"  The Duchess of Cambridge&amp;#039;s engagement ring has been revalued at \u00A3300,000 ($506,550)\u2014that&amp;#039;s more than 10 times the amount it was worth in 1981. The inherited ring, which features a 12-carat sapphire surrounded by 14 diamonds, was valued at \u00A328,000 ($47,278) when it was given to Princess Diana by Prince Charles. The revaluation was part of a study conducted by jewellery expert Vashi Dominguez, who compiled a list of the world&amp;#039;s top 20 most famous engagement rings, noting how much each had risen in value since purchase. While Kate&amp;#039;s ring unsurprisingly topped the list, it was followed by that of the Queen (a three-carat diamond solitaire surrounded by five smaller diamonds), worth \u00A3100,000 ($168,850). Also to make the list were Michelle Obama&amp;#039;s (valued at \u00A326,000, or $43,901), and the Duchess of Cornwall&amp;#039;s (worth \u00A3250,000, or $422,125).
