Seen at the 2017 Tucson Gem and Mineral Show, Hotel Tucson City Center, room 323 (Suzanne Morrison, Raining Rocks).
From the MetBul:
Single stone; saw-cut surfaces show a green-gray-colored, diabasic texture, with elongate pyroxene crystals set in a finer matrix of maskelynite laths. Some sections show up to ~30%, by volume, black, shock melt pockets, many with mm-sized vesicles.
