A tiny portrait which Pablo Picasso set into a ring to appease his lover Dora Maar after an argument will go under the hammer at Sotheby’s London auction house next week. It is expected to fetch up to £500,000 ($630,000) when it is auctioned on June 21. The piece of jewellery was created by the great Spanish artist after he berated Maar for convincing him to trade an artwork for a ruby ring, prompting her to throw it into the River Seine.
