Index prices are calculated from an equation which begins with the cost of rough material, cost of lapidary, cost of distribution, supply and demand, economic conditions, and the strength of the U.S. dollar. Prices are independent sources of information taken from a systematic record of transactions from mining to distributor. Each information box and category presents price guidelines which are individually established, setting us apart from other pricing structures and allowing the reader to keep track of pricing trends by following each box on a monthly basis.
