When it came time to propose to his longtime girlfriend, Kate Middleton, Prince William chose to do so with his mother Princess Diana’s engagement ring. The late Princess of Wales was presented with an oval 12-carat Ceylon sapphire ring that is surrounded by a cluster of 14 solitaire diamonds set in white gold by Prince Charles in 1981. Prince William surprised the world when he presented the same ring to his college sweetheart in 2010. The Duchess of Cambridge carries out her royal duties wearing the iconic ring, keeping her late mother-in-law's memory alive.

A modern piece fit for a modern Queen! While it’s rare to see Rania wearing a tiara, the monarch turns to her Boucheron Bracelet Tiara when the occasion calls for one. The simple, yet dazzling piece was designed by the French jewelry house Boucheron. Rania debuted the tiara, which features two rows of diamonds while incorporating Arabic script, back in 2008. The piece as the name suggests can be worn as a tiara or a bracelet.

The Queen Mother gifted Princess Diana with the large oval sapphire and diamond brooch for her wedding. As with most things she did in her life, the stylish royal put her own spin on the piece and converted it into a seven-strand pearl choker. Princes William and Harry’s mom often donned the large piece even after her divorce from Queen Elizabeth’s son.

The stunning tiara (pictured on Crown Princess Mary) originated during the court of Napoleon Bonaparte. In 1804 for the coronation of the French Emperor, Jean Baptiste Bernadotte purchased a set of ruby and diamond jewelry for his wife Désirée Clary. The couple would later become King Carl XIV Johan and Queen Desideria of Sweden. Over the course of history, the tiara was gifted to a Swedish Princess who became a Danish Queen. Since it was created, the tiara, which originally wasn’t even a tiara, has undergone alterations. The piece that began as individual floral arrangements was later assembled into a wreath tiara with brooches being added in 1947 by Queen Ingrid. The monarch left the tiara to her grandson Crown Prince Frederik whose wife Crown Princess Mary made her tiara debut in 2004 wearing the piece. Like Ingrid, Mary has had the headpiece altered. The complete Danish Ruby Parure now includes the tiara, hairpins, girandole earrings, a grand necklace, brooch, bracelet, and a ring.

King Felipe VI’s glamorous wife is known for making fashion statements when it comes to her engagements. The busy mom-of-two’s royal visit to London in 2017 was no exception. Letizia exuded glamour wearing what has been dubbed the Mellerio Floral Tiara during her trip. The diamond tiara, which is set in a floral motif, actually belongs to the royal’s mother-in-law Queen Sofia. Felipe’s mother was gifted the sparkler in honor of her marriage to Juan Carlos of Spain in 1962. Surprisingly, the tiara can be converted to a necklace — something Sofia did for her pre-wedding ball.

In February of 2017, the mom-of-three dug deep into the Dutch crown jewelry box and wore a diamond and ruby necklace that had not been seen in the public for nearly half a century. The piece is a part of a parure that was commissioned by Queen Wilhelmina of the Netherlands in 1897. The monarch requested Johann Eduard Schürmann & Co to make a diamond and ruby tiara using rubies that belonged to Queen Sophie. The tiara from the collection closely resembles the necklace Maxima wore that features a peacock tail.
