What is the term for the process of distinguishing natural minerals and gems from each other as well as from synthetics, simulants, and treated gems?

• A. Separation
• B. Sorting
• C. Grading
• D. Identification

Answer: (A)

Identifying is about determining exactly what the gem is and where it comes from, including whether it is natural, synthetic, a simulant, or has undergone treatment. This involves analyzing diagnostic features such as refractive index, birefringence, spectral data, inclusions, and growth patterns to establish the gem’s identity and origin. Separation means physically moving materials apart, sorting is organizing items, and grading focuses on quality attributes like color, clarity, and cut—not on determining what the gem actually is or whether it’s natural, synthetic, a simulant, or treated. So the process described is identification.
