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!

“Creating artistic pieces isn’t easy, but it does become easier when you are using the right tools. This is why I focused on the Fac-Ette GemMaster when I began faceting in 2001. They are well-crafted and durable machines with a unique elegance about them. The fact that this machine allows me to work efficiently is a bonus.”

“As a professional gem cutter, I have had the privilege of working with different faceting machines. But one of the many benefits that the GM gives me is whether I’m working on a traditional SRB or experimenting with fancy shapes the GM can accommodate my needs effortlessly and precisely. The controls make it a breeze to switch between angles and indexes enhancing one of the most important things in this job, workflow, and productivity. Without the loss of precision. The machine’s robust components and precise engineering give it long-term reliability. Reducing maintenance and downtime requirements. This machine cannot fail you. Even if you try.”

“The GemMaster II is still the most accurate and easy-to-operate faceting machine I’ve ever owned. The heavy-duty construction and EMS meter system make it perfect for fast and accurate productivity. I’ve taught over 80 plus students to facet with the 13 faceting machines I own, by 8 different manufacturers. My GemMaster II is always the favorite for beginners and professionals alike.”
