Royal Weddings: Tiaras - the Congo Diamond Tiara

Every royal bride needs a tiara and even when they don't have one to call their own they can usually rely on a soon to be regal relative to find something they can borrow for their big day. That's exactly what happened to Maria Teresa de Mestre when she married the then Hereditary Grand Duke of Luxembourg in 1981 and walked into the Cathedral of Notre Dame wearing a tiara lent to her by the woman about to become her mother-in-law. It wasn't just a dash of sparkle, it was a family tradition in the making for the Congo Diamond Tiara worn by the royal bride that day had been used by her husband's mother for her own marriage almost thirty years earlier.

The Congo Diamond Tiara belonged originally to Princess Josephine Charlotte of Belgium and it was first seen when she married Jean of Luxembourg on April 9th 1953. The diamonds were said to possibly have been a gift from the bride's father, Leopold III, who had abdicated his throne two years earlier.

There are rows of round cut diamonds in this creation with a line of baguette cut stones between them. It is a slim and subtle tiara and was worn by both Josephine Charlotte and Maria Teresa towards the middle of their heads with thin veils attached behind it.

The tiara was also used by Josephine-Charlotte's two daughters for their weddings. Princess Marie-Astrid wore it less than a year after Maria Teresa when she married Archduke Carl Christian of Austria in Luxembourg on February 6th 1982.  Just five weeks later, the tiara was worn by Marie-Astrid's sister, Princess Margaretha, when she wed Prince Nikolaus of Liechtenstein on March 20th 1982.

The wedding tradition of this tiara seems to have ended there as the next generation of Luxembourg royals haven't used it.  So its most famous outing in modern times remains the moment that Maria Teresa wore it for her Valentine's Day Wedding in 1981.
