Program Syllabus & Core Modules

Explore the systematic scientific syllabus of the CDG3E2603 block, balancing theoretical knowledge with technical evaluation.

Understand the fundamental properties of light behavior within a diamond's crystal structure and master cleaning and calculation workflows.

  • Diamond Optics & Properties: Advanced study of physical structures, crystallographic characteristics, and light-refraction laws.
  • Systematic Examination: Correctly cleaning gems and executing viewing loops under favorable and unfavorable angles of observation.
  • Principles of Weighing: Operational parameters of hydrostatic balances and formulaic calculation of carat weight.

Acquire high-tier diagnostic grading skills using standard reference markers, comparison master stones, and specialized instrumentation.

  • Clarity Grading Mastery: Utilizing both the standard 10x triplet loupe and gemmological microscopes to analyze internal and external characteristics.
  • Colour Calibration & Fluorescence: Grading colors by comparison with official master stones and evaluating stone reactions to UV fluorescence.
  • Structural Feature Mapping: Developing precise plotting methodologies using standard international symbol systems.

The commercial verification track. Identify proportion angles, evaluate complex modifications, and instantly expose simulants and treatments.

  • Cut, Proportion & Finish Grading: Quantitative calculation of proportions, symmetry parameters, and final polish states using calipers (micrometers) and reference tables.
  • Fancy Cuts Evaluation: Visual and mathematical criteria for assessing pear, marquise, oval, emerald, and princess shapes.
  • Security, Synthetics & Treatments: Disclosing diamond imitations (simulants), crack-filling enhancements, and introducing diagnostic thresholds for lab-grown specimens.
