Two cavities measuring to 1.5cm x 1.3cm in a Quartz matrix are heavily lined with sparkling druses of deep blue crystals of the rare mineral Clinoclase. Light green classic habit crystals of Liroconite measuring to 1mm are largely to be seen on the reverse of the specimen. There are also several cavities also lined or scattered with well formed micro-crystals of Clinoclase. A typical milky Quartz matrix is veined with light green Chrysocolla. A fine specimen from this celebrated Cornish mine.
