Gem identification is the process of determining the type and quality of gemstones. This involves examining various characteristics such as color, clarity, cut, and carat weight. Tools like a loupe or microscope are often used to enhance the examination, allowing gemologists to identify specific features that distinguish one gemstone from another. In addition to visual inspection, gem identification may also involve instrumental methods, such as spectroscopy and refractometry. These techniques help in analyzing the chemical composition and physical properties of the gem, ensuring accurate identification and valuation. Proper gem identification is crucial for both collectors and jewelers alike.
