A very good job, some lovely bits of matrix there. I am about to try treating some I found while outback Australia at Andamooka. Hopefully it will work well. Is there any other acid you can use or substitute for the sulfuric acid? Regards Andy Poverty prospecting Australia 🇦🇺
@bialy100k Yes it's permanent but how deep the treatment penetrates into the stone varies per piece. Only way to take the carbon our is to soak in a heated bleach solution but it won't fully undarken it and it also damages the stone

@@MojaveMineralMiners okay thanks for the quick reply! Cheers Andy PPA 👍
Is this permanent? Wont loose colours and "style" on time?
