Antlerite is a copper sulfate hydroxide mineral that forms in secondary oxide environments. It typically appears as green to blue-green aggregates with a dull to resinous lustre and a tendency to form acicular or plume-like crystals, sometimes resembling antlers in overall habit. The mineral often occurs in oxidized copper deposits where it can crystallize alongside related secondary copper minerals, and in some localities it presents as fibrous or radiating masses that catch the eye of field collectors.

About Antlerite
Notable specimens come from copper-rich districts in Chile, Mexico, and the United States, where secondary mineral assemblages from supergene zones yield bright, well-formed crystals or dense botryoidal masses. Collectors value Antlerite for its distinctive habit and vivid coloration, which contrast with more common sulfate minerals, and for the way it records secondary alteration processes in copper ore environments. Though not among the rarest species, well-preserved, vibrant specimens from key localities can be sought after for display and study.
