The last of the Royal accounts were published today - the accounts of the Royal's charitable foundation, the immensely wealthy Royal Collection (RC) - and it makes for impressive reading, proving that indeed everything touched by Royal hands is turning to gold right now.
The most extraordinary detail is that the RC made £10million from entry tickets to view Kate Middleton's wedding dress which went on display for 73 days at Buckingham Palace last year.
No wonder that the trust's CEO Jonathan Marsdon is able to write in his foreword, "The marriage of The Duke and Duchess of Cambridge in April 2011 provided the best possible start to the year."
Kate’s dress, by Alexander McQueen designer Sarah Burton, was also the reason the palace attracted an “unprecedented” number of visitors to its annual summer opening.
A total of 626,678 people saw the dress, displayed alongside the diamond earrings given to her by her parents and the Cartier “Halo” tiara borrowed from the Queen, during the exhibition.
The figures show for the first time the “Kate effect” on the royal family’s finances. Overall, the Royal Collection’s income soared almost £8.5 million to £50.2 million in 2011/12.
The report says: "Retail activities enjoyed an extremely successful year, continuing to benefit from the effects of the celebrations surrounding the marriage of The Duke and Duchess of Cambridge. More than 190,000 items of wedding-related merchandise were sold during the year, at a value of almost £4 million...demand for products from this range was so great that a decision had to be taken to reduce wholesale activity and concentrate on selling through our own shops and online shop.
"The online shop has achieved a notable increase in sales following its redesign and relaunch, providing a strong platform for growth in off-site business in the future.
"The range of merchandise designed to commemorate the Diamond Jubilee of Her Majesty The Queen was launched on 10 October 2011, resulting in sales of 60,000 units by 31 March 2012. Limited-edition china has proved especially popular."
Sixty years and hardly a slip.
