Tridymite and Siderite from Vechec quarry, Slovakia

Tridymite and Siderite from Vechec quarry, Vechec, Vranov nad Topľou District, Prešov Region, Slovakia

Nice little specimen of an uncommon mineral - Tridymite and Siderite from Vechec quarry, Slovakia.

Tridymite is a polymorph of Quartz - meaning it is also SiO2, just 'formed differently' to Quartz. This is a micro mineral and I highly recommend magnification for viewing it. 

Comes boxed with our ID label and a former retailers label - great for collectors of minerals from Slovakia, or the interesting polymorphs of Quartz.
