By Erika Winters

Rare and exceptional diamonds have made big news in the last couple weeks, as the autumn jewelry auction season is in full swing, and large diamond finds continue to grab attention. Notable stories include a 118-carat (egg-sized) diamond that broke auction records at Sotheby’s Hong Kong by selling for a whopping $30 million. And Mouawad’s L’Incomparable diamond necklace (aka the world’s most valuable necklace according to Guinness World Records) is available for sale in Singapore for a cool $55 million. A brooch with a 96.62-carat yellow diamond, created by Van Cleef & Arpels in 1971, will head to Sotheby’s Geneva for its Magnificent Jewels sale on November 13.

The past few weeks have also brought news of some significant diamond finds. A 257-carat diamond was recovered at Lucara’s Karowe mine in Botswana, while a rare 12-carat blue diamond was recovered at Gem Diamonds’ Letseng mine in Lesotho.
