Hallmarking jewellery with a laser
Using a laser to put hallmarks on jewellery is a process which is becoming increasingly popular in the jewellery industry. It is a much more accurate and efficient method than traditional methods of hallmarking, such as stamping, engraving, or etching. This ensures that the hallmarks are precise and of a consistent quality across the entire piece of jewellery.
The laser hallmarking process first involves marking the jewellery with a thin layer of metal, usually gold or silver. This layer is then exposed to a high-powered laser beam, which is focused on the desired area. The laser beam melts the metal, creating a very precise and consistent shape. The hallmark is then etched into the metal, leaving a permanent mark on the jewellery.
This process is becoming increasingly popular due to its accuracy and efficiency. It is also much less labour intensive than traditional methods, which can be time consuming and require more skill. The laser hallmarking process is also much more cost effective than traditional methods, as it requires less material and labour.
Laser engraving personalisation
The marks made by laser engraving are permanent, legible, and abrasion resistant. These are essential qualities for jewellery pieces that are meant to last a lifetime and are sometimes even passed down generations. As lasers offer a non contact method of marking, the jewellery does not need to be clamped down on the engraving platform or to endure any physical impact. This reduces the chances of the precious jewellery suffering any secondary damage.
Laser engraving machines, using very fine but powerful beams of light, allow for the engraving of highly detailed and high resolution designs. Thus, fingerprint designs and multiple lines of text on wedding bands have been made possible by laser engraving technology. Even photos can be engraved on any piece of jewellery. The best part of printing highly detailed designs is that it is almost as simple as printing an image on a standard printer – all you have to do is load the design on the software, position the jewellery on the printing platform, and let the laser do its job.
