Post pics of the inside and that will help.
I would just add that Celeste often has a powdery finish to the skin and a defined teardrop shape. Look at half of the pics at http://figs4fun.com/Thumbnail_Celeste.html and pay attention to "3-01 JN" and "4-23 GM" and "3-29 IS" which are the typical Celeste fig shape/size/interior/exterior, while noting that a couple of the figs in that page look like Black Mission or Vista to me...
Chain of nurseries: strike one.
Not the typical size and shape: strike two.
Not the typical coloring: strike three.
