[QUOTE="BigWave, post: 518872, member: 6786"] Agree with RM that it looks a little like pyrite. You could try a multi-meter on it. Pyrite is a semi-conductor and will have a noticeable resistance. Gold will show negligible resistance. Pyrite is also brittle, so will not scratch with iron (may remove chips though), but will smoothely indent the gold. Disagree with RM though about Brickies acid (HCl), which may remove traces of ironstone and attack the pyrite (I am told), but will not dissolve quartz. [/QUOTE]
