Snowflake Obsidian

Like snow speckled asphalt,
Put into stone,
All rolled into one,
Its origin unknown,

Its story is special,
Found far away,
Deep underwater,
No light from the day,

Smells like mint,
Tastes like gold,
Looks like a gemstone,
Never grows old,

As smooth as a pebble,
It has a meridian,
Now you can guess it,
It’s a snowflake obsidian.
