The GemMaster

Precision & Accuracy

The secret of the accuracy of the GemMaster is found not only in its high-quality stainless steel components, electronic circuitry, and craftsmanship but also in its unparalleled “standard” features. These features are designed to make the machine the easiest and most accurate faceting machine available while slashing the required time. First and foremost is the Electronic Micro Stop (EMS) Meter, the heart of the GemMaster.

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!
