Available for over a year

Consisting of two kilograms of gold and 444 gemstones, the iconic St Edward’s Crown will play a central role in the coronation of King Charles III, as it has for many of his predecessors. There has been much speculation as to what the value of the centrepiece of the Crown Jewels really is. Charlotte McDonald talks to Dr Anna Kaye, historian and author of The Crown Jewels: The Official History, and Alan Hart, CEO of the Gemmological Association of Great Britain. Together they break down what we know about how much it cost to make the crown in the 17th Century, and what it might be worth today.
