  1. When educating customers about diamond insurance, a GIA professional should recommend insuring a diamond for which value?

    Answer: The replacement value based on a current independent appraisal

    Insurance should be based on the current replacement value from an independent appraisal, which reflects what it would cost to replace the item today.

  2. How should a GIA-certified diamond be stored when not being worn to prevent damage?

    Answer: In an individual soft-lined pouch or separate compartment to prevent diamonds from scratching each other

    Diamonds can scratch other diamonds and softer gemstones, so each piece should be stored separately in a soft-lined compartment.

  3. What is the primary reason GIA advises consumers to keep their diamond grading report in a safe location?

    Answer: The report serves as documentation for insurance, resale, and verification of the diamond's identity and quality

    The GIA grading report is the primary document that verifies the diamond's quality characteristics and is essential for insurance claims and resale transactions.

  4. A customer notices their diamond looks dull and lacks sparkle. Before recommending professional cleaning, what is the most common cause of this issue a GIA professional would identify?

    Answer: A buildup of oils, lotions, and skin residue on the diamond's surface is blocking light entry

    Daily lotions, soaps, and skin oils form a film on the diamond's surface that significantly reduces light return and apparent brilliance.

  5. What information should a consumer record immediately after purchasing a GIA-certified diamond to assist with identification in the event of theft or loss?

    Answer: The GIA report number, 4Cs details, and ideally a photograph of the stone and its report

    Recording the GIA report number and full grading details, along with photographs, creates a unique identity record that can help law enforcement and jewelers identify a recovered stone.

  6. Why is it important for consumers to understand the difference between a diamond's 'hardness' and its 'toughness'?

    Answer: Diamonds are the hardest mineral but can still chip or cleave along crystallographic planes when struck sharply

    While diamonds rank 10 on the Mohs hardness scale, their perfect cleavage in four directions means a sharp blow can cause chipping or fracture.
