  1. We engrave the metal purity on every single item. So, ‘Pt 950’ is on every product, and Pt means Platinum; 950 represents 95% of the purity. This is to ensure and guarantee that every product adapts at least 95% of Platinum.
  2. Your customer ID is on the product as well to trace all steps of the production sections like which artisan is responsible for which actions. Since we cherish artisan-ship, we aim to deliver the best quality of product and best after-sales customer services as well.
  3. Our company’s hallmark is engraved on the product so to prove that it is from ByEnzo. More importantly, this is a vital hallmark to distinguish fake products.

To sum up, there are four parts to form the complete hallmark, including the fineness mark, customer ID, Brand name, and also the year of manufacture.

History of Hallmarking

It has a very long and rich history of hallmarking and it is originated from Europe, like France, the United Kingdom and Netherland, etc. According to The Goldsmiths’ Company in the United Kingdom, they have provided an extensive introduction about the system and here are some key points that you might find useful.

Since precious metals are rarely used in their purest form but are usually alloyed with other metals for workability, durability, wearability. So, it is not possible to detect an article’s precious metal content by sight or touch. As a result, it is a legal requirement for an Assay Office to hallmark articles containing precious metals if they are described as such in some countries.

The word luxury seems to be used so often these days.

But to be exact, luxury is a word that refers only to hand made. In the past, when aristocrats existed, the nobles used good things of high value so that their clothes or belongings could be distinguished from others.

The best materials and objects created by the best designers and artisans of their time are still displayed in the museum as treasures. It’s not something that’s seen in a mass-produced factory.

Men’s bracelets made by ByEnzo use the best metal, platinum PT 950, as the primary material. Moreover, a small portion of other metal alloys, which will change the strength and hardness of the material.
