Flower Calcite – Mina Buena Tierra, Francisco Portillo, West Camp, Santa Eulalia district, Mun. de Aquiles, Serdan, Chihuahua, Mexico
 Absolutely aesthetic collection piece of a "Mariposa" habitus calcite, also called flower calcite.
 The Mariposa habit is formed by two generations of calcite. The first consists of scalenohedral crystals with a dark iron oxide coating. High-luster, transparent calcites with hematite inclusions form a flower-like border. The interplay of colors and shapes creates this wonderful variety and makes calcites from Mia Buena Tierra extremely sought after among mineral enthusiasts.
