Mastery: developing (Level 2)(based on Certificate)

  • Loupes, shadowgraphs, and microscopes — apply routinely to examine gem processing accuracy and confirm cut angles meet quality standards with minimal oversight.
  • Polish, symmetry, and clarity grading scales — assign grades independently to common stones using established grading systems in a production or retail setting.
  • Wholesale and retail gem values — estimate with confidence by consulting current pricing guides and tracking market fluctuations for standard gem varieties.
  • Optical instruments including polariscopes and refractometers — use proficiently to differentiate between familiar stone types and detect common internal defects.
  • Plot diagram documentation — produce accurate clarity characteristic records for a range of stones, flagging unusual inclusions for senior review.
  • Color discrimination and visual grading — apply calibrated visual color assessment to sort and grade gems consistently across a full production shift.
  • Customer consultations on gem selection — conduct with active listening and clear speaking to help clients choose appropriate stones for jewelry applications.
  • Analytical or scientific software — input gem examination data and generate standard reports in support of grading and quality control workflows.
  • CAD software for jewelry design reference — review gem dimensions and proportions within design files to confirm stone suitability for setting specifications.
  • Inventory and accounting software — maintain up-to-date gem lot records and assist with pricing calculations as part of routine operational duties.
