Colorless calcite with large crystals Hedenbergite UV reactivity: Wulfenite from someLocale: Santa Eulalia, Chihuahua, Mexico Approx dimensions: 3. 5 x 2. 5 x 1" Approx weight: 89g This calcite specimen from Santa Eulalia has large colorless calcite crystals and druzy on a dark iron oxide matrix. The calcite formed a chunky druzy of icy colorless intersecting rhombohedral crystals that almost appear cubic in areas. There are three larger modified rhombohedral crystals perched atop. This is a beautiful example of growth forms typical
