Jewelry-Grade Precision Nickel Testing Solution: Instant Detection at Your Fingertips for Exquisite Purity

I used this on two silver necklaces that I suspected contained nickel because they always gave me a rash within a week of wearing them. I tested them both with 3 drops of the solution on a Q tip. There's a strong ammonia smell (not acetone like one reviewer said) so its best to work in a ventilated area. So, on both of the necklaces, the Q tip came back unchanged and white. I was certain the product was crap, so I grabber a US quarter, dime, and nickel. I tested all three, and all three turned the Q tip pink. The stuff works, because nickel is present on all of those coins. I may indeed have a true silver allergy. This is worth the money.

Works perfectly. I use it to determine whether or not a guitar has stainless steel frets. It turns pink when it comes in contact with nickel. It takes a few seconds to use and it has been 100% accurate so far.

Doesn’t work. The smell is truly like a strong acetone, it made my eyes water. Which honestly I’d put up with the smell if it worked. But it didn’t. Idk why it worked for others and not me. I put it on a q-tip and then rubbed it just like the instructions on the bottle said. I tried it on several parties of earrings, necklaces and even stainless steel appliances. Apparently stainless steel appliances have a nigh nickel content. Nothing worked and I tried every stainless steel thing I could find in my home. Nothing made it react. It’s frustrating because I have developed a new allergy to my earrings and I don’t know why or what’s causing it but I was thinking it was the nickel since it’s the most common.

It works. Tested on coins and other metals to verify. Other people reporting it doesn’t work either got a faulty batch or do not know how to use it properly.

I recently developed a nickel allergy. This little bottle helps me test all of my jewelry making findings so that I can protect myself and my customers. I love the company and the seller and have bought several items from them over the years. I highly recommend this.. The only downside is the strong odor but It is tolerable.

Works well

Don't buy doesn't work. I tested as the bottle says and it didn't work. I tested it on my childs earrings that are nickel Free and no "pink" was seen. Then I tested my earrings (I don't need nickel Free) and the "pink" did not show. Plus the smell is awfully strong!!!! Too strong. My husband could smell it across the room. And it made my nose burn from the smell.

I have now a nickel allergy from wearing cheap necklaces that are made with nickel. So I am going through my jewelry and dumping the nickel ones. Using a q tip as recommended shows pink if there is nickel .

Item as described, prompt delivery, will buy here again, very satisfied.
