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

Have not used yet but I will moving soon

Used to test gold and sober jewelry. Works fine, nothing fancy.

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.

well, these things do go "bad" pretty fast, so this one I got as a replacement for my old test solutions that I never finished to the end, but they did go kind of bad, especially the one for silver. When that one turns brown from dark reddish, you may want to move on to the new one. The kit works great.

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.

This kit is so subjective. How can I tell if it’s real or not when the acid is the same color as what I’m testing? Kinda janky if you ask me.

Good deal.

This jewelry testing kit is a game-changer! It helped me accurately assess my collection with clear instructions and just the right amount of chemicals for personal use. Remember to use protection when handling acids! I'll definitely repurchase when I run out. ✨
