"Magnetism in gemstones is an often-overlooked but fascinating aspect of gemology. Discover how certain gemstones, like garnets, react to magnets due to their magnetic metals, and learn why treated stones, such as color-enhanced tourmaline, behave differently. You'll also get insights into diamagnetism in stones like blue feldspar, which uniquely repels magnets! Whether you're a gem enthusiast or a professional, understanding magnetic traits adds a whole new dimension to gemstone beauty and identification."
