I don't think anyone can tell you if it's diffused or not via a photo.

It is difficult to provide an opinion on the photo of the stone you have posted. In regards to diffusion treated sapphires I have found this information from the GIA web site to be helpful in providing background information on this type of treatment for corundums:

http://www.gia.edu/cs/Satellite?blobcol=gfile&blobheader=application%2Fpdf&blobheadername1=Content-Disposition&blobheadername2=MDT-Type&blobheadername3=Content-Type&blobheadervalue1=attachment%3B+filename%3DThe-Identification-of-Blue-Diffusion-Treated-Sapphires&blobheadervalue2=abinary%3B+charset%3DUTF-8&blobheadervalue3=application%2Funknown&blobkey=id&blobtable=GIA_DocumentFile&blobwhere=1355958396200&ssbinary=true

I hope this helps.
