In the photograph above, Princess Victoria of Hesse and by Rhine is wearing Queen Victoria’s emerald diadem.
Victoria (1863-1950) was the eldest daughter of Princess Alice of the United Kingdom, the second daughter of Queen Victoria. She married Prince Louis of Battenberg in 1884 and they had four children together.
After she and Prince Louis renounced their German titles, they became the Marquess and Marchioness of Milford-Haven.
One of Victoria’s daughters was Princess Alice (later Princess Andrew of Greece and Denmark), thus making her the maternal grandmother of Prince Philip. In this image, you can spot her at Prince Philip’s royal wedding. She is standing in the far right, holding a black handbag. The groom’s mother, Victoria’s daughter Princess Alice, is standing to the right of Queen Mary.
