Hello everyone,
I am interested in using relatively high karat gold, but not 22K as this might be little soft. I want it to be at least as hard, maybe a little harder than sterling so will probably be higher than 18 but lower than 22. Probably in the range of 20-21 karat. However I fear people or even the government (I live in Canada) might not recognize these karats? What do any of you guys think?
