Solid, translucent yellow Prehnite with large, chunky crystals. This is a very good one with a little contacting on the left edge and a partial Tanzanite attached near the base, but the entire front display face is perfect undamaged large crystals.

Translucent blue/green Prehnite crystals with both a color and form new with these late 2018 finds of Prehnite from Merelani. These recent Prehnite have rounded orb formations that morph out into flat bladed crystals. The color, a blue/green/yellow is also a little different than I've seen before in Merelani Prehnites. Undamaged.
