Aesthetic fluorescent calcite

From our selection of collectible minerals, we propose an aesthetic group of Calcite crystals from the Zanacchi quarry, Molassana, Val Bisagno, Genoa, Liguria. Moreover, it is characterized by two main Calcite crystals well-formed and transparent, set on matrix and accompanied by small secondary crystals, with tones ranging from white to beige enriched by brown zonation, and by intense red fluorescence and phosphorescence under UV light, which increase its aesthetic value and mineralogical importance. The specimen stands out for the quality of crystallization and for the overall aesthetic balance, with features that enhance its natural structure and visual impact. Calcite fluorescence is generally linked to traces of manganese or other activating elements that substitute calcium in the crystal lattice, while the observed phosphorescence indicates the crystal’s ability to trap and slowly release the energy absorbed under ultraviolet rays. The quarries of Val Bisagno, inland Genoa, are known among collectors for producing calcites with this dual luminescent response, a relatively uncommon combination to observe on the same specimen. Calcite, calcium carbonate (CaCO3), is one of the most widespread minerals in the Earth’s crust, but varieties with marked fluorescence and phosphorescence remain particularly sought after. This is an ideal specimen for mineral collections, display, and for those who appreciate the natural beauty of minerals, also in the realm of crystal therapy and lithotherapy, according to the properties traditionally associated with the mineral species. All minerals are 100% natural and untreated, with rare exceptions always indicated in the description. The photographs are taken with professional lighting to best showcase colors and details; however, slight variations in shade may occur depending on the device or ambient light. Shipping is carried out via reliable and carefully selected express couriers, with fast delivery (in many cases 1-2 business days in Europe), tracked and insured shipping and professional and safe packaging, as confirmed by customer reviews. Deliveries can also occur the day after payment depending on the destination. It is possible to accumulate multiple purchases and receive them in a single shipment, even from auctions with different end dates, simply by contacting us to arrange the consolidation. For important pieces, direct home delivery by appointment or at major European fairs is also available.
