Item Description

Wonderful, gemmy, lustrous, fine blue colored crystals of Indicolite Tourmaline from the famous Pederneira Mine. The larger crystal shows a bit of a pink hue at the core, while the smaller crystal is very consistent with its blue color throughout. No damage, and a showy thumbnail specimen of this classic material. From the collection of Rolando Gioia (a contributor to new definitive book on Brazilian minerals: "Minerais e Pedras Preciosas do Brasil").
