What is Hallmarking?
The hallmark is an official sign or label on the precious metal pieces of jewelry, often to certify the compositions of noble, precious metals – for example, Platinum, gold, silver, and palladium in some countries. The word “hallmark” can also be used in a more general way to refer to any distinctive property.
Personalization was always a part of the evolution of jewelry making. An early stone age man would have invented and created the first wedding rings for his wife. Jewels are synonymous with intense emotion, whether purchased on a whim or for a specific occasion. Initially, jewelry was engraved by hand when there was no technology.
Computer-controlled (CNC) engraving machines, dot pins, and laser engraving machines for jewelry-making came into existence with advancements in technology. Don’t you feel the Gold jewelry you are buying for your beautiful wife or are loved once must be pure like your love for them?
For that, Hallmarking is a must. Where in the hallmarking center, the jewelry goes through a lot many processes and tests. In the end, the laser is hallmarked with which certifies that the jewelry we are wearing is pure.
Metal like gold and silver were started getting engraved and decorated with all modern engraving possibilities: text, photos, hand signature, fingerprint, brand logo, graphics, and many others.
The in-store trend is increasingly toward postponed personalization, allowing for the last-minute engraving of jewelry so that the customer can partake in the engraving as an event in the shop and create a memorable moment.
Jewelry is still in high demand online, as jewelers often showcase their creations with personalization options. Online engraving is famous because it allows customers to experiment with various fonts, images, and texts and preview the finished product.
The keys to engraving jewelry are aesthetic design and precision. Necklaces, pendants, or wristbands are easy to customize and are made exclusive. Supreme exclusively in gold needs hallmarking, which makes it more exclusive and genuine.
You can even engrave inside rings to make them much more personalized. Metal engravings on precious metals like gold, silver, or some other alloy are done for hallmarking, 3D/2D art creation to grab the customer’s attention.
Branding and hallmarking on Diamond are possible with laser marking without any loss (no chips, no dust). Laser marks on the surface vaporize only a very negligible amount of material. The tailored gem thus loses no valuable worth or weight.
What Are the Advantages of Micro-Laser jewelry Hallmarking laser machine?
- High sharpness
A Crisp & Clear thin line is the essential aspect of an exemplary laser Hallmarking machine. We have specially optimized our Laser gold hallmark machine for marking on Gold & Silver. Laser marking on Platinum is very crisp & precise. Even though it is a rigid metal, challenging to mark.
- Increased Power
Normally, fiber laser machines need two passes to etch gold. The first one to frost the gold and the second to engrave. It makes the laser marking less sharp. A very clean and precise mark is a must. It is most preferred for hallmarking Gold and Silver Jewelry. Hence, we optimize our laser for marking in one pass only.
- Improved Field of Focal Distance
This is an essential requirement of gold markings on jewelry, i.e., (Hallmarking Industry). Laser Hallmarking on curves is very tricky as focal point change can make the artwork smudgy on the edges. This aspect is very important on bangles and rings, especially when many rings are marked together, placed on a single jig.
- Special Effects
Laser Marking of micro-textures on gold jewelry is easy to make. Laser hallmarking marking of jewelry where it is challenging to create imitate logos and sign and character is easy. It must be the specialty of the hallmarking machine where Almost all Holographic effects are easy to generate.
What are some of the hallmarking techniques and hallmarking machine prices?
Dot pin Hallmarking machine Marking
Dot Pin Marking Machine is a commonly used method in jewelry makers for identifying a bar of gold as pure or (hallmarking) by the precious metal gold marking and engraving. It is widely used for marking, the dotted and the line marking forms of marking on the flat surface area and on the gold and silver.

- Price: 1500 to 4000 $
Hallmarking using punches
The hallmarks have always been “struck” with hardened steel punch dies. These punch dies are made with high HRC values of steel of different sizes. These punching machines and tools are of various sizes and are ideal for big silver jewelry.
The punches are rendered in a straight shank or shank, Later used to hallmark gold ring. The problem with the conventional punch dies is that the punch mechanism pushes metal, thus distorting the piece. The traditional punch was hand made which lag accuracy.
It implies that after hallmarking, the refinishing of the article is a must. Today the punch dies are made with CNC machining and laser engraving. These hallmarking dies are made with high precision. Price will be based on the puch dies and when the puch dies will deteriorate its quality we need to get a new one. so the price will be recurring. and would be costly in the long run.
Laser Marking System for Hallmarking
One of the best of best Hallmarking methods. Laser-marked jewelry is mostly the preferred method of Hallmarking on gold and silver jewelry. A modern laser-based marking technique is now possible and affordable.
It is particularly useful for fragile objects and hollowware that would be destroyed or warped by the punching technique. Laser marking systems thus eliminates the need for completed articles to be refinished.
Laser marking operates by evaporating substrate from the metal surface with high-powered lasers. There are two methods for laser marking: 2D and 3D. 2D laser marking burns the outline of the hallmarks into the object, whereas 3D laser marking more closely resembles punch marks. Price: 5000 to 8000 $ plus gold collection unit for 99 % recovery of gold.
What is the essential requirement to qualify as a Laser Hallmarking machine?
The Heatsign Fiber laser marking system is suitable for Hallmarkers who need to produce many items(Jewelry) per day. Hallmarking / Branding / Identifying (Traceability) laser markers have very small beam diameters, even less than 30 microns, but have very high peak power.
The laser must leave a hallmark on finely polished metal. As a result, the probability of the beam bouncing off is very high. To prevent destroying its resonator, the Hallmarking / Branding / Marking laser blocks the returned beam. It gives backlash protection against the Laser Beam. It helps in long-lasting laser lenses, mirrors, and optics.
A diode laser marker has a life expectancy of fewer than 10,000 hours, whereas a fiber laser marking system has a life expectancy of more than 100,000 hours, giving it an advantage over diode lasers. The same lifetime of the diode laser beam source would increase maintenance costs, adding operational expenses.
To etch gold/silver, conventional fiber lasers need two passes. The first will frost the gold/silver, and the second will engrave. It reduces the sharpness of the marking. For Hallmarking / Branding / Identifying(traceability) Gold and Silver Jewelry, a single clean mark is desired.
When purchasing a fiber laser for Hallmarking / Branding / Marking, keep in mind that it can perform the Hallmarking / Branding / Marking in one pass only, rather than two passes.
The Heatsign HALLMARK is an expert in precious metal branding and hallmarking. The numerous methods of making gold/silver make it the most versatile and therefore stand out from the competition.
Micropatterns on very glossy polished Gold or Silver jewelry should be done in such a way that such watermarks are impossible to reproduce, and therefore the items cannot be copied.
Heatsign is also researching to create more cost-effective and long-term strategic advantages in jewelry labeling and Hallmarking / Branding / Marking applications.
Despite the fact that the machine is very inexpensive, it still has the best capabilities as compared to other laser hallmarking machines/systems in the market.
