The Queen Mother had a cherished tradition of presenting shamrocks to the Irish Guards on St. Patrick's Day. To commemorate her 100th birthday, the Irish Guards gifted her a stunning gold brooch shaped like a shamrock, symbolizing her longstanding connection to the regiment.

In Irish culture, shamrocks hold special significance, as they were historically used by missionaries to illustrate the Christian concept of the Holy Trinity. This enduring symbol has become synonymous with St. Patrick's Day, representing Irish heritage and pride.
