Flashing colours

Don't blink to confuse colour codes 
What do you hold, in fingers held behind 
I want to know, show me proof 


Provide the clarity to withstand my test of doubt 
Painted replicas do not count, would not stand 
Mounted glass still would not count for certified rocks


If I am to step on diamonds you attest to 
Would it be glass squashed, to shock naked of jewellery  
Dirt like the true value of content it holds  


Show me proof of what you are made of 
Show me your worth, in what you bring 
Do not blink to confuse colour codes 


Not this time my friend 
A gentleman's handshake would not do 
Not with 419 so much in style
