Welsh singer Dame Shirley Bassey is auctioning off some of her most treasured jewelry, including a diamond ring gifted to her by Sir Elton John. The proceeds from the auction will benefit Bassey’s chosen charities. Some of the highlights include a diamond necklace estimated to fetch between €270,000 and €320,000, a diamond and gold parure created by Cartier estimated between $215,000 and $269,000, and a 1960s vintage Van Cleef & Arpels ring covered in white diamonds that Elton John gave her after she sang at one of his AIDS Gala evenings.
