| PRESIDIUM
GEM TESTER/COLOUR STONE |
 |
| The design
of the Presidium Gem Tester is based upon the use of heat
conductivity to distinguish |
| diamond stimulants
from diamonds. It incorporates a sophisticated thermoelectric
probe and a |
| thermometer
which ensures reliable readings. The Presidium Gem Tester
can be used on mounted or |
| unmounted stones,
which can be as small as 0.02 carat. Includes an AC adapter,
a soft vinyl pouch, and |
| a hard plastic
case. |
