Larger specimen with coating of cuprian Austinite. This specimen may require anaylsis as distinguishing Conichalce from Austinite is difficult visually on this scale. Although, near the outer edges of the specimen the morphology of the light green, glassy crystals to 1mm are cuprian Austinite. These crystals are slender and prismatic with sharp, pointed terminations. This area phases into the sugary, darker green area and may phase into Conichalcite.
