CBJ Assessment and Evaluation 2

Question 1

When evaluating a customer's prong-set stone before repair, what is the FIRST thing a bench jeweler should check?

Accepted Answer

Condition and integrity of each prong tip

Answer

Prong tips must be evaluated first because damaged or thin prongs may break during the repair process, risking stone loss.

Question 2

A customer brings in a yellow gold ring with visible green discoloration in the shank. This most likely indicates:

Accepted Answer

Low karat gold with high copper content reacting to skin chemistry

Answer

Green discoloration in low-karat gold typically results from copper in the alloy reacting with moisture and acids from the skin.

Question 3

Which tool is best used to assess the depth of a bezel setting before resizing the stone?

Accepted Answer

Millimeter gauge (caliper)

Answer

A caliper or millimeter gauge provides precise measurements of bezel depth and diameter necessary for proper stone fit evaluation.

Question 4

During intake assessment, you notice a customer's piece has a hairline fracture in the shank. What is the appropriate next step?

Accepted Answer

Document and disclose the fracture to the customer before any work

Answer

Pre-existing damage must always be documented and disclosed to the customer before work begins to protect both parties and set proper expectations.

Question 5

What is the purpose of using an acid test when evaluating an unmarked piece of jewelry?

Accepted Answer

To determine the approximate karat or metal type

Answer

Acid testing reacts with the metal to indicate its approximate karat or type based on how quickly the acid dissolves the test streak.
