Where does your shell come from. Can you send an image of that to conch-l
to see the shape.
Otherwise it could be that you are joking. It could be a Telescopium (but
not Caribik) or another
Potamididae. What is the color of the shells. Are there any ribs. It could
be a young Strombus.
I don't think that also Turritella has such a large diameter. It could be a
Trochus. Or an
artificial handwork that was beached. At least you should go to the eye
doctor for better
measuring.
with best shelling greetings.
