Aww Cara I truly adore this poem, it is really beautiful and not like your other recent ones.
The way you related to the diamonds is so very interesting, it is something which was meant to be valuable but now a days people go for the most expensive diamonds because they think the price of it sounds better than the diamond would even look anyway.
Your ending is quite inspiring, just think, if every human thought this way, would there ever have been a war??
