diamond
and moissanite testers with ultraviolet (uv) light
(set
jem-ii + jem-iii)
1)
diamond tester with uv light
2) moissanite tester with uv
light
one
of the greatest challenges gem dealers, buyers and gemologists
face today is being able to accurately determine the real
and authentic. the set contains a diamond selector and
a moissanite tester. it's a complete set of tool that
can identify the real and authentic diamond and eliminate
the moissanite. jem-ii, a diamond selector, can distinguish
a diamond from other stone simulants -like fake crystal
or simulants such as cubic zirconium - but not moissanite,
this is because moissanite has similar thermal conductivity
to that of diamond. after the stones has been tested and
filtered by a diamond selector a moissanite tester, jem-iii,
is needed to rule-out the moissanite from diamond is highly
suggested or recommended. doing so makes you 100% sure
that you're paying for the right stone. anyone, even without
training or previous experience in the jewelry and diamond
trade, can use this moissanite tester and easily receive
immediate & reliable identification of genuine diamonds.
stones as small as 2pt, rough or polished, unmounted or
mounted, can be tested under these devices in any type
of setting. read below to see the detailed information
of
1)
diamond selector with ultraviolet light (jem-ii):
this
diamond selector doesn't react on stones like fake crystals,
or simulants such as cubic zirconium, when the probe
touches the surface. it is the easiest answer for the
vast majority of retail jewelers, pawn brokers and chain
stores when faced with the decision of which diamond
selector to buy. why? because it works reliably and
share the most advanced diamond selector technology
on the market.
the
jem ii is a "touch and tell you" device that utilizes
the feature of high thermal conductivity of diamond.
it effectively and quickly distinguishes natural diamond
from all models of diamond simulants and metals, except
synthetic moissanite which has similar thermal conductivity
to diamond.
there
are some diamonds in the market these days which the
diamond selector detects even if the diamond is not
the genuine one. have a most reliable &
user friendly diamond selector, get the jem-ii diamond
selector!

operating information :
preparation
- insert
6f22 9v battery into tester. move the slide switch
to diamond and the power light will light up in red,
wait for about 25 seconds for testing probe to be
heated, the ready light will light up in green. at
this time, please make sure the led level meter first
bar is lighted if not, just adjust the level meter
volume to set the first bar lighted, then it's
ready for testing.
testing
- use
gem cloth to do normal cleaning work on stones to
be tested.
- for
mounted jewelry, please hold the jewelry
with one hand while the other hand is holding the
diamond selector keeping at least one finger touching
the electricity conductive panel of the diamond selector
then gently apply the testing probe to the stone to
be tested perpendicularly.
- for
loose stone, stone should be placed on
loose stone testing platform. hold the testing platform
on one hand while the other hand is holding the diamond
selector keeping at least one finger touching the
electricity conductive panel of the diamond selector
then gently apply the testing probe to the stone to
be tested perpendicularly.
- if
led lights up to red zone with three periodic beep
sound, then the stone that is being tested is a diamond.
if a simulant, all led bars do't light up
or it lights up to the green or yellow zone only (it
varies from different models of simulant). and a continuous
beeping sound will be heard if the probe touches the
metal part of the object to be tested such as rings
and earrings.
- recommended
testing environment temperature is from 18°c
to 30°c.
stone temperature should be the same as environment
temperature. environment temperature exceeding to
35°c
will cause incorrect testing results.
- replace
battery immediately as soon as red light dims.
- when
testing small stones (like 10pt below), it is recommended
to take off the diamond from body and let them cool
down to room temperature (from 18°c
to 30°c)
before conducting a test. small stones attached to
human body have higher temperature which causes incorrect
results when put on test.
- to
test the fluorescent reaction of stones under ultraviolet
light, move the slide switch to ultraviolet to light
up the ultraviolet led.
- ac
adaptor (110v-240v, dc 9v) is recommended (not included)
for long time indoor operation.
- always
set the slide switch to off position after every use.
- it
doesn't need to be calibrated when testing stones
with sizes over 5pt.
- adjust
the level meter volume to add lighted columns in led
level meter bars to meet special needs when testing
stones with sizes less than 5pt.
important reminders & maintenance:
- clean
your stone before testing - grease and other dirt
can give inaccurate test results
- hold
the probe of the tester upright, when touching the
surface of the stones
- once
the probe is warmed and the temperature is set or
fixed, the ready lamp automatically lights up
- always
slide switch to off after use
- a
new battery replacement is needed as soon as red light
dims or doesn't light up
- keep
the probe tip clean and always place the protective
cover over the probe when not in use to prevent inaccurate
results

2)
moissanite tester with ultraviolet light (jem-iii):
jem-iii
is a sure way to tell the difference between diamonds
and moissanite (man made diamonds). this tester will
leave you in no doubt as to the nature of your stones.
it is a "touch and tell you" device that utilizes the
moissanite feature, the different electrical conductivity
from diamond. it effectively and quickly distinguishes
moissanite from diamond. with the addition of the ultraviolet
(uv) light you can now test the flourescent reaction
of stones.
there
are some diamonds in the market these days which the
diamond selector detects even if the diamond is not
the genuine one. have the jem-iii moissanite
tester and be protected from the diamond simulant like
moissanite!

operating information :
preparation
- insert

to mois and the power lamp will light up in red. when
the ready lamp will light up in blue its ready for
use.
testing
- use
gem cloth to do normal cleaning work on stones to
be tested.
- make
sure to use a diamond selector to test all the stones
to be tested first, so that the fake stones other
than diamond or moissanite could be excluded first.
- for
mounted jewelry, please hold the jewelry
with one hand while the other hand is holding the
moissanite tester keeping at least one finger touching
the electricity conductive panel of the moissanite
tester then gently apply the testing probe to the
stone to be tested perpendicularly.
- for
loose stone, stone should be placed on
loose stone testing platform. hold the testing platform
on one hand while the other hand is holding the moissanite
tester keeping at least one finger touching the electricity
conductive panel of the moissanite tester then gently
apply the testing probe to the stone to be tested
perpendicularly. for large size stones, do the testing
on the top and bottom or front and back of the stone
to be tested to get a more accurate reading.
- if
all led bars in the indication window lights up with
continous beeping sound, the stone being tested is
a moissanite. the jem-iii will not give a beeping
sound if the stone that is being tested is a diamond.
and if the probe touches the metal part of object
being tested, the led bars in the indication window
might light up and continuous beeping sound might
also be heard.
- to
test the fluorescent reaction of stones under ultraviolet
light, move the slide switch to ultraviolet to light
up the ultraviolet led.
- always
set the slide switch to off position after every use.
