Calcite with red, black, and colorless druzy Smoky quartz but later phases of growth

but later phases of growth (“second generation”) in the geode don’t contain hematite inclusions and are white to colorless

Approx weight: 142g

cryptocrystalline form of quartz

and can make for interesting pieces to cut open

but is stepped down and smaller than the main crystal
