Bismuth: Bismuth has been known since ancient times. It was often confused with tin and lead, however, it is an element in its own right, number 83 on the Periodic table. In its naturally occurring form, it is an iridescent silvery white crystalline, brittle metal and is very rare. It is more usually a rainbow coloured crystal obtained as a by product of mining and refining lead, copper, tin, silver and gold. Traditionally, Rainbow Bismuth is believed to have been used to help ease through transitions, encouraging a calm acceptance of change and increasing our energy levels to be able to adapt and transform.
