Very interesting specimens where kyanite replaces chiastolite, a variety of andalusite, in a graphitic matrix. The specimen shows characteristics associated with the pre-existing andalusite, such as twinning, indicated by the two different orientations of the kyanite replacing it. It is accompanied by prismatic honeyed chiastolite crystals.They have been analyzed. For lovers of rare pseudomorphoses. Very fluorescent (orange) under UV-LW light.
