Product information

A pale blue Fischer Stone cabochon with dendritic plumes from China.

Strictly speaking, Fischer Stone is a natural Agate which has been altered. It is named after Dr. George W. Fischer, who discovered a technique for creating dendrites in Agate using a process of electrochemical displacement. 

The stone is soaked in Muriatic acid and a copper dye for 2 weeks, following which a rod of either iron or aluminium is placed onto the Agate where the dendrite forms over several weeks. Due to the complex and time-consuming process these gems were not produced in large numbers.
