MCQ Detailed View

The value of a diamond is traditionally determined by the 5 Cs. These are Carat, Cut, Clarity, Color, and Certification. The option Composition is not part of the 5 Cs, which makes it the correct answer to this question.

Explanation of the 5 Cs:

• Carat Weight: This refers to the weight of the diamond. One carat equals 200 milligrams. Larger diamonds are rarer and more valuable.


• Cut: The cut does not mean the shape, but how well the diamond has been cut and polished. It directly affects how much the diamond sparkles and reflects light.


• Clarity: Clarity measures the presence of internal flaws (inclusions) or external blemishes. The fewer the imperfections, the higher the clarity and value.


• Color: Diamonds are graded based on their color, or more precisely, the lack of it. The most valuable diamonds are colorless, graded from D (colorless) to Z (light yellow or brown).


• Certification: A diamond’s quality is verified by certification from a recognized gemological laboratory, such as GIA (Gemological Institute of America). This document confirms the stone’s characteristics and authenticity.

Why not Composition?
The option Composition is not considered in diamond valuation. Almost all natural diamonds are made of carbon, so composition does not distinguish one stone’s value from another. Instead, the internationally recognized system focuses on the 5 Cs listed above.

Conclusion:
The 5 Cs are a universal standard for evaluating diamonds: Carat, Cut, Clarity, Color, and Certification. Therefore, the correct answer is Composition, as it is not included in the 5 Cs.
