An excellent rounded floater of fully crystallized stannite intergrown with elongated zinkenite crystals. Stannite is a complex aggregate of parallel crystals, complete all around, with minimal contacts and excellent metallic lustre. Zinkenite features elongated crystals, often piercing stannite, of very good for the specie lustre. Both species are very fresh and display very well.
In great conditions. Very rare to spot a stannite of such a quality!
