Directions for : Read the following paragraph:
(I) The clarity of the stone is determined by its lack of carbon spots, surface flaws and blemishes.
(II) While these are hardly seen with naked eyes, it affects diamond’s brilliance.
(III) The most commonly found quality of diamond is VVSI (very very slightly imperfect), flawless as one can find.
(IV) The quality goes on improving in VVSI, VVS2, and so on.
Which of the following is true about clarity of stone :
Explanation
The correct option is (b) It is determined by its imperfection.
Detailed Solution
To identify the correct statement regarding the clarity of the stone, let us analyze the premises provided in the text:
Statement (I) states:
"The clarity of the stone is determined by its lack of carbon spots, surface flaws and blemishes."
Carbon spots, surface flaws, and blemishes are structural anomalies or imperfections in a gemstone.
Therefore, saying clarity is determined by the lack of these features is logically equivalent to saying that clarity is graded and evaluated based on its imperfections (i.e., fewer imperfections mean higher clarity).
Let's evaluate the given choices:
(a) is incorrect because a high-clarity stone does not necessarily have carbon spots, flaws, and blemishes; clarity is defined by their absence.
(b) is mathematically and logically sound because the magnitude of structural imperfections directly determines the grade of clarity.
(c) contradicts Statement (I).
Conclusion
Clarity∝Imperfections1
Since imperfections (spots, flaws, blemishes) are the benchmark metrics used to judge clarity, Statement (b) is the true statement.
