Several tiny Joaquinite crystals rest on the decayed serpentine base of this hand specimen. These crystals do not exceed 0.1 (3 mm) and are in excellent condition, showing no appreciable damage. Their monoclinic prismatic form is difficult to study without magnification, but appears to be quite good. All have a mahogany-brown coloration and a greasy-to-pearly luster. They are accompanied by a few broken neptunite crystals and a small patch of massive natrolite.
