She looks more like a champagne gravel to me. Definitely not a cinnamon gravel, unless she's got other genes floating around.
Did they have any info on her parents at all?
As a heads up, if she is champagne gravel, she could have a bit of a wobble when she gets stressed out. Usually the worst of it is they get confused on which way is up.
You could always consider having her shed skin tested once more tests are available. I can't remember if they proved cinny and Blk pastel to be the same gene. They do have a test for gravel right now iirc.
