Important mineral collection – 25 selected samples, 5.6 kg between great Italian classics and international rarities This important mineral collection brings together 25 selected samples, for a total weight of 5.6 kg, equal to 5,600 grams. The collection includes a significant variety of Italian and foreign minerals, with specimens from some of the most important localities in Italian mineralogy, alongside interesting international samples from South Africa, Namibia, Madagascar, Russia, Switzerland, Australia, Portugal, Spain, India and Peru. Among the most significant pieces stand out a splendid association of datolite and large, strongly fluorescent calcite crystals from Sasso di Castro, a beautiful green fluorite from Mandrosonoro, a rare Peruvian tetrahedrite, and numerous samples from historic Italian localities. A collection that blends aesthetics, mineral variety, fluorescence phenomena, pseudomorphism and important provenance. The lot includes: • Fluorescent datolite and calcite – Sasso di Castro, Firenzuola, Tuscany One of the most important pieces of the entire selection. A splendid association of datolite and large calcite crystals, characterized by particularly intense fluorescence under ultraviolet light. A sample of notable aesthetic impact. • Hematite and quartz – Cantiere di Valle Giove, Rio Marina, Elba Island, Tuscany Classic Elba mineralogical association, from one of the island’s best-known mining sites. Interesting for the contrast between metallic hematite and quartz. • Beta quartz – Castelluccio di Moscheda, Modena, Emilia-Romagna Appennine specimen with the characteristic skeletal crystal habit commonly defined as beta. A Modenese mineralogy classic, linked to the ophiolitic contexts of the Apennines. • Pyrite – San Clemente, Monterenzio, Bologna, Emilia-Romagna Specimen from a historic Bologna locality, appreciated for pyrite crystallizations and strong collecting interest. • Calcite and barite on septarian nodule – Gaiano, Collecchio, Parma, Emilia-Romagna Interesting association of calcite and barite developed inside a septarian. A representative sample of the sedimentary mineralizations of the Parma area. • Mammillated hematite – South Africa Hematite specimen characterized by the typical mammillated morphology, with rounded and botryoidal surfaces. A growth form highly appreciated for its particular aesthetic appearance. • Quartz – Ponte della Venturina, Bologna, Emilia-Romagna Specimen from a Apennine locality known for its quartz, especially valued in Italian collecting. • Gypsum – Gabicce Mare, Pesaro and Urbino, Marche Classic gypsum specimen from the Adriatic area, interesting for crystallization and connection with evaporitic formations of the Apennines. • Fluorite – Namibia Fluorite specimen from Namibia, a country known for its numerous mineral localities. An interesting international presence to complete the collection’s variety. • Quartz hopper-style – Porretta Terme, Bologna, Emilia-Romagna Specimen characterized by a particular skeletal crystal growth, commonly defined as hopper. Interesting for morphology and Apennine provenance. • Fluorite and hematite – Rio Marina, Elba Island, Tuscany Interesting association of fluorite and hematite from the famous Elba iron district. A specimen of notable interest for the mineralogical combination and locality. • Sulfur – Le Cetine di Cotorniano, Chiusdino, Siena, Tuscany Classic native sulfur specimen from the historic Tuscan locality of Cetine, known for antimony-bearing mineralizations. • Gypsum – Secchiano, Emilia-Romagna Specimen from an Apennine locality known for gypsum mineralizations. Interesting for provenance and collecting value. • Quartz with goethite pseudomorph on pyrite – Bruzolo, Turin, Piedmont Interesting association where iron oxide products preserve the original pyrite crystal morphology. A representative example of pseudomorphism. • Green fluorite – Mandrosonoro, Madagascar One of the most interesting pieces in the entire collection. Stunning green fluorite from Mandrosonoro, known for its cube crystallizations and intense green tones, sometimes with bluish optical effects. A provenance highly appreciated by international collectors. • Rhodochrosite – Russia Rhodochrosite specimen, manganese carbonate known for its pink to reddish hues. A species particularly appreciated for color and mineralogical interest. • Ciniane – Ticino, Switzerland Alpine ciniane specimen, aluminum silicate typical of metamorphic environments. Interesting for Swiss provenance and systematic value. • Arsenic – Australia Australian specimen labeled as arsenic, interesting for the presence of this relatively uncommon species in mineral collections. Requires careful preservation, avoiding abrasion, breakage, and dispersion of powders. • Staurolite – Portugal Staurolite specimen from Portugal, silicate typical of metamorphic rocks. A mineral particularly interesting for its crystallographic characteristics and systematic value. • Quartz – Selvino, Bergamo, Lombardy Quartz specimen from a Lombardy locality known in Italian mineral collecting. Interesting for provenance and crystallization. • Pyrite – Livorno, Tuscany Pyrite specimen from the Livorno area. A representative example of one of the most well-known and valued metallic sulfides in the mineral world. • Calcite – Tuscany Tuscan calcite specimen, interesting for crystallization and provenance. A classic presence that enriches the carbonate diversity within the selection. • Fluorite – Berbes, Asturias, Spain Classic specimen from one of Europe’s most famous fluorite localities. Berbes is particularly valued for crystal quality and the collecting value of its specimens. • Stilbite – Pune District, Maharashtra, India Indian stilbite specimen, a zeolite mineral. The Pune district is internationally known for its important mineralizations in basalt rock cavities. • Tetrahedrite – Lima, Peru One of the collection’s mineral rarities. Tetrahedrite specimen from Peru, belonging to the sulfarsenide group. A species of notable systematic interest, particularly appreciated by specialists in metalliferous mineralizations. ⸻ This important mineral collection comprises 25 samples for a total weight of 5,600 grams, from numerous Italian and foreign localities. The selection stands out for the variety of species and for the presence of particularly interesting specimens, including the datolite with large, strongly fluorescent calcite crystals, Mandrosonoro green fluorite, Peruvian tetrahedrite, and the Elba Island mineral associations. An ensemble that allows appreciation of different mineralogical phenomena, from pseudomorphs to hopper crystallizations, up to fluorescence under ultraviolet light. The presence of numerous samples from classic Apennine and Alpine localities and from major Italian mining districts makes this collection particularly interesting for Italian mineral enthusiasts, without compromising the charm of major international localities. Kire Minerals is proud to offer this important mineral selection, personally curated by Erik Lombini with the usual passion and expertise. Each specimen has been evaluated for aesthetic, scientific, or collecting interest, with the aim of offering an authentic, varied collection representative of the extraordinary diversity of the mineral world.
