Amazing and rare combination of yellow Prehnite with green Tsavorite. The Prehnite occurs as light yellow, bunched clusters of crystals with some attached Graphite on the bottom and small attached Pyrite crystals and Titanite. The Tsavorite are elongated faden crystals to 2.5cm long. Well crystallized on all sides. I've never seen one like it! A must for a Merelani collection.
