Description

This old (1970s) specimen has been in my collection for decades: a slight greenish well developed Fluorapophyllite crystal on a basalt matrix covered with white stilbite/heulandite forms a very nice and showy display specimen. It was one of my first collection specimens ever and stems from a time when the long prismatic green apophyllites from the Pune district were more abundant ... today, this kind of specimens isn´t found anymore - todays finds have a different shape. My old coll. number is written on the backside with acrylic paint.
