The design of manually operated work benches and working methods in the diamond polishing industry has not changed for hundreds of years. Occupational health studies of diamond polishers have identified high rates of musculoskeletal disorders of the hands and arms, specifically, ulnar neuropathy at the elbow. These are due to the high musculoskeletal demands placed on the upper body in the practice of this manually intensive profession. A study conducted at the Technion Israel Institute of Technology addressed itself to the investigation of the ergonomic aspects and occupational diseases relating to safety issues among craftsmen in the diamond polishing industry. The tasks in this industry, with its high demands for manipulative movements, include movements that require frequent, rapid hand exertions. An epidemiological review conducted during the years 1989-1992 in the Israeli diamond industry has pointed out that the manipulative movements experienced in diamond polishing very often cause serious health problems to the worker in the upper extremities and in the upper and lower back. When such occupational hazards affect workers, it produces a chain reaction that eventually affects the industry’s economy as well. For thousands of years, diamonds have been objects of fascination, beauty, richness and capital value. Skillful craftsmen and artists have tried, through the ages, to create beauty by enhancing the shape and values of this unique form of hard carbon crystal formation. In contrast to the continuing achievements of artistic creation with the native stone and the emergence of a great international industry, very little has been done to improve some questionable...
