Inclusions in Asha's ?

I just received my 8mm H round Asha in a trellis setting. I love it! It's so pretty and sparkling. However, I noticed that there is a black spot slight off center, but is in the the stone itself. Are they suppose to have inclusions? I have an email out to customer service but thought I'd ask here. I have not taken the tag off and don't want to of I can not return it without it. However, I really!! want to wear my ring. I waited 4 weeks for it.
