GEO.2 Laser WeldingA unique technique developed by Tom Rucker
Inspired by Architecture and Aeronautics
light and strength
The idea of designing large scale jewellery pieces in a hollow and light but very strong structure was inspired by designs found in architecture or aeronautics, where large bodies with maximum strength and minimum weight is needed.
Tom was intrigued by the American designer, architect and visionary Richard Buckminster Fuller (1895 – 1983) and his giant Geodesic Dome. This was designed as a lightweight structure with maximum strength for the Montreal World Expo in 1967. In 1995, inspired by the Geodesic Dome, Tom introduced this technique to his work. Over the next two decades he worked to develop his intricate ‘GEO2’ laser-welding technique to its present exceptional, award-winning standard.

The technique – Microscopic detail, maximum impact
A very thin Platinum wire – just 0.2mm – is welded over a body which will represent the final shape, it has multiple laser welds at each joint. The whole structure and the laser joints are so fine that the entire work has to be manufactured under a microscope.
After the laser welding is finished, the body is dissolved to create a hollow structure. For some designs – rings for example – where extra strength is needed, the wire joins of both layers are connected to each other, adding more wire by laser welding.
4,500 single laser shots per square inch
The arrangement of the wire is not arbitrary: the pattern of each join follows a planned system. The angle of the joins, as well as the shape and size of each single segment, plays an important part in arriving at the strength required for a high quality piece of jewellery.
Once the welding process is completed some designs are submitted to various thermal hardening processes, enhancing the final strength of the product to the maximum achievable. Approximately 4,500 single laser shots per square inch and layers are needed to create a strong structure that can easily withstand normal daily usage.
