Photo Credit: Jamie McCarthy/Getty Images Sisters Jessica and Ashlee Simpson have always been close, but who knew they shared the same taste in jewelry? When Diana Ross" son Evan proposed to Ashlee a few days ago, he gave her a stunning Neil Lane diamond and ruby engagement ring (below). People reported that the 5-carat ring is set in platinum and gold and has 140 white diamonds.

The central ruby is more than 5 carats and the diamonds bracketing it are more than 5 carats, according to People. And Lane might need to craft another ring soon for the Simpson girls: Jessica is planning to walk down the aisle soon. "We need to get married," said the singer-actress-fashion mogul, who has a daughter, Maxwell, 20 months, and a son, Ace, 6 months. I already feel like we're like an old married couple already.
