She claimed the Gem which was hidden here http://www.furaffinity.net/view/13765155/ She is the first one to ascend with a gem so far and you can see the gem on her chest now [of course that is not a claimable gem] If its on an ascended character odds are then it is the gem they used to ascend in the first place.

keep an eye out for more ascension gems and hints here http://www.furaffinity.net/journal/6548680/
