Professional Standards & Competencies Flashcards

Which of the following best defines the professional standard of 'due diligence' in diamond grading?

Answer: Thoroughly applying all required tests, observations, and documentation protocols to each stone

Due diligence means rigorously applying every required grading procedure and documentation standard to ensure accurate, defensible results.

A grader disagrees with a senior grader's final grade determination on a stone. The appropriate professional response is to:

Answer: Document the disagreement through proper internal channels and escalate if necessary

Professional disagreements should be resolved through established internal escalation channels, not unilateral action or client disclosure.

The FTC Guides for the Jewelry, Precious Metals, and Pewter Industries are most relevant to diamond graders because they:

Answer: Require disclosure of treatments, synthetics, and prohibit misleading trade terms

FTC Guides govern disclosure of treatments and synthetic origin and prohibit deceptive terminology in trade, directly affecting how grading reports must be worded.

A professional diamond grader should recuse themselves from grading a stone when:

Answer: They have a financial interest in the stone's grade outcome

A financial interest in the grading outcome creates an irreconcilable conflict of interest that requires recusal to protect objectivity.

Quality assurance in a professional grading laboratory typically involves:

Answer: Systematic re-grading of a random sample of stones to verify grader consistency

Random sample re-grading is the standard QA mechanism for detecting grader drift and maintaining consistent standards across the laboratory.

When handling a diamond worth over $100,000 in a professional laboratory, security protocol typically requires:

Answer: Enhanced chain of custody documentation and dual verification at each transfer point

High-value stones require enhanced documentation and dual verification at each transfer to minimize risk and maintain accountability.

A grader who observes what appears to be a synthetic moissanite submitted as a diamond should:

Answer: Test it with a thermal and electrical conductivity tester, then report findings accurately

Confirmatory testing with appropriate instruments and accurate reporting of findings are required professional obligations regardless of how a stone was submitted.
