MRX37CD5: Aggregate of fine tabular Azurite crystals forming rosettes of very vivid and uniform color, on small remnants of blackish rock matrix. The morphology of the crystals stands out, forming a lattice of concentric growth from the matrix, an unusual habit for Azurite specimens from Chessy-les-Mines, the type locality for this mineral species. A very fine specimen.
