About this specimen
This exceptional Arsenopyrite Cluster with Quartz and Calcite is a stunning natural specimen sourced from Peru. The cluster features multiple well-formed crystals displaying metallic luster that makes it a standout addition to any mineral collection.
Calcite (CaCO₃) crystallizes in the trigonal crystal system with a Mohs hardness of 3. This mineral is known for strong double refraction (birefringence), rhombohedral cleavage, and reactivity with dilute hydrochloric acid. Specimens from Peru are particularly valued among collectors for their quality and character.
This specimen weighs 1.94 oz (55.0 g) and measures approximately 1.7 × 1.4 × 1.2 inches, representing a rare example. Each specimen is carefully hand-selected to ensure excellent crystal development, natural aesthetics, and display-worthy presentation. Photographs represent the actual specimen you will receive.
Whether you are a seasoned mineral collector, a geology enthusiast, or searching for a distinctive natural display piece, this Calcite specimen offers exceptional quality and visual appeal. It makes an impressive addition to a specimen cabinet, educational display, or curated mineral collection — Calcite is one of the most common minerals on Earth, valued by collectors for its incredible crystal diversity and optical properties.
