The Company

DIAMOND the fiber meeting


The history of Diamond, which is a traditional Swiss company, began in 1958, with the machining of ultra-hard materials and manufacture of industrial jewels, record player styluses, and other high-precision components. The experience gained in these endeavours formed the basis of the company's expertise in precision machining and volume production, expertise which has been systematically expanded and perfected over the years.

Since the dawn of mankind, nature has provided models to help explain complex phenomena and relationships. Observation of the principles of nature, and the pursuit of their underlying causes, forms the basis for discovery and innovation. Sometimes, those innovations are even more fascinating than what nature itself has created. Optical fiber technology provides a good example. By taking advantage of the properties of glass, it has become possible to efficiently transport unprecendented amounts of information through hair-thin fibers. Information which has helped make our lives simpler, safer and more enjoyable.
