The light blue green phosphophyllite crystals reach 4-6 mm and are crystallized throughout the matrix in vugs. The crystals are very perfect with typical "fish-tail" (twinned) habit, in the front there's a 1.4 cm aggregate. Also present is some parascholzite and fairfieldite associated. The matrix is a combination of quartz and feldspar matrix, also present in it is what appears to be massive dark blue vivianite.
