Jean Ghika, head of jewellery UK and Europe at Bonhams, says: “This necklace provides us with a unique insight into the levels of opulence and display at the 1911 Delhi Durbar and it is extremely rare to have such a magnificent jewel survive intact. The necklace is not only fascinating historically but is also in superb condition. This is a singular opportunity to purchase a beautifully made historic jewel, the quality and lavishness of which we rarely see in jewellery nowadays.”
