Clarity Plotting
Clarity Plotting is a fundamental skill in the jewelry and gemstone industry where professionals create detailed diagrams or maps of a gemstone's internal and external characteristics. It's like creating a detailed medical chart but for precious stones, showing where inclusions (internal features), blemishes (external marks), or other identifying features are located. This documentation is crucial for diamond grading, identification, and valuation. The practice helps jewelers and gemologists track stones, verify their identity, and assess their quality. You might also see this referred to as "Diamond Plotting" or "Stone Mapping" in job descriptions.
