Throughout human history, gemstones have always played an important role. Whether used as jewelry, crafts or decorations, gemstones are a shining part of human civilization. To transform raw gemstones into gorgeous works of art requires exquisite processing techniques. In this article, we explore how gemstones are worked, revealing this ancient and mysterious art and skill.
1. Preparation
The first step in working with gemstones is preparation. This includes selecting suitable gemstone raw materials, cleaning and inspecting the gemstones to ensure that their texture and shape meet processing requirements. At the same time, you also need to prepare the corresponding tools and equipment, such as grinding discs, saw blades, grinders, etc.
2. Cutting and sawing
Cutting is one of the key steps in gemstone processing. Cut the raw stone into the desired shape and size by using a saw blade or other cutting tool. During this process, special attention needs to be paid to maintaining the integrity and beauty of the gemstone and ensuring the accuracy and finesse of the cutting.
3. Lapping and Grinding
Polishing and grinding are important steps in processing gemstones, which can make the surface of the gemstone smooth and shiny, and highlight its color and inner beauty. At this stage, it is necessary to use various grinding discs and abrasives with different particle sizes, select according to the hardness and texture of the gemstone, and gradually carry out coarse grinding, medium grinding and fine grinding until the desired effect is achieved.
How to choose gemstone grinding disc?
Gemstone grinding discs are usually divided into two main types: resin grinding discs and sintered grinding discs. Resin grinding discs are cheaper, suitable for general processing tasks, and have good self-sharpening properties. Sintered grinding discs are more durable and suitable for tasks requiring higher processing pressures and temperatures, but are generally more expensive.
Comparison of the pros and cons of different grinding discs
| Characteristics | resin diamond grinding disc | Sintered grinding discs |
| Life | short | long |
| Shape Retention | a little good | very good |
| Self-sharpening | very good | a little good |
| Cutting force | weak | strong |
| Processing objects | diamond and gemstone | glass |

4. Polishing and retouching
Polishing and retouching are the final steps in gemstone processing, making the surface of the gemstone smoother and more refined, and enhancing its color and luster. In this process, special polishing tools and polishes are used to achieve the best gloss and transparency on the surface of the gemstone through repeated polishing and polishing.
Processing gemstones is an ancient and mysterious art and skill. It combines science, technology and creativity, and demonstrates human pursuit and exploration of beauty.Moresuperhard hopes that we can provide consumables to make your gem processing more efficient like diamond cutting wheel,diamond grinding disc and diamond polishing paste.

In modern manufacturing, tungsten steel (hard alloy) is widely used due to its high hardness and wear resistance. However, the requirements for tools when processing tungsten steel are extremely high, especially the selection of suitable grinding wheels is crucial in the grinding process. This article will share the case of us providing customers with high-quality grinding wheels and successfully solving their processing problems.
SG grinding wheels are suitable for grinding carburized steel. Their high hardness and self-sharpening properties enable them to effectively grind the high hardness surface of carburized steel, while low heat generation and good heat dissipation reduce thermal damage during the grinding process. In addition, the wear resistance of SG grinding wheels also helps to extend the service life of the grinding wheels and reduce grinding costs.
