A fine combination specimen from the gneiss quarries at Arvigo, Switzerland. An attractive cluster of lustrous and translucent, helmet-shaped, pastel-green prehnite crystals is well-placed on a matrix plate covered with snow-white orthoclase variety adularia. The plate is richly sprinkled with gemmy, acicular, olive-green epidote crystals. Collecting is now forbidden at the quarries. Ex. Rolf Wein Collection, acquired in 1967.
