2.4" Huge, Cerussite Crystal on Galena & Bladed Barite - Morocco

This specimen contains translucent cerussite crystals that formed from orange bladed barite and galena that was collected from Mibladen, Morocco.

Under UV lighting, the cerussite crystals fluoresce a vibrant yellow color.

Cerussite is a carbonate mineral with the chemical formula PbCO3, and is an important ore of lead. This lead-carbonate consisting mineral is a common weathering product of galena, explaining why it is typically extracted from oxidized zones of lead ore deposits. It can form into a variety of different structures, sometimes in fibrous patterns, other times in granular aggregations, though generally forming vitreous pseudo-hexagonal crystals. The colors of this mineral vary depending on composition and structure, with colorless, white, grey and green tinted, being the most common colors of crystals found.

Barite, commonly spelled baryte, is well-known for its great range of colors and varied crystal forms and habits. It is a heavy mineral consisting of barium sulfate, and typically has the chemical formula of BaSO4. The barite group consists of baryte, celestine, anglesite and anhydrite. It's generally white to colorless and is the main source of barium.
