Aquamarine.

In the water, I am beautiful;
serene, when its sirens sing
me into seabreeze slumber.
But its rage can wreak havoc
that roars then rips through
roads and rocky mountains.

Elemental eloquence, its
ecosystem is a universe of
underwater excellence.
Aquatic artistry is evident in
every detail, from insignificant
algae to blue whales in all their
breathtaking magnificence.

Capable of capsizing acclaimed
ocean liners that could never sink,
or erasing entire continents
whose Atlantean existence still
remain an unsolved mystery to this day.

Poseidon's power knows no limits,
he could be both—the calm, but
also the storm.
Seamonsters, spinning cyclones,
tsunamis, and hurricanes could
just as simply become seashells,
sandcastles or skipping stones.

And in spite of all its splendour,
we must always remember that
no shipwreck or buried treasure
is worth risking the wrath of rivers
or the ocean's unpredictable nature.
