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

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

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

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.
