Matte brown calcite "moonscape" with 'craters' and large crystals Petrified wood and some pieces have hollowLocale: Santa Eulalia, Chihuahua, Mexico Approx dimensions: 4 x 2. 25 x 1" Approx weight: 130g This material from Santa Eulalia has rhombohedral calcite crystals on a red brown iron oxide matrix. The 'craters' pockmarking the surface create an unusual moonscape appearanceor maybe more Mars scape with the flat red color of the piece. The crater shapes appear to be the remnants of a crust that had formed over crystals that have since dissolved away.
