26. Princess Diana’s Emerald Cut Aquamarine Ring

Worn By: Meghan Markle
Owned Since: 1996
Estimated Value: $75,000*
Princess Diana certainly didn’t need to add to her sparkle, but a little bit of bling never hurt anyone – especially after a brutal split. After the Princess separated from Prince Charles in the mid-90s, she commissioned a jeweler to make a stunning emerald cut aquamarine ring.

Set in incredible, stunning yet dainty 24-carat yellow gold, the pale blue stone was seen on Diana’s finger several times. It most recently appeared on the hand of Meghan Markle, who wore it to the reception after she married Prince Harry in 2018. It’s thought the elegant piece is worth around $75,000 today.

27. The Burmese Ruby Engagement Ring

Worn By: Sarah Ferguson
Owned Since: 1986
Estimated Value: $78,000*
Rather than ask his mom for a loan of a family heirloom, Prince Andrew decided that his fiancee Sarah Ferguson deserved a specially made ring. Following in the footsteps of his brother Charles in breaking tradition, Andrew bought a spectacular Burmese ruby ring set with 10 diamonds on a thin yellow gold band.

When he popped the question back in 1986, Andrew paid around $33,000 for the sparkler. That equates to around $78,000 today, making this a very expensive piece of jewelry that Sarah was lucky to have – even if they did separate a decade later.

28. Marie Antoinette’s Necklace

Worn By: Marie Antoinette
Owned Since: 1700s
Estimated Value: $200,000-$300,000*
Marie Antoinette continues to be an interesting figure in history over 200 years after her untimely passing in 1793. The French queen and wife of Louis XVI was well known for her love of luxurious items, including her jewelry. However, what happened to the majority of it is relatively unknown.

Only a few pieces remain, including this pearl and diamond necklace that was auctioned off at Sotheby’s back in 2018. Featuring an incredible 331 natural pearls and a diamond clasp, this piece is the perfect embodiment of Marie Antoinette’s lifestyle prior to the French Revolution.

29. The Maple Leaf Brooch

Worn By: Queen Elizabeth II
Owned Since: 1939
Estimated Value: $75,000*
The Queen has been spotted wearing the Maple Leaf Brooch several times over the years. With its eye-catching diamonds and finely cut edges, it’s the perfect accompaniment to any outfit. The history of the brooch is just as rich as the diamonds it’s made from.

King George VI originally gifted the accessory to his wife Queen Elizabeth back in 1939 when they went to visit Canada. A decade later, Princess Elizabeth (who was still yet to become Queen) would wear it to The Great White North, too. The Queen Mother continued to own the piece up until she passed in 2002.

30. Diamond and South Sea Pearl Earrings

Worn By: Kate Middleton
Owned Since: 1990
Estimated Value: $100,000*
Princess Diana favored her diamond and pearl earrings as some of her most precious pieces. The People’s Princess wore them to several big events, starting with the Coronation Banquet of Emperor Akihito and Empress Michiko of Japan in 1990.

In the seven years leading up to her passing, Diana wore them many times, including on her last official engagement in 1997. Kate Middleton inherited them when she married Prince William, but hasn’t worn them quite as much. Kate did pair them with her white gown for the 2019 BAFTA’s, so at least they’re getting some use.

31. Cullinan III & IV Brooch

Worn By: Queen Elizabeth II
Owned Since: 1907
Estimated Value: $1.5 million*
The Cullinan III & IV Brooch is one of the Windsor family’s most expensive pieces, with an estimated value exceeding $1.5 million. Made from a huge 3,106 carat uncut diamond presented to King Edward VII in 1907, the brooch remains a truly precious part of the Royal Collection.

Queen Mary continued to wear the brooch until Queen Elizabeth II inherited her grandmother’s jewelry in the ‘50s. Understandably, Liz seldom wears the incredibly pricey jewel, but she did air it out for a state visit to the Netherlands in 1958, perhaps to keep up with the Dutch royal family.

32. Greville Emerald Kokoshnik Tiara

Worn By: Princess Eugenie
Owned Since: 1919
Estimated Value: $5-10 million*
Tiaras are to the royal family what cookies are to cream. You simply can’t have one without the other. The Greville Emerald Kokoshnik Tiara got special attention in 2018 when Princess Eugenie wore it on her wedding day. The perfect mix of diamonds and platinum creates the setting for the centerpiece – a huge 93.7 carat emerald.

The tiara was originally bequeathed to the Queen Mother from Dame Margaret Greville after it was originally designed in 1919. Amazingly, Queen Elizabeth II has never worn the stunning piece, but is happy to lend out the mutli-million-dollar tiara to her precious granddaughters.

33. Reflection Collection Diamond Cartier Earrings

Worn By: Meghan Markle
Owned Since: 2018
Estimated Value: $68,000*
Not every piece of jewelry worn by the women of the House of Windsor is a century old. In some cases, modern is just as pretty – and just as expensive. When Meghan got changed after her wedding ceremony in 2018, she opted to wear a pair of Cartier earrings.

The diamond and white gold set certainly weren’t cheap, even if they were new. Coming from the Reflection collection by the famous jeweler, they cost an incredible $68,000. They did match Meghan’s sleek white reception gown fairly well, so it’s not hard to see why she went for them.
