This is an excellent specimen of Leadhillite because the crystals are discrete and isolated, plus it has good color. The crystals are a beautiful robin's-egg blue with a very good resinous luster. The numerous crystals also have a noted classic morphology for the mineral: curved hexagonal prisms. Overall, this is a terrific specimen in terms of significance and showiness for a leadhillite for this mine. 2.4 x 2.2 x 1.8 cm
