READ BEFORE USING
A high percentage of the
new generation, super-low
electrically conductive Forever
One or “F1” moissanite that
was introduced in late 2015
will incorrectly be identified
as diamond when tested on a
traditional combination electrical
and thermal conductivity tester.
However, your UltraTester 3+
uses the new patented UV-
F1 TECHNOLOGY™, and it is
exclusively calibrated to identify
this faint electrical conductivity
property. Please note that the
new Forever One moissanite
can no longer be easily visually
identified, as it is now D-E-F
“colorless”, with few inclusions.
Be aware that body oil is also
electrically conductive. Due to
the tester’s enhanced sensitivity
for electrical conductivity, dirty
diamonds may potentially test
as moissanite. To avoid false/
positive readings on dirty
diamonds, ALWAYS CLEAN
THE STONE by simply wiping
the body oil off on the provided
STONE TESTING CLOTH prior to
performing a test. Periodically,
also clean any accumulated body
oil off of the probe tip by gently
rubbing it on a piece of uncoated
paper - SEE MANUAL.

OPERATING PROCEDURE
& OWNERS MANUAL
Congratulations on your purchase
of the UltraTester 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 tester to date, the UltraTester
3+ offers even more. Separate true
diamonds from moissanite, 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 the thermal
(or heat) conductivity property of
a diamond is significantly greater

GEMORO ULTRATESTER 3+ 4 5
than all other gemstones (except
moissanite and synthetic diamond).
White sapphire is also thermally
conductive, yet not as conductive
as a diamond or moissanite.
The recognized, most practical way
for separating the vast majority of
moissanite gemstones from diamond
is the electrical conductivity test;
since most moissanite conducts
electricity, while diamonds, as well
as other known diamond simulants
do not. It should be noted that while
the vast majority of moissanite may
be electrically conductive, in some
moissanite gemstones there might
only be electrical conductivity in
a small varying degree. But have
no fear. With the new PATENTED
UV-F1 TECHNOLOGY™ built into
the UltraTester 3+, you can identify
the widest range of electrically
conductive moissanite material
available, including the new
super-low electrically conductive
Forever One moissanite.
Other than some rare and natural
colored diamonds, as well as some
lab grown synthetic diamonds,
natural white diamonds do not
conduct electricity. If a stone does
not conduct heat or electricity,
it will be determined to be more
than likely a common CZ or other
diamond simulant. Because hand-
oil is electrically conductive and
the stone being tested may not be
clean, any test result that indicates
moissanite, especially on smaller
size stones that haven’t been
cleaned, should be suspect, cleaned,
and retested. Due to the electrical
conductivity properties of some of
the chemicals commonly used in the
production of lab-grown synthetic
diamonds, when the UltraTester 3+’s
probe tip touches these stones the
metal alert feature or moissanite
indication may be set off.
The GemOro Superior Instruments
UltraTester 3+ utilizes both the
thermal conductivity and electrical
conductivity testing methods in one
seemingly simultaneous test, and it
will quickly help in identifying and
separating the stone in question.
The UltraTester 3+ is an advanced,
technologically based tool and it
should be used as a helpful device
only. The UltraTester 3+ is not meant
to replace the trained gemologist.
NATURAL COLORED DIAMONDS
& TREATED COLORED DIAMONDS
Because some fancy natural
colored diamonds and some fancy
treated colored diamonds are
electrically conductive, the GemOro
UltraTester 3+ should ideally be
used on colorless stones only. This
limitation applies to all testers
that utilize thermal and electrical
conductivity methods for testing
the authenticity of the stone.
IMPORTANT DISCLAIMER: The
UltraTester 3+ is a helpful screening
tool that by design is to be used as a
quick method for helping to identify
diamond, moissanite, and white
sapphire. The UltraTester 3+ should
not be used as the final method
for determining the authenticity

GEMORO ULTRATESTER 3+ 6 7
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 UltraTester 3+. No
warranties exist with respect to the
UltraTester 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 UltraTester 3+
or its use, the maximum liability of
GemOro, and its affiliates, dealers,
and distributors shall be the amount
paid for the UltraTester 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
UltraTester 3+ is plugged in. While
the batteries are being charged,
the tester may be used as desired
while powered by the AC current.
CONDITIONS FOR
IDEAL OPERATION
1. The UltraTester 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,
body 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. A
GemOro STONE TESTING CLOTH
(shown below) has been provided
with each UltraTester 3+ and for
convenience it should be used to
wipe any hand or body oil from
the stones surface prior to testing.

GEMORO ULTRATESTER 3+ 8 9
2. Quickly assists with testing
most any size diamond,
moissanite and white sapphire,
whether mounted or loose.
3. The sleek and ergonomic shape
comfortably rests in and on your
hand when held, and the tester
has PATENTED intuitive finger
grip pads for increased user-
friendliness and ease of use.
4. The LED illuminator and UV
fluorescence detector are
positioned under the probe tip.
The LED Illuminator is a super
bright LED that illuminates the
stone being tested and, since it is
a UV LED, it also helps to identify
fluorescence in diamonds.
5. The tester is equipped with a
retractable 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.
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 UltraTester 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.
ULTRATESTER 3+ FEATURES
1. Helps to identify diamond,
moissanite and white sapphire,
including genuine sapphire
watch crystals. The test results

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

6. Prior to using the UltraTester
3+, be certain to REMOVE THE
WHITE CAP at the front end of
the tester that serves to protect
the probe tip from accidentally
being bent or broken J. The
cap may be easily removed by
simply applying a minimal amount
of pressure to the sides of the
cap, as you hold it between
your thumb and forefinger.
Then gently pull it out and off.
Always replace the cap when
the UltraTester 3+ is not in use.
7. To properly hold the UltraTester
3+, it is important to grasp the
tester with your thumb and
forefinger while touching them
to the PATENTED finger pads
located on either side of the
tester K. This will allow you to
easily manipulate the tester and
make the best contact with the
stone being tested. While holding
the tester, its ergonomic shape
allows it to comfortably rest
on the top of your hand. If you
hold the tester without touching
the finger pads, the metal alert
feature will not function.

depressing the spring-loaded
probe tip all of the way in until
you hear a click sound, touch the
stone just long enough to allow
the tester to indicate a reading (1
or 2 seconds) and then take the
probe tip away from the stone.
Be aware that a stone that has
been overheated by prolonged
exposure to the probe, or from
body heat due to wearing or
the environment, may not test
accurately. Always allow the
stone and setting a few seconds
to cool off to room temperature
before testing. Blowing on the
stone will speed up this process.
10. Testing Loose Stones: Place
the loose stone in the supplied
aluminum loose stone testing
plate positioned with the culet
facing down into the recessed
hole part of the testing plate.
Then hold the testing plate
steady with one hand, as this
will also allow the electrical
current to pass through your
body, permitting the tester to
function as designed and test
properly. While holding the
UltraTester 3+ in your other hand,
firmly touch the probe tip to the
stone is being tested and that
the setting or prongs are not
accidentally being touched. This
LED is a special UV type L that
may also be used to identify
the fluorescence characteristic
found in approximately 30%
of all diamonds. You may also
attach the optional GemOro Test
Stone Magnifier (Item# 0780)
to the UltraTester 3+ by clipping
it onto the end of the tester’s
probe tip cone. This will allow
you to see a magnified view of
the stone being tested and help
ensure proper contact with the
stone while not accidentally
touching the setting or prongs.
9. Testing Mounted Stones: With
one hand, ALWAYS hold the
ring (or setting) that contains
the stone you wish to test and
in your other hand hold the
UltraTester 3+ M. NEVER TEST
A RING WHILE PLACED IN A
RING BOX OR IT MAY NOT TEST
CORRECTLY. Quickly, yet firmly
touch the testers probe tip to
the stone’s table, while being
certain not to allow the probe tip
to make contact with the metal
setting or prongs. While firmly

FOLLOW THIS PROCEDURE
WHEN TESTING LOOSE STONES
OR THE TESTER MAY NOT TEST
CORRECTLY. DO NOT ATTEMPT
TO TEST LOOSE STONES
WHILE HOLDING THEM IN
YOUR FINGERS OR THE TESTER
MAY NOT TEST CORRECTLY.
11. The probe tip must be cleaned
routinely to ensure proper
contact with the stone being
tested. To clean the probe tip,
take a piece of uncoated white
copy or printing paper and lay
it on a table or counter or other
flat surface. Place the tester
in a 90-degree angle to the
paper with the probe tip lightly
touching the paper. Apply enough
pressure to gently depress the
retractable probe tip slightly
inside the housing. Then carefully
rub the probe tip in one direction
on the paper to clean it.
12. Using the Optional UltraDock 3:
Place the charging station in a
convenient location near where
it will be used such as on a desk,
showcase or repair area. Take
the testers micro-USB power
cord and plug it into the rear of
the UltraDock 3, while plugging
the USB into its AC power cube
adapter. Plug the adapter into
a convenient wall outlet. You
may now simply place the
UltraTester 3+ in the charging
stations cradle with its on bottom
edge facing down, and the rear
of the UltraTester 3+ facing the
back end of the cradle. The
UltraTester 3+ will automatically
have its NiMH batteries charged
while in the UltraDock 3. O
13. Using the Optional Test Stone
Magnifier: Insert the UltraTester
3+’s probe tip cone through the
wider opening of the magnifiers
oval shaped bracket and clip
it into place. Depending on
whether you are right or left
handed, you may conveniently
position it on either side of the

supplier or the factory. Any other
attempt to repair the tester by
a user will void the warranty.
2. Always replace the protective
probe tip cap to keep the probe
tip from becoming damaged.
3. If using alkaline batteries, always
replace the batteries after long
periods of time to prevent
premature corrosion or battery
leakage, which is common with
old or spent alkaline batteries after
a period of time. Be aware that

HELPFUL SUGGESTIONS
1. If substituting alkaline batteries
for the NiMH rechargeable
batteries, only use high-quality
AAA alkaline batteries.
2. The UltraTester 3+ is designed to
be able to easily test faceted or
rough stones of virtually all sizes.
However, please keep in mind
that small stones will naturally
heat up much faster after being
touched by the probe tip. After
each test be certain to cool off
the stone by blowing on it or
waiting a few seconds until it cools
if a retest is required. If testing
diamonds in a pave setting, please
note it is easy to accidentally
overheat the stones next to the
one being tested. Therefore, it is
very important that you test the
stones while alternating testing
one area of the ring and then
another, while regularly blowing
on the stones to cool them off.
3. The UltraTester 3+ has been
calibrated at the factory and
should not require further
calibration. If after using the
UltraTester 3+ it is determined that
recalibration is required, please
contact the factory for calibration
instructions, which can be easily
accomplished by any user.
