My Obsidian

As black as the universe's endless void,
It came from a calamitous eruption that I'd rather avoid.
Although it is dark it has a plethora
of beauty and magic just like an aurora.
In rays of daylight it glistens and glimmers,
Just like a crystal that sparkles and shimmers.
The obsidian is like an exotic bird's eggshell,
it may not be prized but it is very special.
My talisman has a smooth rock exterior,
matched with a deep black interior.
dark volcanic glass, stronger than metal,
was formed in a place were my ancestors settled.
