Another mom shared with us that this is a shark's eye shell. The shark's eye is named because of the pattern of its body whorls. The early whorls are closer together, darker, and surrounded by paler whorls. This popular shell is smooth and porcelain-like. The underside is whitish and there is a chestnut brown lobe near the center of the underside.
I know it doesn't look pretty but wait till you see what you can make from it.
