quartz or something else?

this struck my eye the other day, thought it might make a neat cab ..



the pic ain't great, but the main portion of the stone is a greenish color - the top portion is white like quartz. I would go with that, but have never seen green quartz, and am finding this stuff to be a little bit harder. This is also the only piece I have found here. Any input is appreciated!

could be an agate.

green quartz aka prasiolite or adventurine. two different forms, but still silicon dioxide (quartz).

thanks for the input - will look that up. Will post more pics once I get it cabbed, which after last night will be after I get my grinder fixed!

On that note - does anyone know where you can buy plastic cogwheels??
