White Chabazite After Apophyllite on Chalcedony with UV Reactive Calcite – Maharashtra, India – 1.67 lbs

This exceptional White Chabazite After Apophyllite on Chalcedony from Maharashtra, India weighs 1.67 lbs and measures approximately 4 in x 2 in x 7 in, showcasing a remarkable mineral replacement specimen enhanced by naturally occurring UV-reactive calcite.

The specimen features bright white chabazite crystals that have replaced earlier apophyllite crystals, preserving the original crystal habit through a fascinating geological process known as pseudomorphism. These intricate crystal formations rise from a contrasting chalcedony matrix, creating a striking display of texture, color, and mineralogical complexity.

Adding to its appeal, the specimen contains UV-reactive calcite that fluoresces under 365nm ultraviolet light, revealing hidden mineral features not visible under normal lighting. This dual-display characteristic makes the specimen equally attractive in both daylight and UV mineral collections.

Its tall vertical form and abundant crystal coverage create outstanding display presence, while the preserved crystal structures provide a visual record of the mineral replacement process that occurred during formation.

Mineralogical Notes:

Chabazite is a zeolite mineral commonly found within volcanic cavities. In rare cases, it replaces pre-existing apophyllite while preserving the original crystal shape, creating a pseudomorph. The associated chalcedony formed from silica-rich fluids, while calcite deposited during later mineralization stages and exhibits fluorescence under longwave ultraviolet light.

Collector Notes:

Pseudomorph specimens are highly collectible due to the geological story they preserve. Examples featuring chabazite after apophyllite, attractive chalcedony matrix, and UV-reactive calcite are considerably less common and appeal to collectors of zeolites, fluorescent minerals, and unusual mineral associations.
