The diamante is a poem form similar the the cinquain. It consists of seven lines, as shown below:

First line: a one-word subject that contrasts with the subject in line seven.
Second line: two adjectives which describe the subject in line one.
Third line: three verbs relating to the subject in line one.
Fourth line: two nouns related to the subject in line one, followed by two nouns related to the subject in line seven.
Fifth line: three verbs relating to the subject in line seven.
Sixth line: two adjectives which describe the subject in line seven.
Seventh line: a one-word subject that contrasts with the subject in line one.

There is also another, simpler type of diamante which contains only one subject. In this form, the first and seventh lines contain words which are two ways of saying the same thing. The example below demonstrates the former, more complex type.
