In Touch With Nature: To a Seashell

Who crafted your ripples,
your scruffs and your greaves,
now broken and empty
but still a beauty to behold,
surviving the tides and the cold and the dark?

The sea has sculpted me,
sturdily, carefully,
and placed within me
a young charge.
Within my cupped hands,
my small, irregular hands,
my rough, dark hands
this young life grows.
And when it ends,
I still bring joy,
for I am found,
and others wonder
at how smooth I am inside
and my pearlescent shine.

This is another from the school set, which means it' years old. Theme was asking a question of something from nature and writing it's response.
