Hundreds of small, radiating Mimetite crystals are clustered together on the limonite host rock of this Mexican specimen. The crystals are generally in excellent condition, showing very little damage, and do not exceed 3 mm in length or 2 mm in diameter. On one side of the specimen, they show a color that ranges from pale yellow in the smallest crystals to a dull gold in the larger ones and a pearly luster. The other side of the specimen has crystals that show a dull brown coloration and a dull luster due to the fact that they are covered with a thin layer of limonite. All have warped but moderately good hexagonal prismatic form and tend to be gathered in "sprays", in which the crystals radiate outward from central points. There are a few clusters of heavily intergrown rhombohedral calcites resting among the limonite-coated Mimetites- they have the same brown coloration but show a bright vitreous luster. These calcites cover almost half of the face on which they rest.
