Item Description

Here we have a classic and very hard to find specimen of the well known "Chiastolite" - a variety of Andalusite - from the Ne Plus Ultra Mine in Madera County, California. Like most of the specimens from this locality, this piece has been sliced to show the cross section growth with the dark black carbon inclusions creating a diamond-shaped growth. A lovely toenail sized piece of this attractive material. From the worldwide collection of David Burgess (1951-2016). David was a prolific species collector from Newington, Connecticut, and the namesake for the extremely rare cobalt arsenate species Burgessite, which he discovered.
