Cabinet, 9.5 x 4.4 x 4.0 cm
Antlerite is an uncommon secondary copper sulfate mineral occurring in the oxidized zone of copper deposits in arid regions. Radial clusters of lustrous, olive-green, acicular antlerite crystals are richly scattered on the wedge-like matrix and are seriously complimented by two bands of botryoidal, spring-green chrysocolla. This fine combination specimen hails from a very uncommon for antlerite New Mexico locality - the Tyrone District in Grant County. Older material from the Mullane Collection.
