Due to its similarity in appearance to sapphires, Tanzanite is getting plenty of attention from jewellers as a "rising star" among colored gems. Benjamin Hackman, president of the International Colored Gemstone Association, offers some tips for buyers interested in this natural stone about its value, features and availability.
