features enhanced testing abilities, sleek
ergonomics and more!
OPERATING PROCEDURE
& OWNERS MANUAL
Congratulations on your purchase of
the PRO-D 3 from GemOro Superior
Instruments, the most trusted name
in gemological instrumentation for the
jewelry industry. You’ve made a great
choice. Built upon the foundation of the
second generation and most popular
diamond tester to date, the PRO-D
3 offers even more. Separate true
diamonds from white sapphire, CZ, and
other known diamond simulants with
confidence.
IMPORTANT: PLEASE BE CERTAIN
TO READ THE FOLLOWING
COMPLETELY BEFORE USING.
THERMAL CONDUCTIVITY &
ELECTRICAL CONDUCTIVITY
TESTING METHODS
The recognized method for separating
diamond from all known diamond
simulants (except moissanite and
synthetic diamond) is the thermal
conductivity test. The thermal
conductivity test works consistently well
since a diamond’s heat conductivity
property is significantly greater than all
other gemstones (except moissanite
and synthetic diamond). White sapphire
is also thermally conductive, yet not as
conductive as diamond and moissanite,
therefore, it can be separated from those
two types of stones.
The GemOro Superior Instruments
PRO-D 3 utilizes the thermal conductivity
test and it will quickly help in identifying
and separating the stone in question.

The PRO-D 3 is an advanced,
technologically based tool.
IMPORTANT DISCLAIMER: The PRO-D
3 is a helpful screening tool that by
design is to be used as a quick method
for helping to identify diamonds. The
PRO-D 3 should not be used as the final
method for determining the authenticity
or identity of the gemstone being tested.
The final determination of the identity
of any gemstone, whether genuine or
not, should only be made by a trained
gemologist. Neither GemOro nor any
of its affiliates, dealers, or distributors
shall be held liable for any loss and/
or damages associated with the use
of the PRO-D 3. No warranties exist
with respect to the PRO-D 3 or its use
other than those expressly contained
herein. All other warranties of any kind or
character whatsoever, whether expressed
or implied, including warranties of
merchantability or fitness for a particular
purpose, are hereby disclaimed and are
excluded from the warranties hereunder.
In the event that a claim is made with
respect to the PRO-D 3 or its use, the
maximum liability of GemOro, and its
affiliates, dealers, and distributors shall
be the amount paid for the PRO-D 3.
PLEASE READ BEFORE USING THE
PROVIDED NiMH RECHARGEABLE
BATTERIES: Before using the NiMH
rechargeable batteries that have been
provided with your tester, the batteries
should be fully charged as indicated by
the small round LED indicator next to
the power button glowing green when
the PRO-D 3 is plugged in. While the
batteries are being charged, the tester
may be used as desired while powered
by the AC current.
GEMORO PRO-D 3 4
CONDITIONS FOR IDEAL OPERATION
1. The PRO-D 3 should be used in the
following environmental conditions.
Both the tester and the stone being
tested must be the same temperature.
By not following these instructions you
risk compromising the accuracy of the
test.
a. Temperature: 65°F-80°F (18°C-27°C)
b. Air Relative Humidity: 45%-75%
2. The stone being tested must be dry. If
the surface of the stone is wet or has
any type of surface moisture it may not
test correctly.
3. The stone being tested must be
clean. Aside from obvious visible dirt
that may be present on the stone,
there may also be hand oil or other
contaminates on the stones surface
that may not be visible and which
could impact the accuracy of the test.
Always be certain to clean the stone
being tested with an ultrasonic or
steamer or other appropriate means,
and thoroughly dry it and/or remove
any cleaning chemicals remaining on
the stone prior to testing.
4. It is imperative that the probe tip be
cleaned regularly or ideally prior to
performing a test. Please be aware
that there may be hand oil or other
contaminates that may not be visible
on the probe tip, which could impact
the accuracy of the test. To clean the
tip, take a piece of uncoated white
printer or copy paper and place the
probe tip of the tester at a 90 degree
angle against the paper while gently
rubbing it in a forward motion a few
times. Repeat this process routinely or
prior to testing each time to ensure the
cleanliness of the probe tip.

5. Always allow the stone being tested
to cool off for 5-10 seconds prior to
retesting. Blowing on the stone is
recommended and will speed up this
process. Please be aware that if while
testing a stone the Pro-D 3 light pipe
turns pink, unless it is a white sapphire
or sapphire watch crystal, odds are
that the stone has been overheated
from prolonged exposure to the probe
tip and, therefore, you must wait for
the stone to cool off prior to retesting.
PRO-D 3 FEATURES
1. Helps to identify diamond and white
sapphire, including genuine sapphire
watch crystals. The test results are
shown via its PATENTED color-coded
light pipe and unique sounding beep
tones.
2. Quickly assists with testing most any
size diamond, whether mounted or
loose.
3. The sleek and ergonomic shape
comfortably rests in and on your
hand when held, and the tester has
PATENT PENDING intuitive finger grip
pads for increased user-friendliness
and ease of use.
4. The LED illuminator is positioned
under the probe tip. The LED
Illuminator is a super bright white
LED that illuminates the stone being
tested.
5. The tester is equipped with a
spring-loaded probe tip designed
to protect the probe tip if excessive
force is used while testing or if it is
accidentally dropped.

6. The tester housing is made from
durable ABS and is covered with
GemOro’s exclusive rubberized paint
that provides an even greater grip.
7. Powered by (3) supplied 1.5V AAA
NiMH rechargeable batteries and
conveniently charged by a micro-USB
adapter. The rechargeable batteries
may be substituted with AAA alkaline
batteries if a suitable power outlet
is unavailable to recharge the NiMH
batteries.
8. The tester is also designed to have its
batteries charged with the optional
GemOro UltraDock 3 charging station
accessory (Item #0772).
9. Includes a GemOro rubberized
protective carrying/storage case,
aluminum loose stone holder, as well
as (3) user-replaceable AAA NiMH
rechargeable batteries, a universal
multi-voltage 100V-240V AC adaptor/
charger cube with micro-USB cord.
10. The tester is also designed to be
used with the optional handy PATENT
PENDING GemOro Test Stone
Magnifier attachment, which when
clipped onto the tester’s tip area
allows the user to more easily see
and test small diamonds without
accidentally touching the setting or
prongs (Item # 0780).
11. The tester has an auto-off function
to preserve the battery life and it will
automatically turn itself off after a
period of 5 minutes of non-use. After
powering down, if you wish to resume
using the PRO-D 3, simply touch
the tester’s power button and within
seconds the tester will turn itself back
on again.

If you wish to replace the NiMH
batteries with alkaline batteries, after
removing the battery compartment
door as described above, insert (3)
high-quality AAA 1.5V alkaline batteries
into the battery compartment. The
proper polarity positioning is indicated
on the side of the battery compartment
wall showing the direction of positive
(+) and negative (-) polarity so that it
is correctly positioned in the battery
holder. Carefully replace the battery
compartment door.
2. The PRO-D 3 batteries may be charged
by placing it in the optional UltraDock
3 battery charging station with the
micro-USB power cord plugged into
the rear of the charging station or by
plugging its supplied micro-USB power
cord into the rear of the tester and the
USB adapter cube directly into a wall
outlet. Once the tester is connected to
the AC adapter or the charging station,
the tester will switch to its DC power
mode. The tester’s built-in Intelligent
Charging Circuit ICC will automatically
identify the type of batteries installed
(NiMH rechargeable batteries
or alkaline batteries). If alkaline
batteries are installed, the circuit will
automatically cut off the power supply
to the batteries so that the alkaline
batteries will not be recharged. If NiMH
rechargeable batteries are installed, the
