“Specimen of antigorite (based on hardness) that may be the variety sometimes called "marmolite", reflecting its laminated structure and pearly luster. The color varies from apple green to black to rusty brown. Magnetite also makes up a significant part of this sample, which exhibits slickenlines on all surfaces. Another old specimen I collected as a 13-year-old with my mentor Ron Januzzi and my parents. ”
