Jim Magnuson:
Jim Magnuson has been an active student and hunter of a wide range of rocks, minerals, and fossils since he was a child. He has traveled to many locations to hunt for unique, beautiful, and often valuable gifts of nature. Jim enjoys connecting and meeting with local rock hounds and prospectors, listening to their stories, and learning from their experiences. But for Jim, there is nothing like the thrill of being out in the field seeking quality specimens. He confesses that sometimes he gets “skunked,” but this only fuels the passion and desire to achieve success. Jim loves to study relevant geology and paleontology and to perform various work on rocks and minerals for display or jewelry-making. He likes to share his experience—through writing, as well as conducting hands-on presentations and workshops—and help others develop their knowledge, passion, and skill. Jim’s published works include The Storied Agate; The Fairburn Agate of the Black Hills; Agate Hunting Made Easy; Lake Superior Agates; Emma’s First Agate; and Gemstone Tumbling, Cutting, Drilling, and Cabochon-Making.
