Rare and unusual Amphibole Quartz tumble stone. (Aka Angel Phantom Quartz). These stunning crystals come from Brazil and are not easy to come by. Every piece is different with varying inclusions of Hematite, Limonite and Kaolinite. These pieces have been “Vibro” tumbled, this results in a more natural shape, it simply polishes the stone, keeping the stones natural shape. Metaphysically, it is suggested that Amphibole quartz brings deep peace, and is reputed for its highly spiritual properties.
