Beautiful gemstone reference book, “Gemstones of the World” by Walter Schumann (hardcover). I thoroughly enjoyed this book and it’s time for a new home! "Gemstones of the World" is the single, cornerstone volume that every hobbyist, jeweler, jewelry maker, and rockhound needs. More than 1,500 full-color photos showcase each precious and semiprecious stone in its rough, natural, polished, and cut renditions. Each entry offers complete information on the gemstone’s formation, structure, physical properties, and characteristics. Smoke-free home. Please let me know if you have any questions. Thank you!
