- Metals: Gold, silver, platinum, stainless steel, and titanium are laser-cut to create one-of-a-kind jewelry designs due to their malleability and durability.
- Non-metals: Traditional cutting methods for non-metals are time-consuming and require advanced skills. Laser-cutting machines ensure a convenient process when cutting and engraving crystals, gemstones, wood, leather, and acrylic materials.
Common Types of Laser Cutting Machines
The two main types of laser cutting machines are CO2 Lasers and Fiber Lasers, with each type designed to cut a specific type of material. While CO2 lasers are best for cutting and processing non-metals, fiber lasers are faster and suitable for hard-to-cut metals.
How Does Laser Cutting Work in Manufacturing Jewelry?
From making bespoke necklaces and bracelets to creating interlocking monogram patterns, laser cutting assures a cleat-cut outcome. Here’s a step-by-step process for laser cutting jewelry production:
Step 1: Design and CAD Creation
The first and most important step is to know what design and type of jewelry to create. Using CAD programs, such as AutoCAD and fusion360, you can create the jewelry design. Afterward, the design file is exported into a format that the laser cutting machine can recognize, such as DXF, AI, or PLT.

Step 2: Prepare and Position the Materials
The next step in laser cutting jewelry is selecting the materials based on design needs and preparing the materials by wiping and removing any dust or debris on their surface. Then, the materials are positioned for cutting according to the thickness and shape of the jewelry.
Step 3: Laser Cutting
At this stage, the design file is imported into the laser cutting machine. This is where the laser power, speed, and frequency parameters are adjusted. The laser cutting machine is started and it uses a high-energy laser beam to precisely control the cutting positions and shapes, moving along the set path to cut the material.
Step 4: Post-Processing
After cutting, the jewelry undergoes initial polishing to remove any burrs or uneven areas caused by the cutting process. Subsequent steps such as PVD coating or stone setting may be performed to enhance the appearance and durability of the jewelry. Some secondary pieces like hooks, strings, or chains can be added to jewelry pieces.
Advantages of Laser Cutting for Jewelry Manufacturing
Laser cutting systems are excellent for jewelry-cutting applications, as they can cut materials of varying thicknesses and ensure high repeatability and speed. Other advantages of jewelry laser cutting include:
Precision and Accuracy
Laser cutters offer a high-accuracy cutting solution for various types of jewelry materials, including metals and non-metals. Their focused laser beam allows for extremely precise cuts, making them suitable for simple and complex designs. As they are guided by computer systems, these machines conveniently make desired jewelry shapes and engravings.
