Tips for using your SAM
The electrical conductivity of the new low electrical
conductivity moissanite may differ across various points
and vary from stone to stone. It is therefore advisable to
perform more tests on different points across the surface
of the suspected gemstones.
In the event of an alternating reading on the suspected
gemstone, it is recommended to refer the gemstone to a
reputed gemological laboratory for further analysis and
verification.
Do not use the tester without its battery cover during the
testing. Secure back the battery cover at all times for
safety measures.
The probe tip must be placed at a right angle or
perpendicular to the facet of the gemstone for an
accurate reading.
For proper operation of the tester, fingers must be placed
on the metal grip of the tester at all times.
To achieve optimum accuracy for tests involving very
small mounted gemstones (1.2 mm exposed diameter
and below), it is extremely important that no contact is
made on any mounted/ metal part of the jewelry piece.
The test results will likely result in confusion, as metal
is highly conductive and results may indicate that a
moissanite is detected instead.
To achieve optimum accuracy for tests involving very
small gemstones (10 points and below), it is important
to allow the gemstone to cool down before subsequent
tests.
