Inclusion Plotting
Inclusion Plotting is a quality control process in diamond assessment where specialists map out the internal features (called inclusions) inside a diamond. Think of it like creating a 3D map showing any tiny crystals, clouds, or marks inside the diamond. This helps diamond cutters decide the best way to cut and shape the stone to either hide these features or work around them to get the best value from the diamond. It's similar to how a carpenter might mark knots in wood before cutting, but much more precise and done with special imaging equipment.

Example Interview Questions
Senior Level Questions
Q: How do you handle complex inclusion patterns when planning a diamond cut?
Expected Answer: Should explain their process for analyzing multiple inclusions, considering their impact on final value, and making strategic cutting decisions that maximize the diamond's worth while maintaining quality standards.
Q: How do you train new plotters and ensure consistency in team assessments?
Expected Answer: Should discuss training methods, quality control procedures, and how they maintain standards across different team members when analyzing diamonds.
Mid Level Questions
Q: What factors do you consider when deciding whether to plot an inclusion?
Expected Answer: Should explain how they determine which inclusions are significant enough to plot, considering size, position, and impact on diamond value.
Q: How do you use plotting software to maximize diamond yield?
Expected Answer: Should demonstrate understanding of how plotting technology helps in planning cuts and managing quality control.
Junior Level Questions
Q: What are the basic types of inclusions you look for when plotting?
Expected Answer: Should be able to list and describe common inclusion types like crystals, clouds, feathers, and explain how they're marked on plots.
Q: What safety procedures do you follow when handling diamonds?
Expected Answer: Should describe basic diamond handling protocols, security measures, and documentation procedures.
