Originally designed and built by Roy Gaerth in Adelaide in 1972, these heavy duty lapidary grinders have long been the machine of choice for many people in the Australian Opal Industry, and in Gem and Lapidary Clubs right around Australia. Roy eventually sold the manufacturing rights to Gemmasta Lapidary Equipment in Flinders Park, South Australia and it was later aquired by Shell-Lap in Adelaide. In 2018 Shell-Lap closed when the owner retired and the manufacturing moved to Ballina in NSW.

Since then the machine has undergone several design improvements to make it even better than the original.

The Gemmasta GMP8-3 now comes with a full stainless steel tray that replaces the galvinised steel tray that was previously supplied with this model. The bearings have been replaced with fully sealed units.

The 3/4 Inch shaft has been updated to a full 1 inch stainess steel shaft. This provides additional rigidity and greater support, particularly those users that want to run heavy sintered grinding wheels.

The 1 inch shaft also means that lapidary wheels used on this machine do not reqire bushing and are less prone to vibration.

This is a machine that is built to last, made of solid cast aluminium components with a lifetime warranty against manufacturing faults.
