Why: Charity auctions are abound this month, and here's one we're especially fond of – both for the cause and the amazing prize. Through Feb.25, L'Oréal is auctioning off 2 diamond and platinum compacts on eBay to raise money for the Ovarian Cancer Research Fund. The compacts, designed by Kwiat Diamonds, are valued at approximately $4900 a piece. These breathtaking treasures embody timeless glamour and impeccable taste, and are being given away to the Oscar nominees for Best Actress this year. The auction ends on Monday, so head over to eBay to place your bids today.
