Digital Gold & Platinum Tester
QUICK OPERATION GUIDE
Congratulations on your purchase of the advanced AuRACLE PRO digital
gold and platinum tester from GEMORO Superior Instruments, the most
trusted name in testing instrumentation for the jewelry industry.
The following is your testers QUICK OPERATION GUIDE. For
more detailed information on its use, please scan the QR
code or click here to see the INSTRUCTIONAL VIDEO:
STEP 1: POWER ON
Aer the AC adapter and/or batteries are installed, and
the pen probe is fully plugged into the unit, turn the AuRACLE PRO on by
pushing the MODE button. The LCD display will then show “Ready”.
STEP 2: CALIBRATION PROCEDURE
Remove the pen probe cap and wipe any excess solution o the felt tip
with a dry paper towel. Press the CAL button and the display will show
“Touch pen to 18K sample”. File a piece of 18K YELLOW GOLD and place
it on the testing plate, and then touch the pen probe to the filed area. The
display will then quickly show “Success!” when the calibration process has
been completed. Note that this process may need to be repeated 1-2
times. The AuRACLE PRO will then be calibrated and ready to test.
STEP 3: TESTING GOLD AND PLATINUM
• For best results, it is recommended to file a small area on
the surface of the jewelry being tested, and then rest it
on the testing plate with the filed area facing up.
• Touch and hold the pen probe to the filed area until the LCD display
quickly settles on a karat value, Platinum, or Not Gold. It is recommended
to hold the jewelry on the testing plate to stabilize it, and to make
good contact with the pen probe and the metal being tested.
• There are 2 testing modes on the AuRACLE PRO, the
STANDARD MODE and ENHANCED MODE. You can toggle
between each mode by pressing the MODE button.
• ENHANCED MODE - This mode provides the most information for
users, while indicating karat values in 8K, 10K, 14K, 18K, 22K, and 24K,
as well as platinum. It shows the gold karat percentage, along with
an innovative new feature at the bottom of the display, a bar graph
that shows you where in the karat range the gold falls. (Example: if
it is in the low, middle, or high karat value within the 14K range).
• STARDARD MODE - This is the factory set default mode,
which gives the same information as the ENHANCED

EASY OPERATION GUIDE & OWNERS MANUAL 
MODE, but without showing the percentage feature.
• The AuRACLE technology is calibrated to yellow gold. Due to inconsistencies
in the types and percentages of alloys used in producing white gold
(silver, nickel, etc.), it potentially may test slightly lower than marked.
• When you are finished testing, always replace the pen probe
cap until it snaps on to prevent it from drying out.
STEP 4: PRO POWER OFF
To turn the AuRACLE PRO o, press and hold the MODE button.
The tester also has an auto-o feature when using battery power
and will automatically turn itself o in 10 minutes if not used.
AuRACLE PEN PROBES ARE NOT INTERCHANGEABLE. ONLY
USE THE “GOLD LABEL” AuRACLE PRO REPLACEMENT
PEN PROBES WITH THIS DEVICE (Item #2018).

DETAILED OPERATION INSTRUCTIONS
. BATTERY AND AC ADAPTER INSTALLATION
Install a 9V alkaline battery (not included) as follows. First, always be mindful that
the AuRACLE PRO is a delicate instrument and can be broken if it is not handled
with care. Open the battery compartment door located on the bottom side of
the unit by pressing and then sliding the battery compartment door o with your
thumbs. Remove the battery connector and attach a 9V alkaline battery to it
with the direction of the positive (+) and negative (-) polarity correctly positioned.
Reinsert the battery and wiring back into the compartment so that the door may
be replaced. Replace the battery compartment door. To conserve the battery
life, be certain to always power down the AuRACLE PRO when not in use.
. POWERING ON / OFF
The AuRACLE PRO may be powered by either its AC adapter or a 9V alkaline
battery. When an AC adapter is installed the AuRACLE PRO will automatically be
powered by it while preserving the battery life. Alternatively, if no AC adapter is
being used and the battery is installed, the tester will be powered by it. To power
on the AuRACLE PRO simply press the Power/Mode button. When the unit is
powered on, it will run through a quick boot sequence (“AuRACLE PRO” will show
on the display) and then will default to the “Standard Mode” setting. To power
o the AuRACLE PRO press and hold the Power/Mode button for more than two
seconds. The display will show a 5 second count down timer. When the timer
reaches zero then it will power o. Pressing either button during the countdown
will abort the process and return the AuRACLE PRO to normal operation.

. LOW BATTERY INDICATION
When the battery power drops to a low level, a “B” will start flashing
on the upper right side of the display indicating that a new battery
should quickly be inserted to ensure maximum testing accuracy.
. MODES OF OPERATION
The AuRACLE PRO has two testing modes of operation that
are described below. Press the Power/ Mode button to toggle
between these modes: Standard Mode and Enhanced Mode.
ENHANCED MODE
This mode provides the most information for users, while indicating karat
values in 8K, 10K, 14K, 18K, 22K, and 24K, as well as platinum. It shows the
gold karat percentage, along with an innovative new feature at the bottom of
the display, a bar graph that shows you where in the karat range the gold falls.
(Example: if it is in the low, middle, or high karat value within the 14K range).
STANDARD MODE
This is the factory default mode, which gives the same information as
the Enhanced Mode, but without showing the percentage feature.
SMART TWO BUTTON CONTROL FUNCTIONS
Power/Mode Button (Le) Pressing this button will toggle between
the two operating modes, Standard Mode, and Enhanced Mode.
Pressing this button for more than two seconds will initiate the
unit’s 5 second shut down timer. Pressing any key before the timer
reaches zero will return the AuRACLE PRO to normal operation.
CAL BUTTON (Right) By pressing this button the pen probe calibration process
will be initiated. The AuRACLE PRO must be calibrated with an 18K yellow
gold sample. Only yellow gold may be used to calibrate this instrument.
PEN PROBE CALIBRATION Before using the AuRACLE PRO, it must be
calibrated to the pen probe being used. It is important to recognize that the
chemistry in each pen probe is slightly dierent and that it is constantly
changing over time as it is exposed to gold and other metals, contaminants, the
environment, and dirt. As the chemistry in the pen probe changes it may become
necessary to recalibrate the AuRACLE PRO to the pen probe’s chemistry at that
time, which is simple to do. You must use an 18K yellow gold sample to calibrate
the tester, and we recommend that the gold calibration piece be filed just prior
to doing so. A short press of the CAL button will initiate the calibration process.
The calibration process can be performed in either operating mode at any time
and will return to that mode once complete. When initiated, a countdown timer
will appear on the lower line of the LCD display. Place the gold you are using to
calibrate the AuRACLE PRO on the testing plate with the filed area facing up.
Steadily touch the end of the pen probe’s felt tip to the filed area on the gold
and once the process has been completed the LCD display will read “Success!”.

EASY OPERATION GUIDE & OWNERS MANUAL 
Note that this process may need to be repeated 1-2 times. The tester will wait
approximately 8 seconds for the pen probe to touch the gold calibration sample
and if this is not done within that period the process will be aborted. Once the
pen probe touches the gold sample, the AuRACLE PRO will quickly monitor the
readings and wait for stability before it will be considered a successful calibration.
If the pen probe’s reading doesn’t stabilize within 20 seconds, the operation
will fail and abort. A failed calibration may indicate a defective pen probe.
ADDITIONAL INSTRUCTIONS
USE COMMONSENSE BEFORE INTERPRETING THE TEST RESULTS. You
should always follow some commonsense guidelines before making your final
determination of the karat value or authenticity of the precious metal being
tested. Please keep in mind that those misrepresenting fake jewelry as real
can be extremely clever and will use many tricks to make you think it is real.
GUIDELINE A. Check the markings on the piece for a karat stamp (10K or .417,
14K or .585, 18K or .750, 22K or .916, 24K or .999, GF or gold-filled, GEP or gold
electroplated, YGF or yellow gold-filled, RGP or rolled gold plated, etc.). If the test
results indicate anything dierent than the stamp, the metal should be suspect.
GUIDELINE B. Check the weight of the metal you are about to test and if it
seems too light, while it could be hollow gold, it should be suspect as it may be
costume jewelry, gold-plated or gold-filled. Gold is a dense metal and has an
associated greater weight than most other non-precious metals. Platinum is
an even denser metal than gold, while weighing approximately 1/3 more than
18K gold. Be aware that tungsten/stainless steel is also a dense metal, and that
oen times it may be used at the core of the jewelry, under a layer of gold.
GUIDELINE C. Check the color of yellow gold and be aware that non-gold
base metals are oen flashed or gold-plated with 24K gold to enhance its
color and consequently the gold color will look too yellow. Since 24K gold
is a rich yellow color and this pure gold is very uncommon in jewelry, any
rich yellow gold color should be suspect. Look for tarnishing or variations
in the color and finish of the jewelry as a sign of it being a fake.
GUIDELINE D. Check the clasp used on the jewelry. Costume jewelry oen
has a spring ring style clasp, and this should be suspect. Karat jewelry oen
will have a lobster style clasp. Do not test the clasp only as it is common for a
karat gold clasp to be attached to a fake gold necklace or bracelet to fool you.
TROUBLESHOOTING & HELPFUL TIPS
The AuRACLE PRO should always be calibrated before using. It may also be
necessary to recalibrate it as needed. Also, periodically wipe the pen probe’s
felt tip on a dry paper towel to clean it if inconsistent results are experienced.

GEMORO AuRACLE®PRO Digital Gold & Platinum Tester 
IT IS IMPORTANT TO RECOGNIZE THAT THE CHEMISTRY IN THE PEN PROBE
IS CONSTANTLY CHANGING OVER TIME AS IT IS EXPOSED TO GOLD AND
OTHER METALS, CONTAMINANT’S, THE ENVIRONMENT AND DIRT. The
genius of the AuRACLE technology is that by wiping the pen probes felt tip on a
dry paper towel to clean it, and then recalibrating the AuRACLE PRO periodically,
this allows the tester to adjust itself to the chemistry in the pen probe at that
time. Since the AuRACLE PRO can be calibrated in only a matter of seconds and
the pen probe’s felt tip may be quickly and easily cleaned when needed, these
simple steps should be a regular part of your testing and problem-solving process.
If the AuRACLE PRO will not calibrate, the pen probe may be defective, spent
or in need of replacement. Please note that it is recommended for best results
that you should consider replacing the pen probe if it is excessively worn or
becomes overly dirty from repeated exposure to costume jewelry, fake gold
or other contaminates. A pen probe in this condition may begin to deliver
erratic readings and these are good indicators that it should be replaced.
REGULAR CLEANING OF THE PEN PROBE’S FELT TIP AND TESTING PLATE:
Always use a dry paper towel to wipe o the gold particle filings and other
metal particles coming from costume, gold-plated or gold-filled jewelry
that may remain on the pen probe’s felt tip to avoid contamination. The
metal particles remaining on the pen probe’s felt tip that are naturally
rubbed o during the testing process, and especially metal filings from
other karat gold, copper, brass, or other base metals that have been
filed and remain on the pen probe’s felt tip could potentially cause
incorrect test results. Therefore, regular cleaning is important.
The pen probe contains a special saline solution that is safe, non-acidic, and non-
toxic. Remove salt crystal buildup by dabbing the pen probe’s felt tip with a clean
and dry paper towel. Salt crystal buildup is a natural occurrence with this device.
While using a dry paper towel, wipe o any salt crystal buildup from the 18K
yellow gold calibration piece and the AuRACLE PRO testing plate area. Be aware
that the pen probe solution may potentially leave a stain on the testing plate if
not wiped o immediately aer it makes contact, so cleaning it right aer this
occurs is advised. While this staining may occur, it will not impact the accuracy
of the AuRACLE PRO. Never expose the pen probe’s felt tip to water or other
chemicals. Always replace the pen probe cap until it snaps on when not in use.
FOR BEST RESULTS FILE ALL METAL BEFORE
TESTING AND CLEAN THE FILE:
The AuRACLE PRO is a surface tester, so consequently the tester may
test gold-plated and gold-filled as solid gold if not filed to expose the
base metal. Depending on the thickness of the gold on the surface of the
jewelry, cutting or sawing through the surface may be required to expose the
base metal. Gold, platinum, gold-plated, gold-filled, tungsten and stainless

EASY OPERATION GUIDE & OWNERS MANUAL 
steel must be filed below the surface before testing to produce accurate
results. Always wipe o the file aer use. Be aware that gold and other
metal particles on the file could cause contamination from the metal to
spread to the next piece you are testing if it is not regularly cleaned o.
NO REACTION WHEN TESTING:
This is an indication that either the pen probe isn’t plugged
into the AuRACLE PRO all the way or that the material you
are testing is non-conductive (example plastic).
TEST RESULTS ARE TOO HIGH:
This is an indication that the AuRACLE PRO is out of calibration, or perhaps there
is a high presence of silver, palladium, or rhodium on the gold you are testing.
OTHER PRECIOUS METALS
TUNGSTEN AND STAINLESS STEEL:
Be aware that if tungsten or stainless steel isn’t filed first it may
test in the high karat range or even as platinum, but if it is filed
it will then test as Not Gold. ALWAYS FILE IT FIRST!
RHODIUM:
Be aware that rhodium will react as platinum on the AuRACLE PRO. It
is rarely used as solid finished jewelry, but instead it is commonly used
as a plating material to make white gold or platinum appear brighter
or whiter. If white gold is plated with rhodium and filed, it will then test
accurately or possibly as a higher karat than marked since it is taking
an average reading of the two metals. ALWAYS FILE IT FIRST! If white
gold tests higher than marked, it is probably rhodium plated.
PALLADIUM:
Be aware that pure palladium will test somewhere between 18K and 24K on
the AuRACLE PRO. In the case of palladium being mixed with white gold, it will
drive the reading up to a higher karat than it is. If you see a reading on white
gold that is higher than marked, it may very well be mixed with palladium.
WHITE GOLD WITH HIGH NICKEL OR HIGH SILVER CONTENT:
Be aware that white gold with a high nickel content may test as a
lower karat than marked. While it could be under karat gold in this
instance, it is likely the karat marked. White gold commonly has a
4% to 7% silver content. If white gold has a higher silver content
above 7% it may test as a slightly higher karat than marked.
