In 1939 (or 1940), 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, puttin 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.
