My Precious Bracelet

Rough seas crash my object around,
could cost more than a pound.
Black and grey,
always willing to play.
Feels harder than a rock,
same material as a lock.
Rougher than gravel,
taken a big travel.
I can see a big pirate ship,
using my object's images as a whip
Smells like a piece of metal,
never likes to settle.
You can hear the rough seas,
like a swarm of bees.
Tasted as cold as ice
and can act very nice.
Kept on a desk after a day of experiences, ready for tomorrow’s brilliances.
Gleaming in the middle of the night shining oh so bright.
