Brazil's tourmaline, especially Pale's tourmaline, is valuable because of its unique color and scarcity. Known as the King of Tourmaline, the price of Pale Babi Tourmaline has been rising in the past few years. Since 1989 "Paraiba" made its debut at the Toussaint Jewelry Fair, its price has soared nearly 10 times in a week, reaching $2,000 per carat. The auction price has repeatedly refreshed people's cognition, which shows its huge investment value.
