161. Diamond Tiara
Worn By: Princess Anne of Denmark
Owned Since: Unknown
Estimated Value: $10,000-$500,000*
This Tiara, though stunning, is actually of unknown provenance. The central diamond cluster in this headpiece is no doubt worth tens of thousands, and Princess Anne of Denmark wore it for her wedding. Though its accompanying necklace was a gift from Queen Elizabeth and King George VI, the Tiara is likely a Swedish or Danish heirloom.

It’s possible that this Tiara originated from Princess Ingeborg of Sweden, the grandmother to Prince George. Ingeborg gifted tiaras to Princess Anne’s sister-in-law for her 1949 wedding, so perhaps she did the same for Princess Anne when it came time for her to get married.
162. Queen Mary’s Diamond Stomacher
Worn By: Queen Mary
Owned Since: Late 1800s
Estimated Value: $500,000-$1 million*
A stomacher, for those who don’t know, is also called a devant de corsage. This jewelry is worn on the center panel of a dress, hanging down to the wearer’s midsection. Queen Mary owned a very opulent diamond stomacher that was made of diamonds set in white gold and gold. The stomacher consisted of three brooches in differing sizes, made from pear-shaped and brilliant pendants.

Queen Mary gifted the stomacher to Queen Elizabeth II, who redesigned it, turning it into a brooch that she could wear on her sash. As a jewelry piece, stomachers have been around since the late fifteenth century, when dressmakers began creating triangular-shaped panels for women’s gowns’ bodices.

Queen Elizabeth has worn the Welsh Guards Leek Brooch on quite a few occasions, particularly when she has gone on military visits. The Brooch was presented to Queen Elizabeth II as a gift from the 1st Battalion Welsh Guards. This Regimental Gift cost each soldier around 12c and a half pence.

From the 1970s until now, you can always spot the Queen wearing this Leek brooch when doing anything relating to the Welsh Guards. Leeks are important to Welsh history. The symbol originated from a battle with the Saxons, when St. David told the Welsh soldiers to put leeks in their hats in order to distinguish what side they were on.

Worn By: Queen Alexandra
Owned Since: Early 1900s
Estimated Value: $5,000-$10,000*
The Ladies of North Wales Leek Brooch has been worn by a few Royal family members, including the Duchess of Cornwall.

Queen Alexandra was the Prince of Wales’ bride, and she was also a fashion icon in her own right. In the nineteenth century, women rushed to copy her looks. For example, Alexandra often wore chokers to hide a scar on her neck. That is why chokers became a huge fashion statement during the late 1800s and early 1900s.
166. Irish Guards Brooch
Worn By: The Queen Mother
Owned Since: 2000
Estimated Value: $1,000-$5,000*
When Kate Middleton wore a shamrock brooch in 2022, people fawned over it. Little did they know, this brooch has a two-decade history dating back to the Queen Mother. The Irish Guards Brooch was created in the Queen Mother’s honor in 2000, when the famed Royal celebrated her hundredth-birthday.

The Queen Mother always presented shamrocks to the Irish Guards on St. Patrick’s Day, and, to celebrate her becoming a centenarian, they gifted her a shamrock-shaped gold brooch. In Irish culture, shamrocks are a symbol of St. Patrick’s Day because the missionary used these clovers to explain Christianity’s Holy Trinity.
167. Grace Kelly’s Engagement Ring
Worn By: Princess Grace of Monaco
Owned Since: 1956
Estimated Value: $38.8 million*
Adjusted for inflation, Grace Kelly’s engagement ring is now worth nearly $40 million, making it one of the most expensive engagement rings of all time. When Prince Rainier III proposed in the mid-1956s, the ring was priced at over $4 million. It was super-expensive then, and it has only risen in value over the years, even though the Hollywood-starlet-turned-princess has passed on.

The Cartier-made diamond ring is now in the possession of the House of Grimaldi, who keeps the 10.48-carat ring under lock and key. The emerald-cut diamond has gone down in history as one of the most iconic Royal engagement rings of all time.

Maharaja Duleep Singh of Lahore was the last Maharaja of the Indian Empire and, like the rulers before him, he had lavish taste in jewelry. In this photo, he is wearing a diamond sarpech.

This turban accessory has three plumes, all of which are made of diamonds. There is an emerald in the center. In Hindu literature, the emerald represents Mercury, a small-yet-mighty planet that holds a strong influence over someone’s life.
169. Gold and Amethyst Bracelet
Worn By: Queen Victoria
Owned Since: 1839
Estimated Value: $3,000*
Queen Victoria was famous for being very enamored with her husband. The Royal Family has not always been known for marrying out of love, but Queen Victoria and Prince Albert were soulmates. The two married in 1840, and they had nine kids together. When Queen Victoria announced that she and Prince Albert were engaged, she received a lot of lavish gifts.

One such gift was this gold and amethyst bracelet, which the Duchess of Kent gave her in late November of 1839. The bracelet was made of solid gold and featured two stunning purple amethyst hearts, no doubt to symbolize Albert and Victoria’s love for one another.
170. Three-Strand Van Cleef & Arpels Suite
Worn By: Princess Grace of Monaco
Owned Since: 1956
Estimated Value: $500,000-$1 million*
Unlike a lot of European dynasties, Monaco doesn’t really have a conventional collection of jewelry handed down from generation to generation. Princess Grace Kelly had to start her own from scratch when she wed Prince Rainier in 1956. One set that she used to start her collection was a gift from Van Cleef & Arpels, a French jeweler.

The jeweler gifted her a pearl and diamond parure, but Van Cleef sent a sample to Prince Rainier first. Rainier loved the jewels so much that he bought an entire set from the jeweler’s boutique in New York. The set included a cultured pearl necklace, earrings, and a small bracelet, in addition to the parure.
