Pippa Middleton and James Matthews dated briefly in 2012 and competed in various charity athletic and endurance races around the globe. James Matthews, $25 million London townhouse, is a hedge fund millionaire and owner of Eden Rock Capital Management. Middleton has been spotted wearing a stunning diamond ring. Possibly costing more than $260,000 it’s in white gold or platinum with a center stone at least three carats in size. “It’s a very timeless piece that will look as good now as it will in 50 years time. It’s bezel fit making it a bit more modern, which fits in very well with her style. If he has chosen that on his own then he has done brilliantly!” jeweler Annoushka Ducas described it. Pippa is a lifelong fitness fanatic who stays fit by following a low-carb diet and working out 3 to 5 days a week.
