Meghan Markle wore her very first tiara on her wedding to Prince Harry last May 2018. It was a nondescript diamond bateau loaned by Queen Elizabeth, which she inherited from her grandmother Queen Mary.

However, before Duchess Meghan marched down the aisle, reports stated that she had a row with the royal staff over her choice of tiara because she wanted an emerald crown. Now, the real reason why the queen didn't allow her to wear a Vladimir Kokoshnik crown, which had seven large emerald stones, might have finally been revealed.

The tiara controversy has hounded Duchess Meghan and Prince Harry after The Sun reported that Queen Elizabeth rejected her request to wear the emerald tiara. Allegedly, the Queen had to put her foot down when the Duke and Duchess of Sussex had a heated exchange with the staff who told them their request was not possible. 

But, the denial may have nothing to do with whether the Queen likes or dislikes Duchess Meghan. According to Daily Express, the tiara choice all boils down to tradition as royal brides have never worn complicated tiaras with colored jewels. 

Instead, royal brides wore diamond-encrusted tiaras on their wedding day. Queen Elizabeth, Princess Diana, Sarah Ferguson, Sophie Rhys-Jones, and even Kate Middleton wore diamond crowns when they got married, as did Queen Elizabeth's sister, Princess Margaret. 

The lone royal to wear a tiara with colored jewels on her wedding day was Princess Eugenie, who wore a Greville Emerald Kokoshnik with a large gemstone, to her wedding to Jack Brooksbank in October 2018. The choice was a nod to her mother's Irish heritage

A royal source also said that there were concerns over the emerald tiara Duchess Meghan originally wanted to wear because of its dramatic history. It used to be owned by Russia's Duchess Marie of Mecklenburg-Schwerin, the daughter-in-law of Alexander II of the Romanov family.

Duchess Marie's son snuck the tiara out of Russia during the revolution and was later sold to Queen Mary. Later, Queen Mary gave this to her brother, who then gave the emerald crown to his mistress. Queen Mary bought back the emerald crown for a steep price and has now become a family heirloom.  

Meanwhile, royal fans wonder what tiara will Princess Beatrice likely wear on her wedding in 2020. The queen's granddaughter confirmed her engagement with Edoardo Mapelli Mozzi last September.
