Black Star Sapphire Ring - NO Star!

I purchased a very inexpensive black star sapphire ring, so I didn''t really expect much in the way of very clear lines from the star, but I at least expected to see a faint star, even if squiqqley lines.  I don''t see any star!   It''s not returnable, so yeah I know buyer beware.  Just wondering what would cause this?  Not cut correctly? I do see the soft white light moving around inside the stone, like adulesence would I imagine from a moonstone.  I don''t have a photo i can upload at the moment, but have noticed during photo''s I have been able to take, the star does seem to come out with the flash, so maybe it''s just not enough direct light inside??????
