Jewelry Testing Kit 10K, 14K, 18K, 24K Gold, Silver, Platinum Test Solutions with Scratch Stone, 30X Loupe, Instructions, and Bamboo Storage Box

This metal testing kit comes with everything you need to verify the type and quality of metal you're looking at. In addition to this kit, you will need safety goggles, rubber gloves, and baking soda, in order to use it safely. The kit comes in an intricately compartmented wooden box. Most of the compartments are small and designed to hold your various acids and chemicals closely. It comes with a 30x jeweler's loupe and a scratch stone with a non-slip surface on the back. There is an included instruction booklet, but the procedure is very easy; scratch your metal item on the stone, back and forth a few times, in a spot that won't show the scratch. Really, the scratch is very minor; I couldn't see it without the loupe after I did it. But still, try to pick a spot in the back of the piece if you can. Next, apply your clearly marked, appropriate acid from the kit. Repeat if necessary (there are several formulas for testing gold). The instruction booklet will help you interpret positive or negative results based on whether or not the line dissolves fully, partially, or not at all. Then, carefully clean the stone with a solution of baking soda (to neutralize the acid) and water, dry, and put it away for next time. Easy and fun! It works great, and it takes longer to set up for the test than it does to do the actual test, which is pretty typical for sciencey things. My only complaint is, I wish the box had a poison sticker or brand on it, because something about the plain wooden box attracts people to it. They make a bee-line for it and open it without asking. I'll have to make my own sticker or mark, although that might make people even MORE curious. Anyway, that doesn't effect the quality or the accuracy of the kit, it's still a 10/10 for quality, accuracy, ease of use, and a really well-made storage box.

A+ Seller! Great product, packaged well, as described, reasonably priced, and shipped fast! Thank you.

Low cost and fairly bare bones, this kit works as intended and is sufficient for most people. Nice eyepiece included.

Very complete kit , nice for checking all the stuff we have gathered. 4 stars because of small stone size. Very small ans awkward to use.

Best quality of testing kit so far. Full liquids with a great box.

This kit had everything I needed. It worked perfectly.

Ordered to use as a second testing kit. The testing stoner was defective. I have been communicating for several days to get this part of the kit replaced. Now I am told it will need to be escalated to get a resolution. It should have been a simple testing stone replacement. They are probably one of the cheapest parts of the kit. I had to send multiple photos, and then they had me "clean the stone" that should have been clean when it was sent. There are now some other suppliers of these products on Amazon, so will just order another kit from a different vendor. Really a shame since the one I ordered from this company previously has worked really well. Customer service has been cumbersome and is delayed by the fact that they don't respond until the next day. The box is of quality, but the rest is not consistent in its quality.

This is a great product. The box keeps everything organized. It is easy to use and understand.
