Aurichalcite from 79 Mine, Arizona, USA

When encountering an attractive blue mineral, it’s often a good guess that it might be one of the many secondary copper minerals. Aurichalcite, (Zn,Cu²⁺)₅(CO₃)₂(OH)₆, is a striking example of a highly colored, copper-bearing mineral. It typically forms in the oxidation zones of zinc–copper deposits. Aurichalcite crystals are acicular to fibrous and frequently occur in aggregates. Although generally considered rare, aurichalcite is widespread in occurrence and often found alongside other collector-favorite minerals, including malachite, azurite, cuprite, smithsonite, hemimorphite, hydrozincite, and rosasite. While it can be modestly priced and accessible from numerous localities, its vibrant color and form make it a staple in many mineral collections. Aurichalcite is also a traditional favorite among micromounters due to its delicate and intricate crystal forms.

This was photographed in the early 2020, the first close-up photo I have taken! Since school's final season was insanely busy, good to go through some of my old-time photos lol.
