The Bourse runs weekly trading days. These trading events are attended by many diamond dealers, who use the opportunity to network, converse, and (obviously) trade goods. In addition to the regular trading activity at the Bourse, the Bourse also hosts special sale events. In such events a certain company or member, bring in a large quantity of goods and offer them for sale, either using the tender method, or by conducting direct sales. These special events tend to draw a large number of members and guests, which in turn, helps to establish new contacts, offering the attendants new opportunities for dealer-to-dealer and dealer-to-retailer exchanges.
