Gemtone Professional 14K Gold and Silver Testing Kit Solutions with Testing Stone and Neutralizer

Works great

Works really well for the price took a little practice but it works.

I’m enjoying using this testing kit, however, I feel the testing stone is much too small. And the lid just broke on the silver testing solution and I’m left wondering how to safely store it. Overall, a good product.

Exactly as expected, good value ,great for an amateur just checking old jewelry

I don’t know if it’s the user ( that’s me ) or if it’s the product, but I didn’t get the results that I was expecting. I tried the test kit on what I thought was pure silver and got mixed results. Then I tried the test kit a .999 Fine Silver US Mint coin and got less than pure results. I’m not an expert at this stuff, but I followed the instructions to the letter and made sure that nothing was contaminated, so I don’t know where the problem was. BTW, I used this product as soon as it was received.
