Bismuth is a semi metal element used in all manner of industrial and pharmaceutical products. This bismuth has been found in its non-crystallised, grey-silver form, heated until molten and then cooled to naturally allow the bismuth to form into its characteristic cubic crystals.
The iridescent rainbow colour is a result of oxidisation as the stair-step crystals cool.
These mind blowing crystals are made in the UK.
