Looking for a gold tester that is reliable yet relatively easy to
use. Any suggestions pros or con would be appreciated. Thanks.
testing acids are cheap and reliable- I don’t know of an acid for
24k- but there are 10k, 14k, 18, & 22k as well as platinum- but
testing for what fineness of platinum contenet is questionalble.
there are lots of on line jewerly suppliers selling the acids. there
are also expensive karet readers- not sure yet how they work or how
reliable they are- has anybody used them?
The only problem I have using the acids is when testing a quantity of
gold- it is not great to be breathing it in and not great getting
drops on your skin- so the karet readers would offer relief from the
fumes. best luck- rona
Hi,
I am happy with my good old touchstone. And I love its oldfashonned
wooden box and acid bottles!

I use the Golden Touch for a quick check. It’s electronic and seems
reliable and accurate. The best is there is no need to file any
parts away. I also test with acid, when the electronic test is either
inconclusive or against my gut feeling 
You can buy it online, just Google “Golden Touch” gold tester. It
has been worth the small investment for me. It costs about $80.00
Now I wish they made one for Sterling and silver content. I have a
black touchstone and trying to figure out shades of red is really
tough. Does anyone know of another kind of test for Silver content?
Thanks!
