Shell ID

[cheungcalove]

Hello,

I could be completely wrong, but I think that these may be shells of some sort.  I saw them hanging so beautifully on a wall.  It's time for some professional opinions.  Could someone please help me identify these?  They are fairly large, about 7-10 inches across, and they felt hard and striated.
