[QUOTE="Barra_Mad, post: 70252, member: 2114"] There is a couple steps to go through to identify a mineral firstly how hard is it will it scratch glass or will glass scratch it, If it is arsenopyrite it should be 5.5 - 6 on the MOHs scale meaning glass should scratch it. next make sure its dry and try get a streak on a white and a black surface it should streak dark grayish black. But going on the size it might be hard to test the sample but its most likely a sulfide which include your pyrite family, but knowing the part of the country you found it and reading a geological survey focused in or around the gold rush in the area should tell all the other minerals found in your rock, which will give you a short list to work off. here is a good place to start for reports [url]http://www.farlang.com/view_pages_by_tags?tag=Gold[/url] [/QUOTE]
