Here is an attractive golden yellow-green Prehnite made up of translucent crystals, curving in upon each other to make up this beautiful piece. They are so translucent that just a little backlighting shows the shadow of you finger behind it. The color is a lovely, almost glowing yellow-green and they all have great luster! The individual botryoids are composed of relatively distinct, 0.5 to nearly 1 cm crystals arranged in tight, hemispherical aggregates with the individual slightly curving, tapered crystals being somewhat distinct and the faces scintillate, reflecting any incident light! The piece is matrixless which adds to its translucency and only has a trace of bruising locally. A pretty Prehnite from a rare old find in Tanzania, circa 2010!
