M683 - Andalusite crystals with graphite inclusions, which is then called Chiastolite. "Chiasma" is Greek for "cross."

These nice specimens of Chiastolite are from China.

Some of the specimens we received did not have the graphite inclusions which produce the "chiastolite cross" so we threw those away. All the specimens we are selling have the cross.

These crystals measure approximately 2" to 3" in length.
