Stalactitic chalcedony geode "The Abalone" Stalactitic chalcedony ** Brittle warningLocale: Atlas Mountains, Morocco Approx dimensions: 5 x 4 x 2" Approx weight: 393g These unusual geodes from Morocco are like small caves lined with stalactites, botryoidal forms, and swirling agate patterns. While commonly called red chalcedony, I find the color is more orange to red orangeor in the case of this specimen, more brick red orange. Hematite causes this coloration, but later phases of growth (second generation) dont contain hematite
