This is a fine thumbnail specimen of natrolite. It is primarily a single large transparent and colorless crystal with a good termination. The surface is covered with lengthwise striations and other crystal growth patterns, hiding the actual excellent transparency of the crystal. There is a basal fracture about halfway up the crystal (cleavage would be smooth - this flaw looks conchoidal).
