18K Gold Testing Solution for Jewelry, 12 g, Made in USA

If you are buying gold then you need this testing product. It is a lot to test with for the cost. It may save you hundreds of dollars by not testing before you buy gold.

Love using this to test my silver items so much easier to see it turns blue. Highly recommend

Save your money & look elsewhere if you are looking to test silver!!! This is the first time I have ever left a negative review. I just received 2 bottles of the 18k acid to specifically test silver. I had a bad batch of 3 bottle I bought a while ago and now just realized they were from this same company. Ugh. *** Acid is either weak, a bad batch or just not what it is suppose to be and did not react to sterling silver at all. Unfortunately, the bottles are not returnable. I didn’t bother testing 18k because I desperately need many bottles to test silver. I have loads of silver to test. Luckily I had a little bit left from an old bottle so I could compare and see that this new acid does not work as it should. I have to try to find a better source with acid that works… they too will be unreturnable on Amazon. So, 5 bottles purchased of 18k acid that do not react when testing silver. I have included a image with new acid and my old one. Now I am off to hunt for more.

Works perfectly

It’s works fine when you get a good bottle. The last three I’ve gotten were no good. It’s a crap shoot

Doesn't work.
