(Mining.com) - The mechanism to buy and sell rough diamonds is bizarre. Diamonds are sold in “boxes”, collections of diamonds with similar characteristics, where values ranging from $100,000 to $1.5 million. Approximately 5,000 boxes are available for sale at 10 occasions per year which are known as “sights”. No negotiation occurs and there is no cross access between boxes assigned to other customers. This strange structure triggers lots of questions. To help us understand these aspects, Game Theory is a useful framework in order to assess the interaction and sheds light into the strategies undertaken by the buyer and the seller.
