Cerussite

XL cerrusite crystal with great luster and incredible reaction under UV light.  If you are a fluorescent collector this one is a great find!  The crystal feels heavy in the hand and smooth to the touch, and presents a soft off-white color under normal light.  It is quite large and one of the best and biggest we saw available in Tucson that year.
 
From Lidal Mine, Morocco.  Acquired in Tucson, 2024.  Shown mounted on putty on our medium acrylic base, included with purchase.  
 
Cerussite is a lead carbonate mineral prized by mineral collectors for its stunning crystal forms and incredible fluorescence. It often forms clear, white, or gray crystals, though impurities can lead to variations in color, including shades of green, blue, or yellow. Cerussite is typically found in a variety of crystal habits, including acicular, tabular, and prismatic forms, often twinned or forming complex reticulated (lattice-like) structures. With a high refractive index, cerussite crystals exhibit an adamantine luster, making them exceptionally brilliant and eye-catching.
 
This mineral is relatively soft, with a Mohs hardness of 3 to 3.5, and heavy, due to its lead content. Cerussite often occurs as a secondary mineral in the oxidation zones of lead ore deposits, frequently associated with other lead minerals such as galena and anglesite. Collectors value cerussite not only for its beauty and diversity of forms but also for its relative rarity and the fascinating environments in which it forms.
