humanitarian: Princess Diana was the first British Royal who went into the field to bring awareness to tragedies caused by landmines. Something that was frowned upon by other senior royals and advisors.
This large oval sapphire surrounded by two rows of diamonds was a brooch given to Diana by the Queen Mother as a wedding present.

Diana wore it often and it soon became her signature piece of jewelry.
