When Countess Stephanie de Lannoy weds Prince Guillaume on Saturday royal watchers will be eager to see which tiara she chooses to top her golden locks.
The Belgian-born future royal certainly has an impressive array to choose from, many of which are Luxembourg royal family heirlooms.
But following the tragic passing of her mother in August, there is speculation that the 28-year-old bride will choose pay tribute to Countess Alix de Lannoy through her choice of jewellery.
Stephanie is already wearing her mother's engagement ring alongside her own, but revealed that her relationship with her mother-in-law, Grand Duchess Maria Teresa, is very good.
"I consider myself very lucky", the Countess said, "since my mother died, the Grand Duchess has been very present in my life, and she has been a sort of second mother here in Luxembourg."
Due to this strong bond, as well as her impending royal status, Stephanie may choose to wear a tiara from Maria Teresa's collection.
Belgian Tiara with Diamond Spiral
This piece was a wedding gift from the Belgian National Bank to Maria Teresa's mother-in-law - Princess Josephine-Charlotte of Luxembourg - which she wore during her wedding to Grand Duke Jean in 1953.
The tiara is adorned with intricate diamond spirals that surround a fabulous, classic diamond centerpiece.
Tiara of the Congo
Princess Josephine-Charlotte received another tiara as a wedding gift, this time from the former Belgian colony of the Congo. She also showcased it on her wedding day and 30 years later Maria Teresa wore it on hers when she married Grand Duke Henri.
A total of 161 stones on a platinum base make up this tiara created by Parisian jeweller Van Cleef & Arpels and the headband features two rows of brilliant-cut diamonds coupled with a row of baguette cut diamonds.
Tiara of the Dukes of Nassau
Prince Guillaume's great-grandmother wore this tiara for her wedding to Felix of Bourbon, Prince of Parma in 1919.
The spectacular diamond piece was donated by the Duke and Duchess of Nassau and it previously belonged to the treasury of the Grand Duchess of Russia.
Diamond floral Tiara
Due to its highly popular design, this tiara is often worn by Grand Duchess Maria Teresa, seen here at the 70th birthday celebrations of Carl XVI Gustaf of Sweden.
Many European royal houses have their own, similar floral tiaras, including both the Spanish and Danish Royal Families.
The Spanish tiara was a wedding present from the government to Queen Sofia whilst the Danish piece was given to Queen Margrethe by her parents, Frederik and Ingrid.
Pearl and diamond tiara
Manufactured by French Jeweller Chaumet, this tiara has a diamond lattice base surmounted by beaded peaks. The base of the tiara can also be worn as a choker necklace.
Aquamarine Bandeau Tiara
This deco-style tiara is composed of aquamarines interspersed with large diamonds. Originally made for Grand Duchess Josephine-Charlotte, it is now often worn by her daughter-in-law Maria Teresa.
Nassau Sapphire Tiara
This stunning tiara is adorned with elegant leaves and berries that surround a large round cut sapphire, which can be removed and used separately.
Created around 1865, the tiara was originally the posession of Grand Duchess Adelaide of Luxembourg and belongs to Nassau's "Hause-Schmuck" or collection of family jewels.
Like Grand Duchess Charlotte, who often wore this tiara in official portraits, Maria Teresa also has a particular fondness for the piece, having worn it during such events as the state visit to Sweden in 2008.
