I've used this acid mainly on silver and it's good enough. Sometimes it takes a while for the red color to appear. The testing stones are pretty bad though. They do work at least.

Easy to use and priced competitively

Value for money: I buy and sell a lot of precious metals that I find at estate sales and thrift stores, and this product has made my life so much easier. The testing acids are clearly labeled, easy to use, and give fast, reliable results. I especially appreciate the inclusion of the testing stones Whether I'm checking for gold or silver, this kit gives me confidence that I'm accurately identifying metals before I list them. I highly recommend this product for anyone who regularly deals in secondhand jewelry or antiques—it’s a solid investment that pays for itself quickly.

Testing gold on the stone seem to work. Silver, however, didn’t produce a color change with the indicator on the stone. I have lots of scrap silver laying around which the indicator color change seem to work just fine when I put the indicator directly on the metal, but I don’t know how you would check a piece of jewelry. No response from the seller.

great
