Several years ago in the mid-90s when these were first found, they were plentiful. I don't see many now. This specimen is comprised of two pastel green, translucent, matte luster, radial aggregates of prehnite. The piece is flat and contacted on back, but technically complete all aroound. It is very translucent with good lighting. The largest aggregate of radial crystals measures 5.0 cm across which makes this a substantial prehnite crystal for ANY locality!And it is gorgeous, too...
