From the UK’s Queen Elizabeth II to Spain’s Queen Letizia to Margrethe II of Denmark, famous royals have long been known for their vast collection of valuable jewelry. But just how much would they need to pay to insure their tiara collections?

To find out, we created a list of eight countries around Europe with active royal families and identified their three most recently worn wedding tiaras. Each tiara was then valued by experts at , before we created an insurance estimate based on the age of the royal family member and the estimated cost of each tiara. 

We totalled these figures per country to identify how much each royal family could potentially spend protecting their tiara collection, before being ranked*. 

If you own expensive jewellery or high value items, it's important to find out if they are covered by your contents insurance. If you’re a homeowner and own the freehold, you might want to compare home insurance where your buildings and contents insurance are on a combined policy. Not only can it be the best home insurance, UK providers often offer cheaper premiums compared to having separate policies.

Which royal family’s tiara collection would cost the most to insure?

The United Kingdom (£297,466 per annum)

We can reveal that the country that would need to spend the most on insuring their tiara collection is the United Kingdom. According to Steven Stone, the total cost of the royal family’s three most recently worn wedding tiaras comes to £17 million, which means they could cost around £297,466 a year to insure.

1. Greville Emerald Kokoshnik Tiara

Valued at £10 million

Worn by Princess Eugenie of York when marrying Jack Brooksbank on 12 October 2018.

The Greville Emerald Kokoshnik tiara is made of rose-cut pave diamonds set in platinum and is adorned with six emeralds. The centre features a 93.7-carat cabochon-cut emerald. 

The distinctive diamond and emerald headpiece, made by the French jeweller Boucheron in 1919, is estimated to be worth £10 million – the most expensive of all the tiaras studied. Our analysis concludes that it could potentially cost the royal family £174,980 to insure annually.  

2. Queen Mary Fringe Tiara

Valued at £5 million

Worn by Princess Beatrice of York when marrying Edoardo Mapelli Mozzi on 17 July 2020.

The Queen Mary Fringe Tiara comprises 47 diamond bars with alternating smaller diamond spikes. It is set in gold and silver and was crafted in 1919 by the British jewellers Garrard and Co. using a diamond necklace that was given to Queen Mary on her wedding day in 1893. It is of particular importance to the British royal family as it is the same headpiece Queen Elizabeth II wore when she married the Duke of Edinburgh in 1947.

This tiara is estimated to be worth in the region of £5 million, which means it could cost the royal family £87,490 to insure each year.

3. Queen Mary's Diamond Bandeau Tiara

Valued at £2 million

Worn by Meghan Markle when marrying Prince Harry on 19 May 2018.

Queen Mary’s Diamond Bandeau Tiara is set with large and small diamonds in a geometric design. The centre stone on the headpiece is a detachable 10-diamond brooch, gifted to Queen Mary on her wedding day in 1893, making the tiara dual purpose.

The tiara was used for the first time in 65 years when worn by Meghan Markle on her big day in 2018. It is estimated to be worth in the region of £2 million, so we estimate the tiara could cost the British monarchy £34,996 annually to insure. 

The Netherlands (£266,769 per annum)

The Dutch royal family would need to spend the second most to insure their tiara collection. Steven Stone estimates the total value of the royal family’s three most recently worn wedding tiaras could add up to a figure in the region of £17 million. We estimate the tiaras could cost around £266,769 to insure each year.

Norway (£243,230 per annum) 

Norway’s three most recently worn royal wedding tiaras are estimated to be worth around £15.5 million, which is the third highest valuation of the eight countries studied. As a result, we estimate the three tiaras could cost around £243,230 to insure each year.
