Aniston was however pictured on Friday wearing a gold band on her wedding finger, which by the looks of it was turned around to hide the diamond and the style of the engagement ring.Jen and Justin confirmed the news of their engagement last week, after Justin popped the question at his 41st birthday party. Some insiders have said Jens engagement ring features a very large emerald cut diamond with tapered baguette sides. Emerald diamond engagement rings seem to be very popular amongst celebs at the moment, so it will be no surprise if her engagement ring is set with a large emerald cut diamond. But we will have to wait patiently for a photo of the ring.
