A massive 100-carat yellow diamond sold for a record-breaking $16.3 million at a Sotheby's auction in Geneva. One of most prized and rarest stones in the world, the Graff Vivid Yellow was sold to an undisclosed private buyer to a private vendor, reports Reuters.
Despite the record, the purchase fell short of Sotheby's expectations — it was expected to fetch upwards of $24 million. At least it looks great on a ring. -- Jordan Valinsky
