Understandably, we have already mentioned that laser markings are permanent. Bug again, there are a few things you can do to get rid of the marks without interfering with the surface of the material.
To complete the process, you will have to laser the material around the area that has been marked. The idea is to blast it with the aim of removing the texture of the material. From there, you want to polish and smoothen the material.
While this process is easier with materials like stainless steel, platinum, and sterling silver, it is harder when you want to remove marks from the surfaces of gold and silver. The reason is that with gold and silver, the quality of the jewelry will vary from high to low quality as you move underneath the surface.
If you engrave these materials, the plating will be gotten rid of, which is why it is never very easy to remove laser marks from such materials. Even if you manage to remove the marks, once you are done, you must plate the items one more time to restore their original looks and quality.
