When sizing a ring down using the cut-and-weld method, where should the jeweler make the cut?

The cut is made at the bottom of the shank to preserve symmetry and keep any solder seam away from visible areas.
Which torch tip size is most appropriate for soldering a delicate platinum grain-set band?
Answer: A fine tip for precise, controlled heat
A fine tip delivers precise, controlled heat to the small work area without overheating adjacent grain-set stones.
A customer's yellow gold chain has a broken link. Which repair technique restores the most strength to the link?

When tightening a loose prong on a pavé-set ring, which tool minimizes the risk of chipping the small stones?
Answer: A prong pusher with a polished cup tip
A prong pusher with a polished cup tip provides controlled pressure over the prong tip, reducing chip risk on small pavé stones.
Which alloy characteristic makes white gold more prone to cracking during cold working than yellow gold?
Answer: Nickel or palladium alloying metals reduce ductility
Nickel and palladium used to decolorize gold reduce its ductility, making white gold more susceptible to cracking during cold working.
A bench jeweler needs to open a jump ring cleanly without distorting it. What is the correct motion?
Answer: Twist one end forward and one end backward in opposite directions
Twisting the ends in opposite directions (front-to-back) opens the ring without distorting its circular shape, allowing it to close cleanly.
