A Moss Agate

Moss agate they said;
fossilized algae.
Held to the light
its smooth surface reflects like water,
flecks of crystal, white bubbles of roiled foam,
the soft whorls of green, still alive.
A view of some quiet water's algaed-edge,
the glitter and gloaming from a stream long gone;
a fossilized moment in time.

Would this stony seed
if placed on a bright and sunny hillside,
then carefully listened to,
like a seashell against one’s ear,
release the mummer of a summer’s breeze
belonging to the day a millennia  past?
