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.
