The story of the brooch goes back to when the Prussian Princess Louise Margaret in 1879 married the Prince Arthur, Duke of Connaught. One of the gift she received was the blue sapphire brooch. Princess Louise Margaret gave it to her daughter, Princess Margaret of Connaught and she brought it with her to Sweden when she married Prince Gustaf VI Adolf of Sweden.
Princess Margaret give birth to her only daughter Princess Ingrid of Sweden, future Queen of Denmark. When Ingrid is 10, years old (in 1920) her mother dies only 38 years old and she inherits the brooch after her.
# Princess Margaret's nickname was Daisy, like Queen Margrethe II of Denmark
According to The Court Jeweller, Queen Ingrid wore it at the engagement of her eldest daughter at that time Princess Margrethe II of Denmark in 1966.
At some point Queen Ingrid gave the brooch to her daughter Queen Margrethe II before her death which might be because she would like to see the next generation wear it. Unlike her mother she did not wear the brooch very often. One time was back in 1999 at the christening of Prince Joachim and Alexandra's oldest son, Prince Nikolai.
In 2006, on January 21, Crown Princess Mary wore it first time at her firstborn son, Prince Christian Valdemar Henri John's christening. Crown Princess Mary is the wife of Crown Princess Frederik of Denmark, the oldest son of Queen Margrethe II and Prince Henrik. Since then, she has worn the Connaught brooch multiple times at christenings, gala dinners, at new years eve etc. Queen Margarethe handed it over to Mary as a present. A long history in a small piece of jewellery.
In the middle of the brooch is a large blue sapphire. Around the blue sapphire are diamonds and two pendants of white pearl are hanging underneath the blue stone. Right under, a small pendant made of diamonds and a pearl is hanging. A beautiful piece of work.
