ACTUAL EXAM COMPLETE 180 QUESTIONS AND CORRECT
DETAILED ANSWERS
Question 1
What is the primary purpose of a diamond grading system?
A) To determine a diamond's monetary value precisely.
B) To allow gemologists to identify synthetic diamonds.
C) To provide a consistent way to communicate diamond quality.
D) To classify diamonds based on their origin.
E) To ensure diamonds are ethically sourced.
Correct Answer: C) To provide a consistent way to communicate diamond quality
Rationale: A diamond grading system establishes a standardized language and set of
criteria, ensuring that diamond quality can be described and understood uniformly
across the industry.
Question 2

A) Sells diamonds directly to the end consumer.
B) Sells to retailers.
C) Mines raw diamond rough.
D) Cuts and polishes rough diamonds.
E) Appraises diamonds for insurance purposes.
Correct Answer: B) Sells to retailers
Rationale: A wholesaler acts as an intermediary, purchasing diamonds in bulk and
then selling them to retailers who, in turn, sell to the public.
,Question 3
What primarily influences the diamond prices found on wholesale price lists?
A) The age of the diamond.
B) The specific retailer's markup.
C) The market conditions existing at the time of publication.
D) The country of origin for the diamond.

Question 4
How does the grading process typically differ for large, high-quality diamonds compared to
small, low-quality ones?
A) Small, low-quality diamonds are graded more extensively to find any hidden value.
B) Both types of diamonds receive the same level of grading scrutiny.
C) Large, high-quality diamonds are graded much more thoroughly.
D) Only large diamonds are graded, small ones are sold ungraded.
E) Low-quality diamonds are graded by machines, high-quality by hand.

precision in their assessment.
, Question 5
What accounts for diamond's supreme hardness and durability?
A) Its unique chemical composition (pure carbon).
B) Its ability to reflect light intensely.
C) The high-pressure, high-temperature conditions under which it formed.
D) Its crystalline structure being perfectly symmetrical.
E) The rapid cooling process during its formation.
Correct Answer: C) The high-pressure, high-temperature conditions under which it
formed.
Rationale: The extreme conditions deep within the Earth, involving immense
pressure and high temperatures, are responsible for the incredibly strong atomic
bonds that give diamond its unparalleled hardness and durability.
Question 6
After diamond deposits are located, what must mining companies typically do next?
A) Immediately begin large-scale extraction.
B) Secure international patents for the deposit.
C) Must spend additional time and money to evaluate and develop them.
D) Negotiate directly with jewelers for sales.
