The iconic tiara was worn publicly for the first time since the tragic demise of the People's Princess.
Celia McCorquodale, the daughter of Princess Diana's oldest sister, Lady Sarah, tied the wedding knot with George Woodhouse and she completed her stunning wedding look by donning her late aunt's stunning Spencer Tiara.
According to People, Diana won the same piece of jewelry when she walked down the aisle for her marriage with the Prince of Wales, Prince Charles in 1981.
Although Her Majesty Queen Elizabeth II wanted to loan Diana the Queen Mary Lover's Knot Tiara for the wedding, she passed it on and went with her family's topper for her special day.
The stunning piece of jewelry has always belonged to the Spencer family, whose aristocratic lineage dates back to the Tudor period.
The Spencer Tiara has enthralled the public with its beauty as it has been displayed through various museum exhibition over the years. However, it was publicly worn for the first time by McCorquodale since Diana's demise in 1997.
The history of the tiara goes back to Diana's grandmother, Lady Cynthia Hamilton. The online source informed that the central part of the tiara was given as a wedding present to Hamilton in 1919 during her marriage with Albert, Viscount Althorp, the future 7th Earl Spencer.
It was gifted to Hamilton by Albert's great aunt, Lady Sarah Isabella Spencer, who died later in that same year.
Furthermore, it was reported that the ends of the Spencer Tiara have come from a sparkler that belonged to Frances Manby, the last known Viscountess of Montagu.
The exact manner by which these pieces came in the possession of Lady Sarah is not known, but they got passed down to Cynthia and Albert from her.
The current design of the Spencer Tiara features diamonds shaped into tulips and stars surrounded by beautiful scrolls. The design was allegedly finalized sometime around the 30's.
