A few months ago Jennifer Aniston announced she was engaged to boyfriend Justin Theroux, but for some reason kept her engagement ring under wraps from the public to see, until now! Since the news was announce about the couples engagement, Jen has been wearing a simple gold band to mark the occasion, hiding the huge diamond she received off Theroux. But yesterday Jen was seen in New Mexico wearing the huge diamond engagement ring Justin proposed with on his 41st birthday. Aniston’s engagement ring features a huge eight carat emerald cut diamond held in a claw setting and mounted on thin platinum band. Many have said the size of Jens diamond ring looks more like a cocktail ring rather than an engagement ring worn every day. We expect, due to the emerald cut diamonds huge size the clarity grade is completely flawless as the cut of an emerald diamond shows more marks and inclusions than most of the other cuts. The couple got engaged this summer in New York where they were celebrating Justin’s 41st birthday, at the Blue Hill restaurant in Manhattan's Greenwich Village.
