  1. A customer brings in a 14k yellow gold ring that needs to be sized down three sizes. Which method is most appropriate?

    Answer: Cut and solder the shank

    Sizing down requires cutting a measured section from the shank and soldering the ends together for a proper fit.

  2. When setting a round brilliant diamond in a four-prong Tiffany-style setting, which step should be done FIRST?

    Answer: Seat the stone in the prongs at equal depth

    The stone must be seated evenly at the correct depth in all prongs before any bending or tipping begins.

  3. You notice flux has become glassy and brown during a soldering operation. This indicates:

    Answer: The flux is exhausted and the joint may oxidize

    Brown, glassy flux indicates it has burned off and can no longer protect the metal from oxidation.

  4. A bench jeweler is asked to remove a bezel-set cabochon from a sterling silver pendant without damaging the stone. The best approach is to:

    Answer: Carefully open the bezel wall with a burnisher or bezel pusher working around the perimeter

    Gently prying the bezel wall outward evenly around the perimeter releases the stone without heat or cutting damage.

  5. When soldering a jump ring closed on a delicate chain, which torch tip and flame type is most appropriate?

    Answer: Small tip with a soft, bushy reducing flame

    A small tip with a soft reducing flame delivers controlled heat and protects the chain links from excessive oxidation.

  6. A channel-set anniversary band has a loose stone rattling in one channel. The correct repair procedure is to:

    Answer: Carefully tighten the channel walls using parallel pliers, then re-check all stones

    Using parallel pliers to gently compress the channel walls closes the gap while preserving the setting integrity.

  7. After casting a wax model in sterling silver, the casting shows large porosity pockets. The most likely cause is:

    Answer: Flask temperature too high at time of injection causing gas entrapment

    Overheating the flask causes gas to become trapped in the solidifying metal, creating porosity voids.
