This specimen was self-collected in 1979 by Arnold Hampson. The extraction from the basalt matrix was expert as there are no scratches or dings anywhere. The Stilbite is a soft faint pink color. The crystals are perfect sheaf-like in habit and display a pearly luster. The largest crystal group is 3.5cm!
