Our Cutting Process :

This is the process of semi precious stones, and mostly cut into cabochons and pendants,charms and beads. For precious stones with high value, which are brilliant cut and diamond cut, the cutting procedure will be different, it will be research carefully to get the highest yielding in size, shape and weight. Not mass cut into cubes.
2. Shaping : Before shaping, we have to order an abrasive grinding wheel with the target shape and size from the grinding wheel emery cutter supplier, we have to fix this wheel on our shaping machine first, then place the small cubes or slabs on the machine with the chucking fixture. Turn on the shaping machine, the grinding wheel will work automatically to grinding around the stone slabs, grinding away the spare parts, finally, the rough shape and size will come out after this step.
3. Grinding : After the shaping step, there are uncut areas from shaping, top and bottom, which are fixed by the fixture. So have to grind these parts away by hand. And you can judge and check the shape and size regularly to check if the best shape and size achieved.
After above steps, the basic shape and size is finished. Some items require further craft, such as carving, engraved, or drilling hole, and facet cutting. Some special stone materials might need heat treatment, filled treatment, and stabilized treatment.

Mix the finished stones into a big tumbler, or small tumbler, which is already mixed with abrasive material at a certain grid size. Till the final polishing and finishing achieve.
