If you are delving into the magical world of jewelry and want to continue accumulating knowledge on the key topics of this fascinating sector, we have previously shared some of its most intriguing secrets; for example, how white gold is made or where diamonds come from.
But, have you ever wondered about the meaning of hallmarks on gold jewelry? Whether you have recently purchased a piece and want to understand the meaning of these identifying gold marks, or you are trying to determine the legitimacy of a piece before buying it, we want to help you understand the importance of these practical details.
For this reason, today we will tell you how to recognize jewelry hallmarks with the help of Mumit's expert jewelers. The sophisticated pieces you can find in their online jewelry store are a perfect example of 18-karat gold jewelry that always includes the relevant hallmarks to certify the purity of the gold and the originality of their designs. We invite you to discover the meaning behind these intriguing symbols.
The Brand Mark: A Guarantee of Quality and Originality
One of the most important gold marks that we must locate on any piece of jewelry is the manufacturer's hallmark. Whether it's their initials or the complete logo, as is the case with Mumit, it is a crucial way to detect that the design in question is an original piece and not a copy.
We recommend that you consult the appearance and style of the brand's hallmark that interests you and learn to recognize it to differentiate it from possible imitations. Those responsible for applying this engraving on gold use punches specially designed for the brand to ensure that it is truly inimitable.
To help you visualize it, we suggest you observe the engraving on the inside of Mumit's Cross Diamond Ring in 18 Kt Yellow Gold, where you can appreciate the minimalist and elegant character of its distinctive logo. This iconic ring with a strong romantic and timeless personality is also available in white gold and rose gold. We advise you to review the appearance of the hallmark in each of them to learn to recognize it regardless of the possible variations it may present depending on the color of the metal.
We show you another perfect example of a fine jewelry hallmark on Mumit's Nina Ruby and Diamond Choker in 18 Kt Rose Gold. This time, you'll find it on the small link that adorns the clasp of the choker. One of the main advantages of choosing jewelry with the Mumit hallmark is that you can be sure that its quality will meet the brand's high production standards. Thus, the hallmark guarantees that beyond the sublime quality of the 18-karat gold, the exquisite diamonds and rubies that adorn this necklace have also been carefully chosen for their high purity and beauty to meet Mumit's selective criteria.

Why is the laboratory assay mark important?
In Spain, the assay mark from specialized jewelry laboratories serves as a certificate of authenticity and quality. Laboratories, officially accredited to carry out the relevant quality tests, use punches to mark the metal in a specific way that will be recognizable by expert eyes.
Regarding the information provided by this mark, you will usually see a number indicating the purity of the metal. For example, all Mumit jewelry features a 750, indicating that 75% of its composition is pure gold. This is the criterion corresponding to 18-karat gold and in Spain it must be indicated by law. Therefore, if you come across a piece of jewelry without a hallmark, you will not be able to know if it is authentic gold.
Where to find hallmarks
After having explained in detail what jewelry marks consist of, we want to tell you where you can find them. As we have learned, it is important to locate them even if they are very subtle or the piece in question is small, as they serve as a guarantee of authenticity and quality.
Most commonly, whatever the piece of jewelry, they will appear in a discreet place such as the inside of a ring or the back of an earring. In the case of bracelets and necklaces, you will often find them on some type of link near the clasp, or on the inside in the case of a rigid bracelet. If you cannot see it clearly, you can always use a magnifying glass or take it to an expert.
Mumit's Mabi Blet Classic Pearl Bracelet in 18 Kt Yellow Gold is a perfect example of marks that appear subtly but clearly engraved on a decorative plate attached to the clasp. Fully integrated into the elegant design of this exclusive bracelet, it fulfills an aesthetic function in addition to guaranteeing its originality.
In summary, we hope to have clarified that jewelry marks are not mere adornments but authentic quality certificates. By having learned the meaning of these engravings, we are sure that it will be easier for you to make an informed decision when purchasing gold jewelry.
