A 10x loupe magnifies the viewed image to appear ten times its actual size, allowing detection of fine surface flaws.

Question 2

Which of the following is a sign of poor solder flow in a bezel setting?

Accepted Answer

Pitting or voids visible at the solder seam

Answer

Pitting or voids at a solder seam indicate incomplete solder flow, often caused by insufficient heat or contamination.

Question 3

When quality-checking prong tips on a claw setting, which defect is most likely to cause stone loss?

Accepted Answer

Prongs that are undercut or too thin at the tip

Answer

Undercut or excessively thinned prong tips lack the metal needed to securely hold the stone and are prone to breaking.

Question 4

What is the primary purpose of performing a flex test on a ring shank?

Accepted Answer

To detect weak solder joints or metal fatigue

Answer

A gentle flex test applies stress to the shank to reveal any hidden solder failures or thinned areas before the piece leaves the bench.
