Phase Identification
Phase Identification is a fundamental skill in gemology where experts determine whether a gemstone is natural, synthetic, or treated. It's like being a detective for precious stones - examining their physical and optical properties to confirm their authenticity and quality. This process helps gemologists distinguish between real gems and imitations, which is crucial for accurate pricing and certification. Think of it as quality control for jewelry stores and gem traders, ensuring customers get exactly what they're paying for.
