"Dark Diamond" lyrics

Oh, I'm a dark diamond
I've turned hard and cold
Once was a jewel with fire in my soul
There's two sides of a mirror
One I couldn't break through
Stayed trapped on the inside, wound up losing you

Tell me how does it work
How do you make things fit
Spent all my life trying to get it right
I've put it together and it falls apart
I thought to myself I might understand
But when the wall's built
And the heart hardens
You get a dark diamond
Dark diamond

Oh, I'm a dark diamond
But you're something else
You read me more than I read myself
The one star I could count on
Only comet I could trust
You burnt through my life to the true meaning of love
