You may also attach the optional
GemOro Test Stone Magnifier to the
Pro-D 3 by clipping it onto the end of
the tester’s probe tip cone. This will
allow you to see a magnified view of
the stone being tested and help ensure
proper contact with the stone while
not accidentally touching the setting
or prongs.
8. Testing Mounted Stones: With one
hand, hold the ring (or setting) that
contains the stone you wish to test and
in your other hand hold the PRO-D 3
(see image). 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 spring-loaded 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.
