A very rich and showy miniature covered with lustrous, turquoise-blue and green liroconite crystals and aesthetically set in quartz-rich matrix from the famous Wheal Gorland Mine (Type Locality) of Cornwall. The richness of green liroconite is unusual. Liroconite is a Holy Grail species for Cornwall or English collectors, among the rarest ever found in beautiful crystals, and this is a good one that is a display specimen AS WELL AS a reference piece. Mined in the 1820s-1850s.
