Q1.
In a shared-prong setting for a round brilliant diamond, which of the following best
describes the correct technique to ensure both security and maximum light return?
A. Use a bur that matches the girdle B. Cut the seats with a hart bur, lower the
diameter to seat the stone deeply, then push stone to the desired height, and use a
the prongs over the crown with a flat graver. beading tool to round the prong tips over the
girdle.
C. Set the stone with a tube bur, then use a D. Drill the prongs with a round bur, seat the
needle file to shape the prongs, and finally stone, and use a knife-edge graver to
burnish the prongs with a polished steel undercut the prongs for maximum metal
pusher. coverage.
Correct: B - Cut the seats with a hart bur, lower the stone to the desired height, and use a
beading tool to round the prong tips over the girdle.
Rationale:A hart bur is specifically designed to cut a precise seat in the prong, matching the
stone's girdle. Lowering the stone to the correct height ensures the girdle is not too high or
low, and beading the prong tips secures the stone while allowing light to enter through the
crown. A flat graver is used for texturing, not rounding prongs, and a tube bur is for tube
settings, not shared prongs.
Q2.
A customer brings in a white gold ring that has developed a yellowish tint. Which of the
following is the most likely cause and the appropriate remedy?
A. The rhodium plating has worn off, B. The gold has become oxidized due to
exposing the natural yellow color of the gold exposure to sulfur; clean with an ultrasonic
alloy; re-plate with rhodium. and apply a jewelry cleaner.
C. The ring is actually yellow gold that was D. The metal has become porous from
white-plated; strip the plating and re-polish repeated polishing; the surface needs to be
to restore the original yellow. re-polished with a high-tripoli compound.
Correct: A - The rhodium plating has worn off, exposing the natural yellow color of the
gold alloy; re-plate with rhodium.

Rationale: White gold is typically alloyed with nickel or palladium and then rhodium-plated to
achieve a bright white finish. Over time, the rhodium wears off, revealing the slightly yellow
base alloy. The correct remedy is to re-plate the ring with rhodium after cleaning and
polishing. Oxidation would cause a dull gray film, not a yellow tint, and porosity is not a
common cause.
Q3.
When sizing a ring with a channel-set diamond band, which of the following is the safest
approach to prevent damaging the stones?
A. Cut the band and solder, then use a B. Use a laser welder to cut and rejoin the
burnisher to tighten the channel walls. band without applying heat to the stones.
C. Heat the entire band with a torch to D. Remove the stones first, size the band,
anneal the metal, then cut and solder as then reset the stones.
usual.
Correct: D - Remove the stones first, size the band, then reset the stones.
Rationale:Channel-set stones are extremely susceptible to heat damage and loosening
during soldering. Removing the stones before sizing eliminates the risk of heat damage and
allows proper access to the channel. A laser welder still generates localized heat that can
affect the stones, and heating the entire band is even worse. Burnishing after soldering does
not protect the stones from heat.
Q4.
In laser welding, what is the primary advantage of using a lower power setting with a
longer pulse duration compared to a high power, short pulse?
A. It creates a deeper weld with less B. It reduces the risk of cracking in
heat-affected zone (HAZ). high-karat gold.
C. It allows for faster welding of thin D. It produces a more visible weld seam for
materials. easier grinding.
Correct: B - It reduces the risk of cracking in high-karat gold.
Rationale:Lower power with longer pulse duration allows the heat to dissipate more gradually,
reducing thermal shock and the risk of cracking, especially in high-karat gold which is softer
and more prone to stress. A high power short pulse creates a shallow weld with a larger HAZ,
which can cause brittleness. Deeper welds are achieved with higher power, but that increases
HAZ.
Q5.
A bench jeweler needs to accurately measure the diameter of a round brilliant diamond to
order a replacement. Which tool provides the most precise measurement?
