This is a large Aqua specimen. It weighs 642 grams (1 pound 6.65 ozs). It has four large crystals and seven or eight smaller crystals. It has great color, and a bright, reflective surface. I've pictured the interpenetration of the central 5 cm crystal with a smaller aqua that terminates in the center of the host crystal. No visible damage, there is some contact along the sides.
