It’s core theme will be modernisation and digital transformation of thinking and systems inside a global industry membership and certification body, and the positive impact that has on building international sustainable supply chains.  The content will be our authentic transformation story. We aim to provide inspiration and reassurance to the audience who may be going through change themselves.  We will include a mini case study on our certification process and that case study will include the role of technology and people in transforming the certification process to make...

Bulk Metallic glasses are a relatively novel class of materials. They exhibit hardness at least twice as high as conventional alloys, high elasticity, lower casting temperatures, minimal shrinkage on casting and thermoplastic formability. In short, more wear-resistant jewellery can be cast in near-net-shape or processed like plastics. Gold-, platinum- and palladium-based bulk metallic glasses are of significant interest for jewellery. However, several alloys undergo abnormally fast tarnishing, and the conditions for forming a metallic glass often conflict with hallmarking requirements....

The paper presents a new class of metallic platinum alloys with very different properties compared toconventional platinum alloys. Precious based bulk metallic glasses (BMG) are interesting materials forjewelry and watch making applications due to their special properties such as high as-cast hardness,good corrosion resistance, and outstanding surface quality. However, high critical cooling rates arerequired to achieve amorphous solidification, which implies challenges for their manufacturing. So farsuch alloys were only melted under laboratory condition and could not have been produced...

This paper will showcase the history and technique of mokume gane. From the beginnings in feudal Japan to it’s use as a jewelry material by modern smiths around the world, mokume gane is a demanding technique that even those well versed in jewelry metals struggle with. This presentation will illustrate the beginnings of mokume gane, and the techniques used daily by two of the most prolific makers of quality mokume gane in the world. Scientific method will be stressed, rather than scientific testing. This paper and  general jewelry skills will allow you to make...

There is a strong perception in our traditionally conservative industry that nothing much has changed over the years in terms of precious metal alloy compositions for jewellery application. A little reflection suggests that is not true. There has been change – significant change – and change continues to happen.  In this presentation, the changes in precious metal jewellery alloys that have occurred in recent times will be examined, notably in meeting the needs of the manufacturing processes in current use and improving the service performance of jewellery. It will highlight...

Binder Jet technology is quickly gathering interest in the world of precious and non-precious jewellery production although it is less known than Selective Laser Melting and other additive manufacturing techniques. Naturally, with every new and disruptive technology a list of doubts and questions arise about its viability and comparison with the known methods of production.   The presentation is focused on introducing Binder Jet technology in its applications for jewelry making and showing results from almost one year of use of 3D binder jet printers at our laboratories in...

Metal Jet technology represents a new approach to metal powder additive manufacturing of metal parts: well established and proven across several industrial sectors for production of stainless steel-based applications, Metal Jet is currently being introduced to the world of jewellery and fashion industry to unlock and open up new opportunities and manufacturing options. This presentation will deal with the concepts behind binder jetting, the enabling processes and unique applications of a Metal Jet printer. 

3D Printing in the jewellery industry, an in-depth review of the technologies past, the present and it’s possible future directions ABSTARCT This research and presentation is intended to act as a guide to inform all sectors of the jewellery industry, from educators to designers and from jewellery manufacturers of all types to the artisan hobbyist The paper will cover the development and use of of 3D Printing in the jewellery industry, it will also discuss in some detail the current ‘state of the art’ and finally take an in-depth look at the future. A future where we can expect to see...

L’intervento si focalizza sul rapporto tra la trasformazione digitale e il mondo del gioiello, e in particolare sulla dematerializzazione nel contesto contemporaneo dei prodotti, dei processi, dei servizi e delle esperienze. A partire dai cambiamenti e dagli effetti della trasformazione digitale ai molteplici contesti del gioiello contemporaneo vengono poi analizzate le tecnologie e gli strumenti digitali emergenti, le loro applicazioni a cavallo tra il mondo fisico e quello virtuale e la loro capacità di raggiungere le nuove generazioni. Infine, saranno illustrate le best practices...

Nel corso del 2022, oro e metalli preziosi hanno subito pressioni al ribasso alimentate da politiche monetarie restrittive e da un forte dollaro americano, tuttavia si sono registrati spunti positivi legati alla resilienza della domanda per lingotti, monete e al riaccumulo di riserve strategiche da parte delle banche centrali. Nel 2023, i prezzi dei metalli preziosi saranno ancora influenzati da dinamiche monetarie e valutarie, ma assumeranno una crescente rilevanza le condizioni economiche nei principali Paesi consumatori e gli equilibri geopolitici.    Il settore orafo...
