TESTER

GEMORO PRO-D 3 2

The new generation tester for diamond

fraud protection, the GemOro PRO-D 3,

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.

GEMORO PRO-D 3 6

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.

12. Glowing LED Light Pipe and Probe

Tip Indicator. Innovative PATENTED

colored LEDs visually indicate (see

images):

GREEN = Diamond

PINK = Sapphire

RED = Metal Alert

GEMORO PRO-D 3 10

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
