My other stones are smooth and easy to use. This one when scratched brings up little chunks of the stone and makes it not impossible but not trustworthy on results since the bigger the scratch the clumpier it becomes. So grainy makes no sense

Hard to see the gold when scratched on this stone I think it's because of the gray color but I would not recommend
