Bismuth chemically resembles arsenic and antimony. Elemental bismuth may occur naturally, although its sulfide and oxide form important commercial ores. Bismuth is the most naturally diamagnetic element, and has one of the lowest values of thermal conductivity among metals.
These specimens have been man produced. This process is completed by melting the raw natural mineral at a very high temperature and allowing it to crystallise or ‘grow’. Once cooled to a solidified state & exposed to the atmosphere, the crystal form reacts with the oxygen to produce these beautiful colours.
Man Produced in UKACTUAL AS SEEN: The image shows the EXACT specimen you will receive. The specimen has been carefully hand selected and photographed. Measurements are as accurate as possible, though be aware measuring precise dimensions can be difficult from irregular shaped items. Whilst we portray colours as close to life-like as we can, colours will vary if taken in sunlight, indoors, from monitor to monitor and device to device. Once this specimen is sold, we will update this listing with new similar selected item, with a new photo and dimensions.
