A giant fluorescent sculpture – Aragostronzianite and Chalk, Boccheggiano, Tuscany

With an imposing weight of 1817 grams and exceptional dimensions of 200 x 135 x 71 mm, this specimen represents one of the most spectacular and rare combinations in Italian mineralogy: aragostronzianite and gypsum associated on a geode matrix from the historic deposits of Boccheggiano, near Montieri, in the province of Grosseto.

We are faced with a true mineralogical giant, now almost impossible to find today. Discoveries at this location have drastically decreased, making each surviving specimen a precious testament to a past geological era. This particular sample is a genuine museum piece: massive, spectacular, perfect for any collection that wishes to showcase a prominent and absolutely unique element.

The surface of the block is studded with open geodes, revealing inside aggregates of aragostronzianite, a mineral known for its extraordinary pink fluorescence under UV light, capable of emitting ethereal and captivating reflections. In some geodes, there are also gypsum crystals, which emit a deep, bright blue under short-wave ultraviolet light, creating a chromatic contrast between pink, violet, and sky blue that captures and holds the viewer's gaze.

Every angle of the piece reveals new details: sparkling microcrystals, iridescent surfaces, perfectly preserved cavities. Such a specimen is not only an aesthetic rarity but also a window into a complex geological system formed under very specific environmental conditions that are no longer active today.

Kire Minerals is proud to present this extraordinary specimen of aragostronzianite and gypsum: a giant of fluorescence, an unrepeatable fragment of Tuscan mining, combining rarity, exceptional size, and breathtaking natural beauty.
