Hi, I found these rocks while working near wave hill in the NT, my guess is that they are probably jade but I'm not really too sure, hoping someone with a bit more knowledge can help me out. My second guess is kryptonite! Please help..
Sorry, But it is Prehnite.....Common around Wave Hill area... Citrine is a variety of Quartz and is yellow-orange colour.. and not found around Wave Hill that I know of... Although the above link says it is....
This is the site I use and find it much more reliable... www.mindat.org

Thanks for that, I looked up prehnite and now 100% sure that's what I have, dam....was hoping for kryptonite! Still its a pretty rock. Thanks for your help identify it..
