This specimen of clinoclase clinging to liroconite came out of the historic and famous locality of Wheal Gorland, Cornwall, England, the type locality. The brilliant blues of these rarities is striking. No damage
S16360 – Chalcophyllite
An uncommon secondary mineral and Cornish classic of chalcophyllite to 0.5 cm peering out of limonitic matrix. The delicate and beautiful platy rosettes of robin’s-egg blue is by far this specimens best feature. Ex. Bill McBride collection
S12943 – Chalcophyllite
Chalcophyllite is a rare secondary copper arsenate mineral occurring in the oxidized zones of some arsenic-bearing
copper deposits, and it is a classic Cornish mineral once called tamarite. This unique shade of blue green is nearly artificial in person and approaches a full centimeter which is quite large for the soft platy mineral.
S12944 – Chalcophyllite
Cornish classic of electrifying blue green so intense it appears nearly artificial in person. This rare secondary
copper arsenate mineral occurs in oxidized zones of some arsenic-bearing copper deposits and represents the unique species very well.
