11.9 x 7.0 x 5.0 cm. This matrix, stained by multi-colored copper hues, is host to two dark green patches of finely microcrystallized bandylite, a rare copper, boron, hydroxide, chloride. Note also the patches of lighter blue to the right side of the specimen as shown atop: The larger area of bandylite measures over 2.0 cm across. Ex. Philadelphia Academy of Natural Sciences.
MD-178905 - Eriochalcite, Bandylite - - Archived Queténa Mine, Toki Cu deposit, Chuquicamata District, Calama, El Loa Province, Antofagasta Region, Chile small cabinet, 7.8 x 5.2 x 3.0 cm.
7.8 x 5.2 x 3.0 cm. A very rare pseudomorph of bluish-green eriochalcite after crystal aggregates of bandylite on quartz from the bandylite Type Locality, the Quetana Mine of Chile.

TUC8-124 - Bandylite - $ 2000 SOLD Quetena Mine, Calama, El Loa Province, Antofagasta Region, Chile (TYPE LOCALITY) cabinet, 11.9 x 7.0 x 5.0 cm ex. Philadelphia Academy of Natural Sciences
This matrix, stained by multi-colored copper hues, is host to two dark green patches of finely microcrystallized bandylite, a rare copper, boron, hydroxide, chloride. Note also the patches of lighter blue to the right side of the specimen as shown atop: The larger area of bandylite measures over 2.0 cm across. Ex Philadelphia Academy of Natural Sciences, almost certainly from the type find in the 1930s which was named after mineralogist Mark Bandy. Old fashioned wood display label from somebody's display collection , included. This is a MAJOR example of the species with a bit of 3-dimensionality to it, though it is seemingly innocuous in the photos, for the size and richness of the specimen. SIGNIFICANTLY, this specimen does NOT SHOW ALTERATION to eriochalcite, as is common on some specimens and reduces value of even many museum pieces thought to be bandylite (which aren't).
