A newly created set of drop earrings featuring a pair of large pear-shaped diamonds are expected to fetch $20-30 million when they go under the hammer next month, according to Christie's auctioneers.
The "flawless quality" diamonds weigh 52.55 and 50.47 carats. The set will form part of the Christie's "Magnificent Jewels" sale in Geneva on Nov. 15, alongside other sparkling earrings, necklaces and rings.
