" What treasures they left behind! A gorgeous set of yellow topaz crystals on a gray matrix. A great pink hunk of beryl like a crystallized brain. A violet column of tourmaline from Madagascar that looks so rich he cannot resist the urge to stroke it. Bournonite; apatite on muscovite; natural zircon in a spray of colors; dozens more minerals he cannot name. "
