This kind of a concept track and you may not understand most of it. But, like it says in the song "you gotta read between the lines.

[Verse 1]
Diamonds are forever, for eternity, even better,
If this rap music dies let's rejoice and grieve together,
Weep together, cause it was said diamonds were everlasting,
Yo, I'm ready to sever basterds and begin my beretta blasting,
But perfect things fall down, and die, no they ain't with god now,
They never come back unless some hero, maybe savior calls out,
With quite the un-flawed style, resurrects something that once was,
Run-DMC, were youngsters, Pac lived, til 'em guns bust,
So how do we get these legends, these diamonds to shine again,
Rhyme again, crime and sin, through their lyrics blinding men,
As their art sparkles bright, as bright as the start of life,
They startle fights, cause diamonds don't gotta be talking nice,
Not even the darkest night, in hell at three A.M can stop 'em,
Block 'em, unlike fruits if you can stock 'em for years it won't get rotten,
So if diamonds are forever I won't be shining 'til I'm dead or,
Gone, cause I ain't climbing for the cheddar, so I'll be dining here forever!,
[Chorus]
[Verse 2]
Nothing lasts forever, so call me nothing, but tell me nothing,
But I'm something that gets knocked down and starts self-constructing,
I never get broken open, but my mother did when I was created perfect,
And when I lived, I got un-earthed, my life, I had to make it worth it,
When I came to being I was served with, a chance to be stronger,
Shine brighter, rhyme tighter, so I pranced to go wonder,
Become a man, think and ponder, and make myself a powerhouse,
I thought "okay the hour's now!", and I couldn't just coward out,
Soon enough I became what my brother's would have liked to have been,
Died to have been, but I was a demon inside, they cried when I sinned,
I can't help but to be influenced by my surroundings, what's around me,
I can't stop it when I see these other diamonds styling, I get to wilding,
So I assembled a military of my own, soon the cementary was my home,
My soldiers, my generals, my people buried I really worry that it's gone,
It's true, diamonds are forever, but a diamond's dynasty is limited,
Fuck this infinite shit, in a bit, my whole legacy, I'll be missing it,
[Chorus]
[Verse 3]
A diamond, now what is the true meaning behind this?,
Tell me, is this just lil old me wishfully dreaming of diamonds,
What am I truly saying by diamonds?, what is the real concept,
He's fucking crazy, some said, he's seeing things, some bet,
Maybe all the 'pressure' has gotten to this small silver rock,
Dude, claims he lives after being sprayed and spilled with shots,
If only I could explain what a diamond is but I man, I have,
If you read between the lines you'll just understand a half,
Of what it really does mean to be a graceful gemstone,
As you wonder if a diamond is who is sitting in thrones,
Or those who overcome and escape the great pressure,
Make tressure, instead of finding it, god may bless ya,
If only you were a diamond, but no sorry you gotta go,
While I smile eternally and eternally as I stock the dough,
Someday you may understand why diamonds are forever,
And I'll just sit here and be a diamond, rhymer don forever!,
