Spectacular bismuth with countless iridescences! Japan...

Excellent specimen of Bismuth from Japan. Crystalisation achieved in the laboratory by controlled cooling of molten bismuth. Collectors know how much minerals of this type are valued and sought after. The peculiarity of this specimen lies in the crystal formation that develops geometric and concentric structures, with levels that descend toward the center. This shape arises because the crystal edges grow faster than the central part during solidification. The metallic surface, on the other hand, shows violet, blue, gold, green, and pink iridescences. These colors derive from ultra-thin oxide layers that form on the surfaces, creating interference with light. 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, according to the properties traditionally associated with the mineral species. All minerals are 100% natural and untreated, except for rare exceptions always indicated in the description. The photographs are taken with professional lighting to best enhance colors and details; however, slight variations in shade 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 in Europe), tracked and insured shipping and professional and secure packaging, as confirmed by customer reviews. Deliveries can also occur the day after payment depending on the destination.
