A set of three lapel pins awarded to employees in recognition of long service with AECL. The two rectangular pins, which feature semi-precious stones in their setting, were part of a series awarded every five years, starting with 20 years of service. At 30 years of service they featured a single small diamond; at 35 years the pin featured two diamonds and then, at 35 years of service, three diamonds. The pins measured 10 mm by 13 mm and were introduced around 1990. The third pin, awarded on retirement, was for 32 years of service. It was awarded to Roger Jarvis on his retirement in 1989.
