The secret of accuracy of the Gem Master II is found not only in its high quality components, electronic circuitry and
craftsmanship, but also in its unparalleled
"standard" features. These features are designed to make the Gem Master II
the easiest and most accurate faceting machine available, while slashing the amount of time
required. First and foremost is
the ELECTRONIC MICRO STOP (EMS) METER, THE HEART OF THE GEM MASTER II.

HERE IS HOW THE EMS CAN IMPROVE YOUR ACCURACY AND SAVE YOU TIME:
As the first facet in a series is cut to the desired angle and depth, the needle moves up the
meter scale. When the facet is completed and the grinding stops, the position of the needle on the meter is noted. As each subsequent facet in a series is cut, an audible tone denotes
the identical needle position on the meter. Upon hearing this tone, you know to move on to the next facet. When using this method, upon completion not only are all your facets
identical but your time involved is cut dramatically! If the use of the tone is not desired, a switch is provided to turn it off and allow only the meter needle to operate
Example: After the first facet in a series is cut (taking a minimum of time)
the remaining facets in the series can be cut in six to ten seconds each!
