Marie-Chantal's tiaras

Since her marriage to Pavlos, we've seen MC in a total of 4 tiaras:

Antique Corsage Tiara

L-R: MC, Ingrid and Anne-Marie

This pearl-and-diamond floral tiara first belonged to Queen Victoria of Sweden in the form of a set of brooches. Queen Ingrid of Denmark, Victoria's granddaughter, later inherited the brooches and had them set into a tiara for her daughter, Princess Anne-Marie of Denmark, now Queen Anne-Marie of Greece, on her 18th birthday. Marie-Chantal wore the Antique Corsage on her wedding day, and then to many events some time later in her marriage. We now see this tiara most frequently on Princess Theodora; it's the only tiara she's ever worn. Tatiana Blatnik, now Princess Tatiana of Greece and Denmark, also wore the tiara on her wedding day in 2010.

Art Deco Floral Tiara

The Art Deco Floral tiara was created by British jewelers William & Son for Marie-Chantal to wear to the wedding of Crown Prince Frederik of Denmark and Mary Donaldson. The tiara consists of 56.28-carat diamonds set in 18-carat gold. It costs an estimated £750,000.

Queen Sophia’s Diamond Tiara

L-R: MC, Sophia, Helen and Frederica

This all-diamond knockout was given to Queen Sophia of Prussia from her mother Empress Frederick of Prussia (Princess Victoria, Queen Victoria of the UK's daughter) as a wedding gift. The tiara was handed down to Sophia's daughter Princess Helen (Queen Helen of Romania) after her (Sophia's) death. It was then given to Sophia's daughter-in-law, Princess Frederica of Hanover, who, on her wedding day, became the Queen of Greece. Frederica was pictured frequently wearing the tiara and has let her daughter-in-law Anne-Marie wear it a few times, as it was her (Frederica's) favorite piece.

Since Frederica's death in 1981, Queen Sophia's tiara went unworn and unseen for over 40 years. In 2012, at Queen Margrethe of Denmark's 40th Ruby Jubilee dinner, Marie-Chantal shocked us all when she whipped out this bad boy for one night.

Marie-Chantal's Fringe Tiara

Of the previous three tiaras I've talked about, this one is the only one MC owns personally. It's been said that Robert Miller, MC's father, bought the tiara for her, and I've also heard that Chantal Miller, MC's mother, purchased the tiara for her as a wedding gift and is intended for Marie-Chantal's only daughter Maria-Olympia.
