Tourmaline on Quartz (ex Rolando Gioia Collection)

Item Description

A sharp, lustrous, thin, prismatic Schorl Tourmaline crystal is aesthetically set atop a very gemmy, colorless, highly compressed Quartz crystal creating a very showy and worthwhile thumbnail specimen. The crystal appears black at first glance, but with strong backlighting, you can see there is a range of deep green hues inside. Good quality all around, better in person! From the collection of Rolando Gioia (a contributor to new definitive book on Brazilian minerals: "Minerais e Pedras Preciosas do Brasil").
