Large Prehnite specimen with an unusual form. It's solid crystallized Prehnite composed of a mixture of yellow Prehnite with distinct crystals
and areas of blue/green Prehnite with a more botryoidal form. This blue/green Prehnite is new to me and I've only seen it in recent lots. Has attached Graphite in areas.
