Tourmaline included in Quartz (ex Rolando Gioia Collection)

Item Description

Thin prismatic Tourmaline crystals are included within and penetrating through a colorless, doubly-terminated, GEM quality Quartz crystal from an undisclosed locality in Brazil. The Tourmalines might appear black, but if you backlight them with a strong light, you can see a bit of translucency with greenish, brown and silvery hues. From the collection of Rolando Gioia (a contributor to new definitive book on Brazilian minerals: "Minerais e Pedras Preciosas do Brasil").
