In 1939, following a trend initiated by Sheaffer with his White dot and followed by other brands, also Parker adopted a symbol to indicate the lifetime warranty, putting in the head of their pens clips the Blue diamond, a small diamond in blue enamel. Unlike what happened for other brands the symbol was introduced late and for a relatively short period, going to disappear after a few years.
