2 lbs Brochantite, Conichalcite, Rosasite 5-Piece Set - Ojuela Mine L161
This lot is a fantastic representation of the complex paragenesis in the oxidation zone of the Ojuela Mine. The set features a rich association of three secondary minerals: Brochantite, Conichalcite, and Rosasite. The greatest visual attraction is found in the vug (cavity) of the main piece, lined with delicate emerald green acicular (needle-like) crystals of Brochantite. These crystals contrast beautifully with the green microcrystalline crusts of Conichalcite and the subtle bluish-green tones of Rosasite spreading across the dense ferruginous matrix (gossan).
As the photographs reveal, this 5-piece lot (total weight 2 lbs / 907 grams) offers an amazing level of detail and chromatic contrast. It is an ideal set for collectors looking to study the crystallization and coexistence of sulfates, arsenates, and carbonates in the same geological environment.
