I'm afraid it's very hard to tell anything from your images.
Would it be possible to take more pics. on a white background? - including a good, clear base shot.
I would suspect you have something good there, it looks as if there's been a lot of work finishing it off, cutting and polishing, but I really can't tell what it is what shape it is or how the colours have been put together in it.
I think you might have had some trouble resizing your pics too? They don't "blow up" very big.
