OPERATING PROCEDURE
& OWNERS MANUAL
Congratulations on your purchase
of the TESTEROSSA by GemOro
Superior Instruments, the most
trusted name in gemological
instrumentation for the jewelry
industry. You’ve made a smart
choice, because the TESTEROSSA
is considered to be the world’s
best, most accurate, and durable
option amongst diamond testing
instruments designed to assist you
in separating true diamonds from
moissanite, white sapphire, CZ, and
other known diamond simulants.
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
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
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 Testerossa 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.

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 TESTEROSSA, 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 another
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 with the
GemOro Stone Testing Cloth or a
dry and clean microfiber or cotton
cloth or paper towel, 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 TESTEROSSA’s probe tip touches
these stones the metal alert feature or
moissanite indication may be set off.
The TESTEROSSA from GemOro
Superior Instruments 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 TESTEROSSA is an advanced,
technologically based instrument and
it should be used as a helpful tool
only. The TESTEROSSA 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
TESTEROSSA 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
TESTEROSSA is a helpful screening
instrument that by design is to
be used as a quick method for
helping to identify diamond,
moissanite, and white sapphire. The
TESTEROSSA 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

GEMORO TESTEROSSA 6 7
with the use of the TESTEROSSA. No
warranties exist with respect to the
TESTEROSSA 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 TESTEROSSA
or its use, the maximum liability of
GemOro, and its affiliates, dealers,
and distributors shall be the amount
paid for the TESTEROSSA.
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
TESTEROSSA 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 TESTEROSSA 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 TESTEROSSA and for
convenience it should be used to
wipe any hand or body oil from
the stones surface prior to testing.

GEMORO TESTEROSSA 8 9
via its PATENTED color-coded
light pipe and simultaneously
it is also spoken verbally in one
of nine different PATENTED
user-programmable languages
(English, Spanish, German, Italian,
French, Japanese, Mandarin
Chinese, Russian, and Arabic).
Instead of talking, alternatively
the tester may be programmed
to provide unique PATENTED
ring tones when identifying the
various materials or other alerts.
2. Quickly assists with testing
most any size diamond and
moissanite, including the new
most difficult to identify, super-
low electrically conductivity
Forever One moissanite,
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 handling.
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 virtually indestructible
polycarbonate, and has a
molded rubber base for
increased impact resistance.
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,
body 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
lay it on a table, counter or other
flat surface. Place the tester at a
90-degree angle against the paper
with the probe tip lightly touching
it. Apply enough pressure to gently
depress the retractable probe tip
slightly inside the housing while
carefully rubbing the probe tip
on the paper in a forward motion
a few times to clean it. 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 TESTEROSSA’s 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 for
a few seconds prior to retesting.

2. The TESTEROSSA’s NiMH
rechargeable batteries may be
charged by placing the tester in
its included UltraDock 3 battery
charging station with the micro-
USB power cord plugged into the
rear of the charging station or by
plugging its micro-USB power
cord into the rear 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 batteries will be recharged and
at the same time the tester may
be used with the AC adapter.
3. To turn the TESTEROSSA ON, press
the oval shaped power button
located on the top center edge of
the tester I and hold it down for
approximately one second, then
release the button. The power
button’s blue LED indicator will
begin flashing. The warm-up time
is approximately 25 seconds.
When it has fully warmed up, the
flashing blue LED light will become
solid. At this time the tester will
say, “READY” or if in the ring tone
setting, a bell will chime twice. You
may now begin using the tester.
4. To turn the TESTEROSSA OFF,
press the oval shaped power button
once again I and hold it down for
approximately one second, then
release the button. The power
button’s blue LED indicator will no
longer be illuminated indicating
it has been turned OFF. If the

minutes without being used, it
will automatically turn itself OFF
and say, “POWER DOWN”.
5. When using the TESTEROSSA
for the first time, the factory
setting is designed to indicate by
default to the English-speaking
mode. While in this mode it
has the ability to identify and
say “READY,” “DIAMOND,”
“MOISSANITE,” “METAL ALERT,”
and “POWER DOWN”. To change
the indication, while the tester is
powered on and the blue power
switch is illuminated, press and
hold the power button down until
the indicator begins scrolling
through the various options. The
options include: English, Ring
Tone, Spanish, German, Italian,
French, Japanese, Mandarin
Chinese, Russian, and Arabic. Once
the desired indication has been
found, remove your finger from
the button. The TESTEROSSA’s
indicator will remain in that mode
the next time the unit is powered
up or until it is physically changed.
6. The TESTEROSSA is also equipped
with a PATENTED color-coded light
pipe and probe tip cone indicator.
This line of sight colored indicator
allows the user to easily see the
test results while keeping their
eyes on the stone being tested.
GREEN = Diamond
BLUE = Moissanite
PINK = Sapphire
RED = Metal Alert
7. Prior to using the TESTEROSSA,
be certain to REMOVE THE WHITE
PROBE TIP CAP J at the front end
of the tester that serves to protect
the probe tip from accidentally
being bent or broken. The cap
may be easily removed by simply
applying a minimal amount of
pressure to the top and bottom
sides of the cap, as you hold it
between your thumb and forefinger.
Then gently pull it down, out and
off. Always replace the cap when
the TESTEROSSA is not in use.
8. To properly hold the TESTEROSSA,
it is important to grasp the tester
similarly to how you’d hold a pen,
but with your thumb and forefinger
touching the PATENTED finger
pads located on either side of
the tester K. This will allow you
to easily manipulate the tester
PROBE TIP CAP
J
POWER BUTTON
I

and make the best contact with
the stone being tested. While
holding the tester, its ergonomic
shape allows it to comfortably rest
in and on the top of your hand.
If you hold the tester without
touching the finger pads, the metal
alert feature will not function.
9. The LED Illuminator allows the
user to easily see the stone being
tested to confirm that only 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.
10. 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 TESTEROSSA.
NEVER TEST A RING WHILE
PLACED IN A RING BOX OR IT
MAY NOT TEST CORRECTLY.
Position the stone’s table M in
front of the testers probe tip.
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 depressing
the retractable 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.

11. Testing Loose Stones: Place
the loose stone in the supplied
aluminum loose stone testing plate
positioned with the stones culet
pointing 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
TESTEROSSA in your other hand,
firmly touch the probe tip to the
loose stone’s table until the test
result it indicated N. YOU MUST
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.
12. The probe tip must be cleaned
routinely to ensure proper contact
with the stone being tested. To
clean the tip, take a piece of
uncoated white printer or copy
paper and lay it on a table or
counter or other flat surface.
Place the tester in a 90-degree
angle against the paper with
the probe tip lightly touching it.
Apply enough pressure to gently
depress the retractable probe tip
slightly inside the housing while
carefully rubbing the probe tip
on the paper in a forward motion
a few times to clean it. Repeat
this process routinely or prior to
testing each time to ensure the
cleanliness of the probe tip.
13. Using the 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 counter. 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. When the charging station
is plugged in and has power, the
diamond shaped indicator on the
front end of the dock will remain
glowing green. You may now
simply place the TESTEROSSA in
the charging stations cradle with
its bottom edge facing down, and
the rear of the TESTEROSSA facing
the back end of the cradle. When
placed in the cradle, always confirm
the tester is properly seated in
the UltraDock 3 and is charging,
as indicated by the round LED
indicator on the TESTEROSSA next
to the testers power button glowing
either yellow for charging batteries
or green for fully charged batteries.
The TESTEROSSA will automatically
have its NiMH batteries charged
while in the UltraDock 3 O.

14. Using the Test Stone Magnifier:
This accessory will allow you to
see a magnified view of the stone
being tested and help ensure that
you’re making proper contact with
the probe tip and stone while not
accidentally touching the setting
or prongs. After removing the
testers probe tip cap, take the Test
Stone Magnifier’s wider side of its
oval shaped frame and insert it
over the TESTEROSSA’s probe tip
cone in the direction of the arrows
inside of the frame and clip it into
place. Depending on whether you
are right or left handed, you may
conveniently position it on either
side of the tester. Pivot the hinged
magnifier so that it is positioned
in front of the testers probe tip.
You may now view the stones you
are testing under magnification
P. To remove the Test Stone
Magnifier, carefully grasp it
near the oval shaped frame
for leverage and with a slight
twisting motion it will expand
the opening on the frame so you
may then gently pull it off Q.
MAINTENANCE:
1. The TESTEROSSA is not user
serviceable other than battery
replacement, probe tip cleaning,
and recalibration. If service is
required, please contact your
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
damage to the TESTEROSSA may
occur if there is battery leakage
and it will void the warranty.
4. In the event the TESTEROSSA
is not used for an extended
period of time, the batteries
should be removed.
5. Routinely clean the probe tip.
6. The TESTEROSSA is not user
serviceable other than battery
replacement, probe tip cleaning,
and recalibration. If service is
required, please contact your
supplier or the factory. Any other
attempt to repair the tester by
a user will void the warranty.
HELPFUL SUGGESTIONS:
1. Prior to testing a stone, always
make certain the stone being
tested has been cleaned and has
no hand or body oil on its surface,
while noting that this oil may not
be visible to the naked eye. Since
the TESTEROSSA is a highly
sensitive instrument that is capable
of identifying even the lowest
electrically conductive moissanite,
and because hand and body oil
are electrically conductive, without
first cleaning the stone you may
get a false-positive moissanite
indication when testing a diamond.
2. If substituting alkaline batteries
for the NiMH rechargeable
batteries, only use high-quality
AAA alkaline batteries.
3. The TESTEROSSA 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.
4. The TESTEROSSA has been
calibrated at the factory and
should not require further
calibration. If after using the
TESTEROSSA it is determined that
recalibration is required, please
contact the factory for calibration
instructions, which can be easily
accomplished by any user.
