All of our minerals are 100% Genuine Specimens & come with a Certificate of Authenticity.

Specimen: Bismuth

Location Formed: UK

Scale cube=1cm: Full sizing please see photo

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. Once cooled to a solidified state & exposed to the atmosphere, the crystal form reacts with the oxygen to produce these beautiful colours.

**Warning: DO NOT Hammer or break this rock up without wearing a mask and gloves, as inhalation of the fine particles may cause ill effects, and shards from this mineral can be very sharp.
