BANC
Diamond Banc's Industry & Dealer Division supplies the jewelry trade with pre-owned luxury watches, certified diamonds, and estate jewelry. Vault is the fastest way for dealers to see what's new and act on it first.
A Diamond Banc dealer account is required to buy. No payment is collected in the app at the time of bidding or offering — winning bids and accepted offers are invoiced through standard checkout for physical goods shipped to the dealer.
