Abstract: An information processing system for electronically vertically integrating a consumer, retailer and wholesaler of diamonds (or jewelry) includes maintaining a diamond inventory database which lists common characteristics, wholesale price and retail price. In the retail facility or space, the consumer electronically searches the diamond database and is presented with record displays of diamonds within the scope of the search and the retail price. A retailer's computer can mimic the consumer search and display the wholesale price. This tracking and a sales alarm trigger facilitates a face-to-face sale of the diamond. An alarm issues when the consumer's search exceeds certain predetermined parameters.
