AI-assisted summary
Description from the seller
From our selection of collectible minerals, we propose a remarkable aggregate of Calcite crystals from the San Giovanni Mine, Bindua, Iglesias, in Sardinia.
Moreover, it is characterized by a botryoidal structure with grouped crystals forming globules and radial tufts, with a pronounced color contrast between pure white and ochre-yellow shades, as well as the specimen’s generous dimensions—features that increase its aesthetic value and mineralogical importance. The sample stands out for the quality of crystallization and for the overall aesthetic balance, with characteristics that enhance its natural structure and visual impact.
Calcite is the most widespread calcium carbonate (CaCO3) in nature and can take countless crystalline forms; yellowish hues like those of this specimen often derive from iron oxide inclusions or impurities present in the hydrothermal fluids during formation. The San Giovanni Mine, in the Iglesias belt, has long been one of Sardinia’s most important lead and zinc mining centers, and its cavities have yielded numerous Calcite specimens of museum quality as a secondary product of mineralization.
This is an ideal specimen for mineral collections, display, and for those who appreciate the natural beauty of minerals, also in the context of crystal therapy and lithotherapy, in line with the properties traditionally associated with the mineral species.
All the minerals are 100% natural and untreated, with rare exceptions always noted in the description. Photographs are taken with professional lighting to best showcase colors and details; however, slight color variations may occur depending on the device or ambient light.
Shipping is carried out via reliable and selected express couriers, with fast delivery (in many cases 1-2 working days within Europe), tracked and insured shipping and professional and safe packing, as confirmed by customer reviews. Deliveries can also take place 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 deadlines, simply by contacting us to organize the consolidation. For important pieces, direct home delivery by appointment or at major European fairs is also available.
