This holiday season, one lucky consumer will be taking home a very special diamond necklace. Christies is auctioning off Creation One, a necklace that features a 163-carat diamond that could fetch up to $35 million. It's being called the largest D Flawless white diamond ever put up for auction. Reportedly the size of a matchbox, Creation One is also the largest diamond ever mined in the African nation of Angola. By the way, Creation One is equal in value to the combined average incomes of more than 8,000 people in Angola.
