The jewelry brand Eternha has chosen CRP Technology and its Windform GT, a composite material reinforced with fiberglass, commonly used to produce advanced and high-strength applications, to create some of the elements of the bracelets in its Men’s collection. This is an absolute novelty in the jewelry industry

The Eternha jewelry company was founded in 2020 by Stefano Massimiliano Marangoni and Chiara Cistriani. The shop was opened on June 25, 2022. Their creations combine traditional materials from the jewelery and crafts industry (natural gemstones and / or precious and non-precious metals) with hi-tech composite materials based on polyamide, used in some of the more advanced industrial sectors, such as Motorsports and Aerospace.

“It’s a brand new project, never done before,” said Chiara Cistriani. “50% of our investments are focused on product quality. The rest is innovation, eco-sustainability and the search for harmony between materials and colors. “

Hi-tech and fashion materials

It is a winning combination, completely reinvented in Eternha bracelets thanks to Windform composites.

Stefano Massimiliano Marangoni explained: “Our aim has always been to make high quality jewels. Once the level of materials was set, we wanted to be innovative; so we decided to include in our creations some elements made with a hi-tech material that, on the one hand, would give a precise identity to our bracelets, and on the other, allow anyone to wear something unusual for the fashion world. “

At this point there was nothing left to do but proceed with the creation of bracelets with hi-tech inserts. After some unproductive contacts, Chiara and Stefano met CRP Technology, “an international entity, with its historic headquarters in Italy,” added Stefano.

“After identifying the appropriate technology provider in CRP, we had to find the right material for our goals; we liked the idea of ​​combining our jewels with indestructible elements, made of a material used for extreme and functional applications, something “eternal”. Thanks to the collaboration with CRP Technology, we have discovered an extraordinary material, a polyamide-based composite, reinforced with glass fiber, developed and produced by CRP Technology: Windform GT ”.

Wind shape GT in the jewelery sector

Windform GT was used to produce, by selective laser sintering or SLS (a powder bed laser melting technology), some elements for the Eternha ‘Aquilha, Falcho, Lupho and Cobrha men’s bracelet models.

“They are small elements – Stefano specified – with a maximum length of about 10-12 mm. The shapes vary from parallelepiped to sphere and cylinder, with different graphic elaborations. And, in one case, with the engraving of our company logo “.

“Given the very small shapes – continued Chiara – we had to abandon some ideas and adapt others. But there are no compromises when it comes to quality. We wanted the top of the hi-tech range and we got it with Windform GT composite material ”.

Windform GT is a highly versatile composite material in terms of performance and aesthetics. In fact, it combines excellent characteristics of elasticity, ductility and impact resistance, with a deep glossy finish after hand polishing. It is also non-electrically conductive, resistant to moisture and liquid absorption, and is approved for skin contact.

Stefano added: “We wanted to include in our creations one or more elements made with a material used to create advanced and functional applications; a material capable of attracting customers for its intrinsic meaning and for the suggestions it evokes, more than for its excellent mechanical characteristics.

“We want to give ordinary people the opportunity to wear ‘a piece’ of technology, which will travel in space, race in motorsport competitions, improve the quality of life in the applications to come.”
