Platinum and its brothers: the challenge of certified metals by Legor Group SPA

Can the challenge of environmental sustainability also be declined and won with metals?

Legor Group SPA, a global reference point in the metallurgical and chemical sector at the service of the goldsmith-silver and fashion accessory industries, has demonstrated this in the field and shown the way.

To date, in fact, it is the first and only company in the sector able to certify that its alloys, powders and galvanic solutions are made with precious metals that come 100% from recycled sources and are included in the Chain of Custody. According to the specialized portal Circular Economy Europe, the use of recycled metals instead of finished virgin minerals helps to reduce air pollution by 80%, water pollution by 76% and water consumption by 40%. 


Legor launches the "Magic 5": Gold, Silver, Platinum, Palladium and Rhodium, the five metals sustainable and certified, expression of an ethical choice rooted in Legor's DNA, in line with the production requirements of the circular economy and the increasingly important demands of future consumers. Each of these metals, in fact, has the Provenance Claim and Chain of Custody certification, official documents issued by the international Responsible Jewellery Council that attest to their integrity and complete traceability from procurement to the sales network. 


Here is the first Superhero: the Platinum


Periodically we will address each of the Magic 5 to understand its secrets, virtues and practical applications. Let's start with Platinum or "Pt" on the periodic table. Platinum alloys are attracting a lot of interest in the market because they are considered a viable alternative to the more expensive white gold. With the price of rhodium and palladium skyrocketing, companies have to face the market in a creative way to meet their own needs, combining them with those of their customers. The use of platinum by Legor Group SPA has resulted in the realization of a whole line of dedicated products and in the development of a series of pre-mixed formulations, which, unlike traditional alloys and ready-to-use alloys, contain a part of platinum that allows a good mixing of elements with a high melting point or anyway immiscible (such as ruthenium or iridium).

In addition, the company's research and development laboratories have created PTLUX, a new galvanic process that allows the electrodeposition of platinum in an alloy with a small percentage of ruthenium. PTLUX was born with the aim of obtaining a precious finish, even whiter than pure platinum, at a lower cost than rhodium and less subject to market fluctuations. Through this process, a whiter color than pure platinum is achieved, an additional savings as well as proven ease of use and good performance as an intermediate layer before final coloring.
