Comment: Rare blue tourmaline, at times not perfect with a grayish undertone; and, though deep enough, a symmetric window. At times terrific in a light Windex blue. All-in-all not for the beginner and better in a collection than in jewelry. Part of the new tourmaline parcel from Mozambique but with less Paraiba style. Bargain.
