Aesthetically nestled in a vug of ocherous limonite are rhombohedrons and scalenohedrons of lustrous and translucent calcite (to 1.8 cm in length) that have been totally included by aurichalcite, giving the crystals a spectacular sky blue color. The contrast to the dark matrix is very appealing, and the association was always rare and highly unusual (for this or any other locale). Beautiful!
