An emerald is as green as grass; <br />A ruby red as blood; <br />A sapphire shines as blue as heaven; <br />A flint lies in the mud. <br />A diamond is a brilliant stone, <br />To catch the world's desire; <br />An opal holds a fiery spark; <br />But a flint holds fire.<br /><br />Christina Georgina Rossetti<br /><br />http://www.poemhunter.com/poem/an-emerald-is-as-green-as-grass/
