Putting the four Cs together

Lesson quiz · five questions, in a new order every time

Five questions on lesson 8 of The four Cs. The questions and the answers to pick from come in a new order every time you start.

Pick an answer, and the question marks itself. For a question that you answer in your own words, think of your answer first. Then show our answer and say whether you had it. Nothing is saved or sent.

  1. Question 1: Which one probably looks better face up?

    Show the answer

    b: Cut decides how the face handles light, and the Poor stone is even smaller.

  2. Question 2: A buyer wants a bigger stone for the same budget. Which step down usually costs the least in looks?

    Show the answer

    b: Near-colorless grades look white face up; a weaker cut changes the whole face.

  3. Question 3: Why can a 0.99 ct stone be a smart buy?

    Show our answer

    It's 0.02 mm narrower than a 1.00 ct, and nobody can see that. Its price is usually much lower than the round number.

  4. Question 4: Under warm home light, the color difference between a G and a K gets smaller. Does the cut difference between Excellent and Good get smaller too?

    Show our answer

    No. Warm light tints both stones the same way; the leakage and the pattern stay.

  5. Question 5: True or false: a Z color is a bad diamond.

    Show our answer

    False — it has a visible tint; some people choose exactly that.
